✅ How to remove wheels from an office chair

Office chairs and armchairs are integral elements of furnishing any workplace. Most often with a soft back and seat. Adjustable in height and tilt. It is installed on rollers, which allows them to rotate and move freely.

As the name suggests, office chairs are used in the office, however, almost every home has a computer and therefore a comfortable workspace with an office chair.

The popularity of computer chairs is due to the fact that no back can withstand working at a computer for a long time, on an ordinary kitchen chair with a straight back or an ordinary chair. Office chairs are the only ones that are designed specifically for long hours of work. Fortunately, there is a huge selection of such chairs; everyone will find a model to their liking.

How and why do wheels break?

Computer chair wheels, although durable, still have some weaknesses.

The rollers, unlike the entire structure, are holders of the main weight, which rests on the entire product. Even ordinary dust can reduce their service life by clogging moving parts.

They can break and fall off for various reasons, but the main ones are:

uneven surfaces on which they drive;
exceeding the permissible weight for one product;
mechanical damage;
upon expiration of service life.

Naturally, it is not advisable to purchase a new chair just because of one caster, especially if a person is already accustomed to his workplace. And then the desire arises: I’ll take it apart and change these wheels myself! The main thing is to know how to remove the wheels from an office chair and then attach new ones.

Procedure

A standard office chair is not a complex mechanism, especially when it comes to wheels. Removing them will not be difficult, and you don’t even need any available tools. The thing is that they are simply inserted into specially made holes in the crosspiece and secured with a small click.

You can fasten them yourself, by hand. The main thing is to put in a little effort so that they do not break again during use.

It is most convenient to do this with a disassembled cross, then the top of the product will not interfere with a tight fit. But even with this approach, completely replacing all the rollers will take you no more than fifteen minutes. This suggests that there is no point in turning to someone for help; even a fragile woman can cope with this task. The advantage is that you don’t need a lot of knowledge to understand how to disassemble the wheels of an office chair.

What to pay attention to

Assembling an office computer chair does not require much effort. By following the step-by-step instructions, you can prepare it for use without any problems:

install the wheels into the slots of the cross;
install the gas lift into the crosspiece;
Screw the rocking mechanism to the seat.

To properly assemble an office computer chair, you need to try to do it by following these instructions. After assembly, you need to check whether the work was done well. To do this, you need to sit down and evaluate how comfortable it is and how functional the product is. If any difficulties arise, you can contact a technician or try to figure out where you got the error.

After assembly, you can adjust it to the required parameters. One of the important and common features is the height adjustment of an office chair. It should be such that it is convenient to work at the table, as shown in the picture below:

Customize your office chair with backrest adjustment by choosing different positions:

for work - vertical is suitable;
for relaxation, you can lean back and let your spine relax.

To find out how to adjust your office chair most effectively, you need to analyze which position will be most comfortable for you. To do this, you need to place your hands at the same level as your elbows, placing them on the table.

The adjustment mechanism of the office chair can be adjusted without any problems. Change the height using the lever located under the seat.

If you are trying to figure out how to assemble an office chair, then these instructions will definitely help you. Of course, it is different for each model, but they are all similar to each other, so coping with such a task will not be difficult even for someone who has never done this before.

And finally, I would like to recommend the Brabix office chair, with which you should not have any problems with assembly or operation:

Additional Tips

The task becomes even easier if it disappears on its own. Excess parts can be pulled out using a screwdriver; they will no longer be suitable for any purpose. Experts advise making a complete replacement, since different types of wheels can make it difficult to move on the floor covering. And in general, timely replacement will ensure a longer service life of the rollers.

This information on how to change wheels on office chairs will also help if you had to assemble a new model yourself and without instructions.

How to disassemble a chair before replacing it

In order to replace the roller wheels or simply clean them of debris, you need to remove them. Anyone can cope with this simple task without the help of a specialist.

ATTENTION! Before removing the rollers, it is recommended to drop lubricant into the place where they are attached. This will make your job easier!

First, turn the chair upside down. Then, using a little force, pull out the wheel. If the roller cannot be removed, pry it off with a screwdriver. Sometimes it happens that the wheel comes out, but the pin remains. In this situation, pull out the pin using pliers. After this, the work of removing the roller wheels can be considered complete.

Due to a broken landing pin for attaching the wheels, a lack of locking rings on the rollers, or wear on the crosspiece plug, the wheels begin to fall out. We will replace the crosspiece by partially disassembling the chair. Turning the office chair upside down, remove the wheels using the method described above. To remove the crosspiece from the gas lift, you need to hold on to the gas lift and gently tap it with a hammer from above around the connection point. The broken part can be easily removed.

IMPORTANT! Rollers falling out is the most common failure in chairs.

In order to ensure that all parts remain intact after disassembly, you need to act carefully, without using excessive force. Then it won’t be difficult to collect them.

Wheel installation sequence

After removing the damaged rollers, we replace them with new ones. Just insert the wheels into the cross. At this time we will hear a click. The wheels have been replaced. If, when changing the casters of a computer chair, the crosspiece was replaced, then the office chair is assembled in this way: we install the new wheels into the crosspiece using the already familiar method, then we insert the crosspiece into the gas lift.

ATTENTION! The gas lift fastening on all types of standard seats is the same, so you don’t have to worry about its incompatibility with the new cross.

There are several types of crosses: wooden, chrome, plastic. The most reliable is chrome plated. When purchasing this important part, you must be guided not only by the material of manufacture, but also by the appearance. It should be perfectly coated, without flaws, with well-finished edges.

Surely the above tips will help you easily replace the wheels and avoid buying a new chair!

How to clean hair from office chair wheels

Chairs on wheels are very practical, comfortable furniture that is popular not only in office spaces. All this thanks to the stylish modern design, convenience and maneuverability. Due to the high mobility of the wheels, you can easily move short distances without even getting up from your chair. What can we say about official office chair racing competitions... But, sooner or later, the parts become unusable. And here there are already two options - replace the wheels with new ones or clean them yourself. As for cleaning, it is not that difficult, and you can deal with damage that has occurred due to accumulated debris without outside help.

Why do wheels sometimes break?

Of course, the two main reasons why wheelchairs on wheels break are a manufacturing defect or a worn-out landing pin. But this only applies to those cases when the chair is quite new and is even under warranty. But if the furniture began to work poorly after some time, then the first reason for such a breakdown is contamination inside the wheel structure. This includes dust, debris, hair, animal hair, and even carpet lint. They clog moving parts, thereby reducing the service life of components.

Naturally, the first thing you will notice is the inability to remove the wheel from the chair and clean it from the inside. Some structures are truly permanent, so they will have to be completely replaced. If the furniture can be disassembled, then even a teenager can handle cleaning the wheels.

How to avoid mistakes when adjusting

You need to set up the chair carefully. Check that you are comfortable sitting, typing on the keyboard, and reading text on the monitor. If necessary, the position can be adjusted during operation.

If you set up your computer chair correctly, the monitor will be directly at your eye level.

Often the chair is adjusted incorrectly, this can be seen by the sitting posture. A hunched back and a torso bent forward are the first signal that mistakes have been made.

The chair is too high or low.
Inappropriate position of the armrests.
Incorrect backrest angle.
The seat is too wide or narrow.

It is recommended to pay attention to models in which the back and armrests are adjustable using screws.
The body itself tells you what to pay attention to. If your back or neck hurts, check the angle of the backrest. Wrist pain may indicate problems with the armrests or chair height. And numb legs - the seat at the wrong depth.

Handle your office chair with care.

Be sure to customize your office chair, and this also applies to your home computer chair. Sitting for long periods of time harms the spine; by making the workplace ergonomic, you can at least slightly reduce the negative impact.

Adjusting the chair is easy and only takes a few minutes.

Modern office chairs have a number of adjustments that need to be adjusted to suit you. In this case, it is necessary to monitor the position of the body. If you follow all the rules, you can avoid mistakes and keep your back healthy.

How to disassemble a chair wheel to clean it

Typically, the design of chairs on wheels does not differ from each other. You don't need any special tool or special skills to remove them. All moving elements are attached to special grooves that are drilled in the crosspiece. The parsing mechanism is as follows:

Pull the wheel a little and pull it out of the hole in the crosspiece of the chair;
separate the roller itself from the protective plastic;
If the plugs are broken or worn out, they will have to be replaced with new ones.

Now you can start cleaning the wheels. If they are heavily soiled, remove as much accumulated debris as possible. You can use scissors or a knife, but you need to act very carefully so as not to scratch the wheel itself. Some owners have found a more effective way - a sewing tool for steaming seams or needle-nose pliers. They themselves are quite narrow, which helps to reach the most inaccessible places in the wheel structure.

Once all the twisted debris has been removed, you can additionally vacuum the wheels to remove as much dust and small hair as possible, and only then proceed to washing.

Washing chair wheels does not mean anything unusual. It is enough to wash them in soapy water, rinse and dry well.

There is one very important point in this whole process: before sending the rollers into place and assembling the entire structure as a whole, all parts must be dried very well. Otherwise, mold, mildew and even rust may form from excess moisture.

Working behind the monitor. Why do you need a computer chair?

A little anatomy:

Structure of the spine
The human spine is divided into 5 sections: cervical, thoracic, lumbar, sacral and coccygeal. The spinal column itself has a curved shape, which provides shock absorption during movements, evenly distributing the load on the musculoskeletal system. Curves are divided into two groups - lordosis (areas curved forward) and kyphosis (areas of the back curved backward).

If changes occur in any of these curves, this will affect both posture and sensations, as well as the person’s health and ability to move normally.

Scoliosis and other curvatures

The most common acquired diseases of the spine are scoliosis (a typical curvature of the spine along one of the axes), osteochondrosis (disturbances in the functioning of cartilage) and intervertebral hernia.

All of them lead to limitations in mobility, as well as to serious chronic diseases that only worsen with age.

And why? Because we sit incorrectly – whether at home or at work. To prevent back pain, we need orthopedic support for the back and pelvis. This is exactly what a computer chair is designed for.

What criteria should you pay attention to when choosing a computer chair (CC)? All characteristics of the CC can be divided into two groups - adjustable and non-adjustable parameters.

Of the adjustable parameters:

Armrests
Chair height
Backrest tilt
Chair rocking

The presence of armrests on a computer chair is fundamentally important - after all, they are responsible for the correct positioning of the hands when working, which directly affects the condition of the shoulder region. An important point is the ability to adjust their height and width relative to the seat. If it is not there, then you will have to choose the chair especially pickily - after all, there will be no opportunity to change anything. Stationary armrests can also be comfortable, but this must be determined during direct “trying on”.

The height of almost all computer chairs is adjustable. This parameter affects not only how your eyes and hands are positioned relative to the work area, but also the position of your legs. The angle at which your knees are bent, with your feet on the floor, should be 90 degrees. Otherwise, your legs will become numb, sore and lose mobility by the end of the working day.

Why do you need to adjust the seat backrest? So that you can calmly recline in it during a period of short rest, allowing your back to relax. This will increase the duration of your work without discomfort and, as a result, your performance.

Also, some models of computer chairs are equipped with a function that allows the seat to move forward and the back to tilt back, which allows the person sitting in it to recline into a semi-lying state. At the same time, the chair seems to “swing” backwards. This feature is completely unnecessary at work, but very nice if you are buying a CC for home. Changing posture has a positive effect on the condition of the back muscles, which in turn affects the musculoskeletal system. This function can be disabled in situations where it is not needed.

Of the non-adjustable parameters:

Back shape
Seat and back material
Base material
Gas lift reliability
Build quality

The backrest parameters are purely individual and are selected depending on the height and dimensions of the seated person. At the same time, they must precisely correspond and provide support to all curves of the spine. A chair that costs a lot of money may simply not suit your height and will only aggravate the condition. It’s quite simple to check whether the backrest of a particular seat is suitable for you - you need to sit on it and lean back, completely leaning your back. If you feel that something is pressing into your lower back or shoulder blades, forcing you to bend at an unnatural angle, then this backrest shape is not suitable for you.

As for the upholstery material, it must have good absorbency. Good options would be mesh or genuine leather, as well as rough fabric upholstery. The worst thing you can choose for upholstery is artificial leather. Your own, natural one will sweat, untidy sweat stains will appear on your clothes in the places where you lean on the chair (if you know what I mean).

Equally important is the material used for the KK cross. Most often this is one of two options - plastic or steel. The metal base is a little more expensive, but its strength is much higher, which means it will last much longer. In addition, increasing the weight of the crosspiece provides greater freedom of action for the user of the chair.

Remember when we said that a computer chair should be able to lower and rise? This applies not only to the moment of setup, but also to constant operation, during which the CC moves down when you sit on it and rises up when you get up. This “elasticity” is provided by a device called a gas lift or gas cartridge. In the event of a malfunction, it begins to knock obsessively with any sudden movements on the chair and even stops rising, forever sadly frozen in a lowered position. It is not possible to fix it yourself, but this is a manufacturing defect that is subject to replacement under warranty.

Well, build quality is the cornerstone when choosing any more or less large item, be it appliances or furniture. Even the best thing can be ruined by crooked hands.

That's it for computer chairs. Oh yes, the price. Are you sitting well? The price for a more or less high-quality chair starts from 7,000 rubles (in the simplest configuration) and rises to infinity - depending on the wishes of the customer and the manufacturer. The optimal price-quality ratio can be achieved in the region of 10,000 – 15,000 rubles.

In what cases is it necessary

Before studying the question of how to remove a wheel from a computer chair, you need to find out the nature of the malfunction. Roller failures come in several forms:

the wheel stops rotating;
scratches the floor surface;
falls out of the mount.

The reasons why the casters on an office chair are damaged can be different:

contamination - dust, dirt, threads, hair, falling on the wheel, clog it, interfere with proper functioning, which leads to premature wear;
heavy weight - constant loads contribute to breakage of small parts, fasteners, including the wheel;
mechanical damage – careless use often leads to malfunctions;
unevenness on the floor - due to prolonged use of the chair in such conditions, the socket becomes loose;
wear and tear – the lifespan of a computer chair is limited; over time, parts wear out and require replacement;
manufacturing defects.

Regularly cleaning them from dirt and foreign objects will help prolong the life of your wheels. Thanks to such procedures, the rollers will be able to move freely without feeling any obstacles. Replacing broken parts is always easier and cheaper than buying a new chair - they are available and easy to install.

For carpeted floors, it is recommended to choose a chair with smooth wheels; for slippery surfaces, it is advisable to use rubberized casters.

Office chair mechanisms

We will try to tell you about all the existing mechanisms for office chairs, their advantages and differences. First of all, it should be noted that for different categories of office chairs there are different mechanisms and, accordingly, their functions differ in dynamics and functionality. Computer chairs, or as this category of operator chairs is also called: This series uses three main mechanisms, which generally have the same functions, but also have differences; the very name of the series, computer or operator chairs, speaks for itself - these are products that should provide maximum comfort for working at a computer or desk, they should have a low price.

Permanent Contact or CPT - installed on inexpensive chairs, has three main functions - tilting the backrest and fixing it, adjusting the seat depth and backrest height, raising and lowering the chair using a gas lift. Most of the popular inexpensive computer chairs Prestige, Martin, Grand, Regal and the Metro chair are produced with this mechanism. The freestyle mechanism or (FMS - spring-screw mechanism) is based on an elastic spring under the seat, which fixes the oval holding the back of the chair. Provides constant free swing with adjustable deflection force. The rigidity or tilt force of the backrest can be adjusted depending on weight and comfort. It is considered a particularly reliable mechanism due to its simplicity and all-metal construction. Synchro mechanism - Sinhro - a modern mechanism with many adjustments, installed on expensive models of computer chairs. A distinctive feature of the mechanism is the adjustment of the backrest tilt and fixation, adjustment of the backrest height and seat depth. The mechanism is reliable and very durable. It is especially effective when used in places where office chairs are used with increased use and where there is a need to fine-tune the workplace. The asynchronous mechanism is a more professional modification of the synchronizing mechanism; it has an additional function, adjusting the seat tilt independently of the back of the chair. Allows you to choose the optimal position of your legs and body during prolonged work at a computer or desk. Ovalina is a mechanism that is a metal plate in a plastic corrugation that connects the seat and back of the chair. Does not provide for adjustments. When using Ovalina, the backrest is rigidly fixed. Very often used on industrial chairs with seats and installed on children's chairs.

PRINCIPLE OF OPERATION OF MECHANISMS ON COMPUTER CHAIRS:

Executive and mesh back chairs:

Piastra - The support performs the function of adjusting the chair height; a swing mode is not provided; it is used for chairs with a mesh back and executive chairs in economy class. Top gun is the most common mechanism for office chairs with a set of necessary adjustments and excellent reliability and functionality. By default it is installed on all models of executive chairs, regardless of the series. The tog-gun has several adjustments: swing mode, fixation in a working vertical position, and adjustment of swing to the weight of the person sitting. Also, with the help of a gas lift, the chair is raised and lowered in height. The top gun Lux adds to the standard mechanism the function of fixing any angle of the chair. That is, having deviated to the angle you need, you can fix it and remain in this position as long as necessary without applying any effort. It is considered a professional mechanism for managers who spend a long time in a chair. Multiblock is a modern and most practical mechanism for office chairs. Many adjustments and reliability allow us to consider it top-end and, naturally, installation on an office chair requires costs from the buyer. But this investment is completely worth it. The multiblock has a very smooth swing compared to other mechanisms; it allows you to fix the chair in five basic positions when tilted; in the standard position, the chair with the multiblock is slightly tilted forward, which ensures the correct position of the body and legs during long-term work. The multiblock can withstand a working weight of up to 150 kilograms. There is also an “anti-shock effect” - if you left the chair in rocking mode and removed the lock, then when you sit down, the chair will not tilt sharply back, but will remain in the set position; to unlock it, you will need to slightly rock back until it clicks, then the rocking will resume .

PRINCIPLE OF OPERATION OF MECHANISMS ON DIRECTOR CHAIRS:

Tools

Before you remove the wheel from your office chair, you need to prepare your tools. In modern models this can be done without special devices. But there are cases when the chair has been in use for quite a long time, the parts have become deformed, bent, or worn out. Detaching the roller in this situation is a little more difficult. To make your work easier:

Screwdriver or special plate. The thin part of the tool is used to pry up the wheel and carefully detach it. A screwdriver is also used to remove the plugs into which the rollers are inserted.
Pliers. During the process of detaching the rollers, a metal pin may become stuck in the crosspiece. You can pull it out using pliers.
Regular or rubber hammer. Helps, if necessary, to dislodge a wheel that is stuck. In addition, a rubber hammer is used to release the gas lift.

How to remove wheels

After examining the possible problems, you can begin to fix the problem. Guide on how to remove a wheel from an office chair:

turn the chair over and place it on a stable surface;
try to detach the roller from the chair by hand;
if necessary, pry up the casing with a slotted screwdriver, move it to the side, hook the wheel and pull it out.

Sometimes just disassembling the wheels is not enough. To transport or replace main parts, the chair must be completely disassembled. It can be done in several stages:

the chair turns over, using a Phillips screwdriver, the bolts connecting the seat and the piastra, a device that adjusts the height of the chair, are unscrewed;
the armrests are removed - the mounting bolts are removed;
the gas lift is disconnected from the piastra by gently tapping the piastra with a rubber hammer;
the backrest is removed from the chair - the special bolts connecting the backrest and seat are unscrewed;
The crosspiece is removed - a ring drift is placed between the crosspiece and the gas lift and knocked out with a hammer.

Assembling a chair is more difficult than disassembling it. After removing the wheels from your office chair, you need to carefully pack all the parts so that not a single part gets lost.

Back

This is probably the most annoying breakdown. If the back of the chair does not lock, then the permanent contact that regulates the connection between the back and seat is faulty.

The permanent is a non-separable part, so the part should be removed (this is not difficult, you just need to unscrew four bolts) and replaced.

Even such a cosmetic defect as worn upholstery can be corrected by purchasing fabric at the store and using a furniture stapler.

These are just the most basic breakdowns of office chairs. Yes, if you do your own repairs, you still have to pay for new parts. But such repairs will cost several times less than buying a new chair. Not all elements can be repaired, and in many cases you cannot do without the help of a specialist.

Sequence of installation of new parts

After you have disassembled the office chair wheel, you can begin to inspect and possibly replace the broken elements. The option for repair and installation of new parts depends on the nature of the failure:

The rollers do not rotate. Possible cause: contamination. The chair is turned over, the wheels are detached and inspected. If there is dirt and dust, they are cleaned with a brush or scissors (if they are wrapped in hair or thread). After you have managed to clean the wheels, they need to be washed and dried. Dry rollers are installed in place.
The wheel falls out. Malfunction – the plug (the socket in the cross that secures the roller) is worn out. It needs to be replaced. To do this, the wheels are separated and the plastic protective covers are removed. Then, using a screwdriver, the plugs are pulled out. New sockets are installed, housings and rollers are returned to their place.
Wheel damage. The roller itself or the locking ring, which is located on the axis of the landing pin, has broken. Thanks to this detail, the rollers are springy. Many people do not know how to change wheels. There is nothing complicated about this. The broken part is disconnected, the socket is inspected for damage and foreign objects, and a new wheel is installed.

In addition to damage to the rollers, other damage to the computer chair will occur:

Gas lift malfunction. This is a detail that is responsible for a person’s comfortable position while working. With its help, the chair takes the desired height and backrest position. If the gas lift is broken, the seat does not rise, falls strongly or skews to one side. There are two ways to repair the chair - replacing or fixing the gas lift in one position.
Broken crosspiece. This chair is quite durable, but if it breaks, the only way is to change it. Metal crosspieces are more durable and expensive, plastic ones are lighter and more affordable.
Backrest malfunction. If the backrest does not lock in the desired position and hangs, then it needs to be changed. If the permanent contact handle, which secures the backrest, does not work, it is advisable to replace the permanent contact.

When disassembling the chair, under no circumstances should you knock on the gas chamber. You need to remove the gas lift carefully, striking accurately along the edge.

Damaged computer chair wheels cause a lot of inconvenience. Finding out the cause of the breakdown and eliminating it is easy and simple. This does not require special knowledge or professional tools. You can do the repair yourself, without the help of a specialist. This will save time and money.

How to assemble, disassemble and repair a computer chair?

02.11.2015

Sitting at a computer desk on an ordinary hard chair means not respecting yourself. Today, computer chairs and chairs have become very affordable, but they are very bulky when purchased, and in most cases they arrive to the buyer disassembled in packages.

After the treasured box ends up in the house of its owner, the latter is faced with a logical question: how to assemble a computer chair? Turning a pile of spare parts into a chair will not require much effort or time if you know the same order of the assembly process.

Let's say right away that assembling a chair is much easier than assembling a computer desk, so if you have mastered the latter, then assembling a chair is no longer scary for you.

Assembling a computer chair on wheels

After the box with the chair is unpacked, you should carefully examine all the parts contained in the package for cracks, chips or scratches.

The standard kit includes the following parts:

Seat with backrest or solid monoblock.
Two armrests.
Rollers (5 pieces).
Screws.
Pneumatic cartridge.
Crosspiece and linings on it (if necessary).
Mechanism for connecting the seat with the backrest.
Gas lift casing.

Instructions on how to assemble a computer chair:

First of all, the rollers are inserted into the cross. In order for the pin to enter the beam of the crosspiece, you need to press the wheel with a little force. To make this more convenient, place the crosspiece on the floor. If you cannot insert the roller manually, you can use a rubber hammer and gently tap it on the base between the spheres of the wheel. However, you should not hit the rollers themselves, as they are made of plastic and may break.
After mounting the wheels, turn the cross rollers down and install a pneumatic chuck in its center. Then a casing is put on it. At this stage, you need to pay attention to the top of the pneumatic cartridge: some manufacturers put a decorative cap on its button, which should be removed. If this is not done, the chair may not lower or rise during use.
Now you need to install the armrests. To do this, you need to turn the seat over and inspect the place where they should be installed. As a rule, the armrests are attached with three screws. After a careful inspection of the armrest, you should determine where its front and back parts are. Next, the screws are inserted into the holes and tightened. In some models, the armrests are attached to the metal base of the chair and brackets are used for this.
After the seat is assembled, you should install it on the pneumatic chuck and press on top. You can also sit down in a chair to ensure that the air chuck fits tightly into the base of the chair.
If the seat is not monolithic, but consists of a separate seat and backrest, then carefully insert the backrest into the seat. Now you need to tighten the large fixing screw. Next, the backrest is placed on the corner and tightened with a short screw.

How to repair a computer chair?

If a computer chair fails, it can either be repaired or replaced. In case of minor damage, you should purchase the part that has failed and replace it. It is worth noting that repairs can be more expensive than buying a new chair. Therefore, it is advisable to first roughly calculate how much the repair will cost.

Step-by-step instructions on how to repair a computer chair with your own hands:

If the rollers fall out of the crosspiece, it is necessary to replace the plugs, that is, the sockets into which the wheels are attached. If the latter have defects, then it is better to replace them with new ones. You can purchase a kit with wheels and plugs, which will simplify the repair process.
If the backrest adjustment fails, when it is not possible to fix it in the desired position, you should inspect the permanent contact screw for broken threads. In this case, you just need to replace the screw. If the permanent contact fails, it must be replaced. To do this, you need to unscrew the bolts that connect this part to the back and the chair.
If there is significant play in the back of the chair, you should check the place where the permanent is attached to the back. If it bends, you need to try to straighten it and tighten the fastenings with a screwdriver. If no visible damage is found, the swing mechanism should be replaced.
If, when you lift the lever, the seat does not rise, or it rises, but when you sit on it, it falls, the air cartridge needs to be replaced.

You should know that this part may break immediately after installation in the cold season if it is not kept in a warm place for 12 hours after purchase.

If the chair begins to wobble and squeak, you can try tightening the screws in the place where the piastra or Top Gun mechanism is attached to the seat. If such actions do not give a positive result, and it is not clear how to repair a computer chair, you need to replace the pneumatic cartridge.

How to lower a computer chair?

To create comfortable conditions while working, to avoid back pain, pinched nerve endings and other health problems, it is necessary to adjust the height of the computer chair.

On both old and new (pneumatic) models, you can easily change the height by turning a special lever or bolt.

Before starting to work at the computer, you should make sure that the height of the chair is adjusted in accordance with the level of the table and your height:

First you need to install your computer chair at the table or the place where you plan to work. This is necessary to estimate the distance by which the chair needs to be raised or lowered.
Now you need to find a mechanism to adjust the position of the chair. As a rule, on all models it is located under the seat. On old-style chairs this will most likely be a massive screw, and on modern pneumatic chairs it will most likely be a lever or button.
In order to perform such an action as lowering a computer chair, you need to lift the lever up, as a result of which the seat will smoothly lower under your weight as long as you hold the lever.
To raise the seat, stand up from the chair and pull the lever up again. The seat will rise smoothly as long as the lever is held. As soon as the seat position reaches the desired height, the lever should be released, as a result of which the seat position will be securely fixed.

In some models you can find a lever or screw under the seat. This means that one is designed to adjust the height of the seat, and the other - the angle of the backrest. The locations of the levers, screws and buttons are different for each model of computer chair, so to figure out which lever is for what, you just have to try to twist or press them.

Although it is most convenient to adjust the seat height while sitting, it is recommended that you stand up before doing this. This will allow your chair to last longer.

In addition, it should be remembered that too frequent operations of lowering and raising the seat lead to premature wear of parts and mechanisms.

Therefore, if family members are of different heights, it is recommended to purchase their own separate computer chair for each of them.
