DIY office chair gas lift replacement

Causes of office chair breakdowns

Before you begin making repairs yourself, you must:

• understand the design of a piece of furniture;
• find out which element is faulty.

Computer chair design

The main components of an office chair are:

• seat and back;
• permanent - a contact connecting the backrest to the seat and allowing you to adjust the angle of inclination;
• armrests;
• piastra - the mechanism by which the chair is controlled;
• gas lift providing seat height adjustment;
• cross with rollers, acting as support and moving mechanisms, respectively.

Main components of an office chair

Definition and causes of malfunctions

The presence of malfunctions in the operation of a gas elevator (lift, gas cartridge) is indicated by the following aspects:

1. the gas lift does not hold the seat in the specified position;
2. the seat does not lower or rise when operating the control lever;
3. the seat goes down under the own weight of the sitting person;
4. the chair is tilted from its axis to one side;
5. the chair “swings” in different directions.

Signs of a malfunction

The main reasons for the formation of these malfunctions are:

• lack of lubrication in the mechanism. During the entire period of use, the gas lift requires periodic maintenance, which consists of applying lubricants;

Special composition for gas lift lubrication

• natural wear and tear. Manufacturers guarantee the operation of the mechanism for 18 – 24 months. After the specified period, it is necessary to carry out repair work or replace the main furniture units;
• improper operation: exceeding the permissible load level, jumping on the seat, and so on.

Failure options

A computer chair is a complex mechanism, and breakdowns, alas, are an inevitable reality.

You can save money by repairing the chair, or replacing broken parts yourself.

Professionals identify several of the most common faults.

1. Broken crosspiece. This is a fairly common problem with plastic crosses. If your model has a crosspiece made of metal, you have nothing to fear; they break extremely rarely. The intersection of the beams is in the risk zone of the plastic cross.
2. Deformation of the rocking mechanism. Because of this problem, you are unable to rest against the vertical and elastic backrest. If the backrest falls back, this indicates a malfunction of the position locks.
3. Gas lift failure. In this case, the office chair does not maintain the specified height. Most often we are talking about deformation of the pneumatic cartridge. This part has a two-chamber structure, and each chamber is filled with air or gas. And if, when you press the lever, the mechanism does not operate and does not lower, then most likely the piston, seal or other element of the system is faulty.

If you are replacing a gas lift in the cold season, do not use it right away.

Gas elevator repair

A gas lift for an office chair consists of the following elements:

• outer casing made of high-strength metal;
• a cylinder consisting of two reservoirs and equipped with a bypass valve;
• a piston with a rod located inside the cylinder and intended for lowering/raising the chair;
• button that is operated by the control lever.

Internal structure of an office chair lift

The gas elevator is a completely sealed equipment and even if a breakdown occurs, the gas cannot enter the surrounding air.

To achieve the specified level of safety in using the mechanism, gas is pumped into the cylinder exclusively under factory conditions. Therefore, you can only do partial repairs of the office gas lift yourself, which boils down to “jamming” of the mechanism in a certain position.

How to repair a gas cartridge by fixing it? To repair a lift and fix the lift at a certain level, you must:

1. gain access to the mechanism. To do this, remove the decorative plug (if any) and the pin - lock - from the lower part of the cross at the place where the lift is attached;

Disassembly to gain access to gas lift

1. the crosspiece with the decorative casing is removed, thereby opening access to the lift;
2. A piece of pipe suitable in length is put on the piston. It is this element that fixes the gas lift in one position. Therefore, it is important to determine in advance the optimal seat height and the required pipe length;

Fixing a gas lift with a pipe cut

1. The chair is being assembled.

How to remove the cross with your own hands

How to remove a broken crosspiece from an office chair?
To do this you will need special tools. But often they are not at hand, so a liquid for separating parts will come to the rescue. The connections can also be lubricated with kerosene, vinegar essence or soap solution. In order for the solution to penetrate the joints, you need to wait about 10 minutes. Repairing the crosspiece of a computer chair consists of several stages. First, remove the broken part in such a way as not to damage the lifting device, which is located in the cross itself. This element has the shape of a cylinder, and at the top and bottom it is cone-shaped. You need to disconnect the crosspiece with a special hammer.

First, remove the support by getting rid of the screws. Using the support you can adjust the height of the chair. Remove the seat before replacing the support.

Repairs are carried out using a rubber hammer, but if necessary, you can use a steel one.

A homemade chair requires effort if the joints have high humidity. Be careful not to overdo it so the hammer won't bend the support. In order to remove the support, you need to do the following: the cross is turned over from top to bottom, and under it we see a lock washer. Repair of this element must be as careful as possible, since the washer holds the cartridge rod.

Now you know how to repair a damaged crosspiece. In order to remove it safely, you will need to be patient. If you act carelessly, you can damage not only the cartridge, but also the mechanism itself for lowering and raising the chair. To ensure the process goes smoothly, we recommend watching the training video. With the proper skills, you can remove the cross from a chair in the office in ten minutes, maximum half an hour, if you have all the necessary tools.

When a computer chair requires repair, it is often necessary to remove the crosspiece. This way, it will be easier to change the gas lift, wheels and even refill the seat. It is important to know how to properly remove the cross from an office chair. Let's look at this in more detail.

Replacement of gas elevator

If the gas cartridge does not compress, and the device is required when using a chair, that is, fixing the device in one position is unacceptable, then a complete replacement of the mechanism is required.

To replace you need:

• prepare a certain set of tools and additional materials;
• familiarize yourself with the work flow chart.

Preparing to replace the gas lift

To replace the gas lift swing mechanism, you will need to prepare:

• new chair lift. You can purchase accessories in a specialized store. When choosing a gas elevator, you should take into account the dimensions of the equipment and the maximum load. If you can’t determine the parameters yourself, you can use the help of sales consultants;
• Phillips screwdriver for assembling and disassembling furniture;
• hammer. To ensure safety, it is better to use a hammer made of rubber. Such a tool will not damage the equipment during operation;
• ring punch;

Punch – a tool for pulling out (so-called “knocking out”) parts from holes

• vice. You can replace the gas lift without a vice, but using a bench tool will simplify the work;
• WD-40 liquid.

The most common breakdowns of office and computer chairs:

• The seat does not hold its height (it descends under the weight of the “passenger”) - most likely the gas lift is broken.
• The chair swings in different directions - you need to repair or replace the gas lift or the swing mechanism (possibly both).
• The chair tilts to one side - the swing mechanism, gas lift, broken crosspiece, or faulty internal frame may be broken.
• The height, tilt or swing cannot be adjusted - the reason lies in the malfunction of the swing mechanism.
• Roller loss occurs due to heavy load and wear. In this case, the chair can be repaired only in one way - by replacing the rollers.

Repairs may include: replacement of parts and mechanisms (including crosspieces), replacement of upholstery (fabric, leatherette, eco-leather), replacement of foam rubber, etc. It is easier and more economical for you to contact a professional technician if the mechanisms and parts of an office chair break down. who will disassemble the faulty part of the chair and replace it with a new one after repair in a workshop. In this case, the replaced parts and mechanisms will serve you longer and more reliably.

Definition of failure

If you do not consider yourself a professional, and you cannot figure out what exactly the problem is, adhere to the following rules:

• If it is not possible to raise or lower the seat, the tip of the gas lift lever is faulty;
• The chair is difficult to move even on a flat surface - the wheel hub is broken or the locking ring is missing;
• The chair tilts to one side - insufficient fixation of fasteners, manufacturer defects, excessive wear of the backrest mechanism;
• The back of the chair is too mobile - the permanent contact is worn out;
• The structure has lost stability - the gas lift or the swing mechanism is faulty.

Almost all chair failures are associated with gas lift.
Less significant, but requiring attention, faults are as follows:

• Damage to upholstery;
• Subsidence of the foam filler;
• Wheel breakdown;
• Piastra deformation.

Do not repair plastic parts using glue or a soldering iron.
These problems can only be solved by completely replacing the deformed elements.

Scheme and operating principle of gas lift

For everyone who wants to learn something new, we suggest familiarizing yourself with the diagram of a gas lift or pneumatic cartridge. Its operating principle is quite simple. The metal casing contains a cylinder in which a rod and piston move freely. The cylinder itself consists of two reservoirs, between which there is a special valve that can be opened or closed. When the chair is in its lowest position, the piston is located at the top of the cylinder. When we press the lever to raise the chair, it presses on a button that opens the valve between the chambers. At this moment, gas from tank 1 begins to flow into tank 2 and put pressure on the piston, which slowly lowers, thereby raising the chair. When you release the button, the valve closes, gas can no longer move through the cylinder and the chair is locked in that position. When you sit down in the chair and press the lever to lower the chair, you open the valve again, with your weight you act on the cylinder, it goes down, the piston goes up pushing the gas back into the external reservoir, while the chair smoothly goes down.

Functions performed by a gas piston:

1. Height adjustment of the chair (gas lift stroke depends on its size) 2. Torsion around its axis, in both directions, 360 degrees 3. Spring function when sitting in the chair, relieves sudden load on the vertebrae

It is necessary to mention such an important part of the gas lift - the bearing, which allows the piston and cylinder to rotate around its axis, thanks to which the office chair can perform rotational movements.

A large iron body serves to support the stem in the correct vertical position.

In the figure you can see a diagram of the gas lift, as well as its disassembled image.

The class is distinguished by the wall thickness of the middle tube and the outer tube.

Class 3 – 2.0 mm – usually for seats up to 120 kg

Class 4 – 2.5 mm – usually for seats up to 150 kg

Gas lift casing:

This part comes with the set as a decorative one, which covers the black glass itself and makes the bottom of the chair more complete. For chrome-plated pneumatic chucks, a telescopic case is not provided and is not supplied in boxes. This is done so that the chrome crosspiece is a single unit, and the entire bottom is metal.

Sequence of replacement work

How to remove the old gas lift from the chair and install a new lift? The work is performed in the following sequence:

1. treating all joints of stool elements with WD-40 liquid. This will make the disassembly process easier;

Lubricating units to facilitate disassembly

1. seat detachment.

How to disassemble the chair? Using a Phillips screwdriver of the appropriate size, loosen the bolts securing the seat to the piastre.

Next, the chair is turned over and the seat and decorative casing are removed from the lift using rolling movements. The work can also be done by resting your feet on the crosspiece and using rolling movements to remove the chair;

Detaching the seat from the cross and gas lift

1. disconnecting the lift from the piaster and crosspiece.

The work is done by knocking out the gas lift with a hammer with a rubber tip. To facilitate the process of disassembling the cross and the lift, you can also use a metal drift.

Before knocking out, remove the retaining ring - the pin located on the back side of the cross at the point where the gas cartridge is connected;

Removing the gas cartridge from the piastrum

1. installation of a new gas cartridge. To do this, at the first stage it is necessary to insert the device into the crosspiece (until there is a click indicating the fixation of the element), applying some force, put on the protective and decorative casing and connect the half-assembled structure with the piaster;
2. Assembling the computer chair in reverse order.

You can learn more about the independent process of replacing a gas elevator on a computer chair by watching the video.

Replacing a gas chair lift is not a complicated process, so even a novice craftsman can do the job on his own. If you have all the tools, a new lift and pre-processing, the work is completed within 15 - 20 minutes.

Computer chairs have long outgrown their status as exclusively office furniture. Today they are increasingly being purchased for apartments and houses, which is explained by the versatility, ergonomics and durability of the design. But even such reliable products can experience breakdowns, the most common of which are malfunctions in the gas spring. To find out the degree of wear of this part, you will have to figure out how to remove the gas lift from an office chair to repair it or completely replace it. You can cope with the task without professional help, the main thing is to know the features, the operating principle of this mechanism and strictly follow the instructions presented in the article .

DIY office chair repair: instructions with video

A modern office chair is a functional and comfortable piece of furniture, equipped with a rather complex mechanism that sooner or later fails. In such a situation, there are three options for the development of events: purchase a new one, take it to a specialized workshop, or repair the office chair yourself.

As practice has shown, it is quite possible to carry out such work on your own. The only thing that is required from the master is strict adherence to the sequence of actions and implementation of the instructions that will be given in this publication.

Types of office chairs

Today, there are three types of chairs on the office furniture market:

1. For a manager This piece of furniture usually has maximum capabilities: a five-beam steel cross; synchronization mechanism (a device that forces the seat and backrest to repeat the movements of the owner); mechanisms for adjusting backrest resistance, seat depth, negative tilt, etc.
2. For staff , furniture of this type has more modest characteristics and functionality. Most varieties are lightweight (ensuring high mobility) and are equipped with mechanisms for adjusting seat height, armrests, and back angle.
3. For visitors, Office chairs of this modification are simply beautiful, stable and comfortable furniture, devoid of any functionality. Often they do not even have a rotation mechanism and are produced on four legs, instead of one supporting leg with a cross on wheels.

Design features

Despite the variability of designs and functional content, almost all chairs consist of one set of elements:

• Five-beam cross (base). This part is made of metal or plastic. The first option is better quality and more expensive
• Rollers . Just like the crosspiece, the wheels can be made of metal or plastic. However, the mount and internal hinge of any roller are metal
• Pneumatic cartridge (gas lift). The part serves as the leg of the chair and is responsible for its “elasticity”
• The swing mechanism contributes to the axial deflection of the chair and its fixation in one position. On expensive models, a mechanism with an offset axis is installed, ensuring the smoothest swing possible.
• Piastra . This element is a metal platform with a lever. Serves to change the height of the seat relative to the cross
• Permanent contact is an element that connects the backrest to the seat and is responsible for changes in its position

Most office chair models have armrests. In cheap models, these elements are made of plastic; in more expensive ones - made of anodized or stainless steel.

Common breakdowns

As noted above, an office chair is a rather complex device and any of its structural elements can fail.

Damage to the cross

The problem with this element may be destruction at the junction of the beams. The material from which the cross is made is important here.

As a rule, the base is a hollow structure into which a polypropylene pipe of suitable size and cross-section can be inserted. It, in turn, must be rigidly fixed to the base and the damaged beam.

Plastic parts cannot be spliced ​​using glue or a soldering iron due to the large loads on the paws. There is no point in restoring the integrity of this element. The best option would be to completely replace the damaged structure with a glass-filled polyamide base.

In order to dismantle the crosspiece of an office chair, you need:

1. Remove the rollers . As a rule, they do not have a rigid fixation and are quite simply removed from the mounting sockets. To illustrate the process, it is recommended to watch the video:
2. Dismantle the piastra . Fastening to the seat is done “on a cone”. Disconnection from the gas elevator is carried out by tapping on the attachment point. The correct process for disassembling an office chair is shown in the video:
3. Remove the locking clip located in the recess on the top of the hydraulic lift.
4. Knock out the gas lift for repair or replacement of the five-beam.
   Note! In case of critical damage or destruction, it is impossible to knock the gas elevator out of the base. In this case, you should remove the working cylinder with the seal and bearing from the “glass”.

   The process technology and dismantling device are shown in the video:

Destruction of the swing mechanism

If the chair does not hold the “horizon”, then the problem is most likely in the destruction of the swing mechanism.

Fastening to the seat is done with four screws using a shaped screwdriver. The element is dismantled as follows:

1. The bolts that secure the rocking mechanism from the seat are unscrewed
2. The gas lift is knocked out of the device mount.

This element is made of metal.

You can independently solve the problem of a collapsed device by completely replacing it (recommended) or using a welding machine.

It should be noted that most chairs originating from the Middle Kingdom are not suitable for domestic spare parts. This concerns, first of all, the swing mechanisms (size discrepancy).

• Chinese mechanisms: 200 x 200 mm.
• Domestic: 200 x 150 mm.

In order not to re-drill holes when replacing an element, we suggest using adapter plates. How it looks assembled can be seen in the figure below.

Air chuck failure

The pneumatic cartridge of the chair is a two-chamber structure filled with air. When you press the adjustment lever, the valve stops the flow of air between the chambers.

If, when pressing on the valve, the gas lift rod does not extend, it means that the integrity of the piston, seal, etc. is compromised.

It is important to know! The gas lift cannot be disassembled . If damaged, a complete replacement of the element is required

The dismantling process is described above. To clarify the process, watch the video about replacing the gas cartridge on office chairs:

A fairly common cause of gas lift failure is the bending of the adjustment lever, which does not allow pressing on the cartridge valve. In this case, the repair can be easily carried out independently: you need to bend the lever to its original state.

If the contact is loose and the back does not “hold”, you will need to seal the connection. How to do this, watch the video:

What is gas lift in an office chair?

The design of such furniture is multi-component and complex, so it is not recommended to do the repair of office chairs yourself without first understanding their “stuffing”. So, the main task of the backrest is to support the spine of a sitting person. Its sizes and shapes may vary, but the angle between it and the seat is always about 90 degrees, which allows you to relax your lower back when leaning back.

The seat can be of several types, they are discussed in the table.

It is recommended to choose seats that have a rounded front edge. The width can vary from 40 to 50 cm, depth - up to 48 cm.

Armrests serve as a support for the elbows; with their help, the load is removed from the person’s spine and neck. These elements may be adjustable or non-adjustable. A piastra is a metal platform on which a lever is attached. Its function is to change the height of the seat. As for the gas lift itself, it is a steel cylinder filled with inactive gas. It adjusts the product in height, it can be long, medium and short. There is also a cross - a load-bearing component of the structure. It is a large-diameter base with rays, their optimal number is 5 pieces. It is the cross that bears the main load.

The crosspiece is made of metal or plastic - in the first version the chair itself will be heavier.

Rollers are used to move the computer chair. They are made from polymers, polyurethane or nylon. All these components are the main components of the design. In addition to them, manufacturers equip products with additional mechanisms that improve the functionality of office furniture.

Cause of clicking and troubleshooting

​

​

Sometimes, when leaning back, the chair begins to make characteristic clicking noises. The problem lies in the fastening of the structure. To get rid of clicking, lubricate the moving mechanical parts. If this does not help, the chairs need to be repaired. The workshop usually replaces the original washer. Sometimes the wheels can make clicking sounds. It is necessary to inspect all the wheels and clean them; it is better to replace broken parts.

Causes of failure

Computer chairs, when used correctly, last for many years. In the event of a manufacturing defect in the gas spring, the furniture can be replaced, especially if it has a warranty. But replacing the gas lift, either with your own hands or with the help of professionals, may also be necessary if the product is used incorrectly. Main causes of breakdowns:

1. Creating an advantage. It is not recommended to sit on one side of the seat; you need to sit in the middle.
2. Irregular furniture care. It is recommended to lubricate parts at the intervals specified in the instructions for use.
3. Frequent placement of two people on one chair. The structure can support a weight not exceeding 120 kilograms.

It is not recommended to sit down from a jump or run, otherwise there is a high probability of the gas spring breaking, as a result, you will have to change the gas lift on the office chair, which will entail additional financial costs.

Types of crosspieces for chairs

Before removing the crosspiece itself, you should take into account that the chair can be broken if you apply too much force (the gas cartridge is especially easy to damage). Therefore, we recommend viewing thematic lessons that tell you how to properly remove the cross from an office chair. The video describes the following actions:

• We remove the rollers from the unnecessary cross and disconnect the lifting mechanism from the chair. To “knock out” the lifting mechanism, you will need to make several blows with a hammer on the gas lift.
• Using a flat-head screwdriver, pry off the ring located in the center of the cross. There will be 5 protrusions on the ring that secure the plastic casing. You will need to bend the edges of the protrusions and carefully move the casing away. After this, the cross will be removed.

The next step is to replace the old product with a new one.

Replacing the mechanisms of a computer chair can be easily done at home. The video explains in detail how to change the crosspiece of office chairs. The replacement proceeds as follows:

• The plugs are removed from the steel body, after which new ones are installed inside.
• A casing is put on each “branch” of the cross, then the casings are secured with retaining rings to the center.

At the end, wheels are attached to the legs of the office chair and the product is connected to the gas lift.

If you don’t want to think about how to change the crosspiece in your office chair, we recommend looking at the Baltofis catalog and choosing reliable furniture.

An office chair is an integral part of any office. It is also used as a piece of home furniture. They must have a stable design, be light and comfortable. For ease of use, all chairs are equipped with a lifting mechanism. It rests on the crosspiece. Since the latter receives the greatest load, it is subject to wear and, as a result, may fail. To replace it, you can go to a workshop, or you can do it at home.

In order for a computer or office chair to last as long as possible without any breakdowns, it is necessary to care for it and follow certain rules.

• About once every six months you need to inspect all the furniture parts, check the tightness of the connections and whether all the nuts and bolts are tightly tightened;
• Fabric parts must be cleaned with a vacuum cleaner. If there are stains, you can use various stain removers;
• If the upholstery is made of leather, it must be wiped with a damp cloth soaked in a special solution;
• It is worth considering the maximum load of the chair used;
• There is no need to sit down suddenly on the seat to avoid breaking the crosspiece or gas lift;

If you follow the necessary recommendations, your office chair can last for many years.

The products differ in several aspects; let’s look at each of them in more detail.

Dimensions

Another important factor is the diameter of the mounting hole for attaching the wheels. There are only two varieties:

• 11 mm. The most common solution today, it is used in the vast majority of models and is available for sale in all furniture fittings stores. There are many design options, so you can easily select suitable rollers for any type of floor covering.
• 10 mm. This type of pin is much less common and is often used in wooden crosspieces and in designer models. In terms of its performance characteristics, this option is practically not inferior to the one described above, but in many regions there is a problem with purchasing such wheels, since they are bought very rarely, most sellers simply do not keep them in stock and carry them only to order.

The process of dismantling a part depending on the type of base

If the structure no longer rises and locks in the desired position, it means that the gas lift on the office chair needs to be repaired. You can do this yourself. The algorithm of actions will be almost identical for both plastic and metal bases.

Plastic

Dismantling of the structure, the base of which is plastic, occurs in a certain sequence. If a person is changing a gas cartridge for the first time and does not know how to remove the gas lift from office chairs, he will need an assistant. Instructions:

1. Unscrew the bolts located under the seat. Carefully remove it from the mountings.
2. Stand on the crosspiece and gradually, using rocking movements, pull the chair up by the armrests. Set it aside.
3. Use a rubber hammer to apply several light, precise blows to the body of the structure from the side of the cross - the gas lift should come out of the base gradually.

After this, you need to replace the part and perform the same steps in reverse order.

Metal

The principle of removing a gas spring from a metal base is similar to the previous one. The only difference is that some manufacturers use fragile material in the manufacture of the structure. Therefore, it is recommended to be careful when knocking out the gas lift. The blows should be weak so that the cross does not crack .

In fact, repairing an office chair gas lift with your own hands is a simple process. If you approach the solution to the problem responsibly and study all the nuances, you can repair the furniture yourself and very quickly, rather than spending money on a new product.

We are repairing a chair on wheels

This type of furniture is more susceptible to wear and tear than the same Soviet wooden chairs. Daily use quickly deteriorates the mechanisms and hydraulic parts that make up the structure.

But then another interesting question arises: why do some people’s chairs break down after two months, while others’ chairs last for years? Often this circumstance is due only to the quality of the materials of a particular model. First, of course, you need to pay attention to the fact that modern models can only withstand up to 130 kilograms, and the manufacturer provides a warranty of about 12-18 months.

But if it happens that the chair is broken, and the warranty card has not been valid for a long time, then with a little skill you can do the restoration work yourself.

Important! If you are not confident in your abilities, it is better to contact special service centers.

The problem and its solution

If it happens that the seat itself lowers when you try to sit comfortably, and rises synchronously with you, and this period of raising or lowering varies from one second to twenty-four hours, then the problem clearly lies in the gas escaping from the gas cartridge.

Important! The gas flits themselves cannot be repaired, since disassembling such a component can be hazardous.

In this case, you will have to take the damaged furniture, fix it in the most convenient position and begin replacing the old gas cartridge with a new one.

Important! The cost of such a part is low, which significantly reduces the cost of all work.

If you're still wondering how to fix an office chair, then you'll have to do a little preparation.
