Chair design

You can repair a computer chair yourself. To carry out high-quality furniture repairs, you need to know its design. Knowing the name of certain elements, you can easily purchase the necessary parts.

There are a number of models on the market today computer chairs. Structurally, they differ from each other. But despite this, their structural elements are the same. These include:

• cross with wheels;
• pneumatic cartridge or gas lift;
• permanent contact used to adjust the tilt of the chair back;
• armrests.

Modern models are equipped with a headrest, which improves the comfort of the furniture. Each of these elements, as a result of frequent use of a computer chair, withstands serious loads, which leads to their damage. If necessary, you can repair furniture and individual structural elements with your own hands.

Common breakdowns

The gas lift in computer chairs often breaks down. The device consists of two chambers that are filled with air. The mechanism is controlled by a lever that presses on the valve. The valve separates the chambers and prevents air from passing from one chamber to another. Thanks to this, the chair can change its height and be installed in a certain position.

If the pneumatic cartridge does not lock in the selected position, then this is due to its damage. Often, the failure of a pneumatic chuck is irreversible. The only way out of this situation is to replace the part. You can buy a spare gas lift in a store that specializes in such furniture. When performing mechanical repairs Special attention pay attention to eliminating piastres. It can be removed by physical force. Application great strength may damage the part.

It is not uncommon for the footrest rollers to break. In this case, the damaged element is replaced with a new one. Experts recommend changing all rollers. If desired, you can change the entire footrest. In this case, we are talking about replacing the entire crosspiece along with the rollers. It is best to pay attention to the products large diameter, which will improve the stability of the chair and extend its service life.

How to repair an office chair with your own hands: step-by-step instruction for repair

Modern office chairs are used both in offices and at home, and like any furniture, these devices, sooner or later, need repair. I offer an overview of the most common breakdowns and simple instructions to eliminate them.

Types of office chairs

Damage and breakdown of office furniture, as well as the complexity of repairs, are determined design features and operating features of a particular model. There is a wide range of office chairs on sale. What to choose taking into account the comfort of use, service life and subsequent maintainability?

Illustrations	Varieties and their descriptions
	Chairs for visitors. These are non-rotating models assembled on the basis of a metal frame. Seats and backs can be hard or soft. Soft models have foam filling and fabric or leatherette upholstery.
	Computer chairs (for staff). These are compact swivel models with a seat mounted on a roller base. The design uses rollers for soft or hard surfaces. This furniture provides seat height adjustment and backrest tilt adjustment.
	Executive chairs. In fact, this is also a computer chair, but with additional width and height of the backrest. The executive chairs use a rocking function with locking capabilities. Of course, there is the possibility of adjusting the seat height and tilt. Almost all executive chairs are soft and high-quality fabrics, leatherette or genuine leather are used as upholstery.

Advantages and disadvantages:

• Models for visitors are distinguished by such qualities as reliability, low cost and high maintainability. Despite the low level of comfort, such furniture is a good choice for equipping an office or home office under the condition of short-term work.
• Models for staff distinguished by comfort and functionality of use. But, due to the additional functionality, the design becomes more complicated, and therefore such chairs are more difficult to repair compared to the previous version, where there is simply nothing to break.
• Models for managers- this means even more comfort, useful and not so useful functions and even more luxury in decoration. All these advantages come at the cost of complex repairs.

Design features

The design of a simple model for visitors uses the following details:

• Tubular welded metal frame.
• Plastic or plywood seat and back.
• Fasteners for attaching the backrest and seat to the frame.

Foam rubber is glued over the seat and back and the upholstery is stretched.

More complex modifications of chairs are characterized by increased functionality, which is achieved through the use of a number of structural elements, such as:

• A cross with roller pairs allows you to roll relatively safely and comfortably on a flat floor.
• Gas lift is a mechanism responsible for changing the height of the seat.
• Mechanisms for changing the backrest and seat tilt.
• Mechanisms that block the seat rocking function.

Common breakdowns

Since the design of chairs for visitors is simple and there is nothing to break, we will focus on the most common breakdowns of functional chairs.

• Damage to the cross. The cross itself is a durable monolithic part that is difficult to break under normal use. More often, decorative plastic linings in the crosspiece break or wear out.
• Damage to rollers. In most chairs, if used incorrectly, the rollers crumble and break.
• Destruction of the swing mechanism. If the chair is used incorrectly, the locking mechanism in the swing mechanism stops working and it becomes simply unsafe to swing back.
• Air chuck failure. This is the most common failure, in which the compression in the pneumatic cartridge weakens and the rod with the attached seat falls down.

Causes of breakdowns

The causes of breakdowns are of two types, namely, non-compliance with operating rules and natural wear of parts. Let's take a closer look at the most common damage.

Illustrations	Damage and its description
	Crosspiece failures. The main reason is the impact and, as a result, the appearance of cracks in the decorative plastic linings. Due to the fact that feet are placed on the crosspiece, the inexpensive plastic of the pads quickly becomes covered with abrasions. On completely plastic crosses, due to heavy load, one or more beams break off right at the rod mount.
	Rollers. There are two types of rollers: hard for soft coverings and soft for hard surfaces. Most chairs are equipped by default with rollers for soft surfaces, which roll over tiles or parquet over time and begin to crumble and break. Also, due to heavy load, the roller rod may break off, as shown in the photo.
	Rocking mechanism. This unit fails due to excessive loads (large weight of the rider and intense rocking). The cheaper the chair you buy, the more likely it is that it is designed for light loads.
	Gas lift. The reason for the seat sagging lies in low compression, which in turn appears as a result of depressurization of the internal volume of the cartridge.

Self-repair - as far as possible

Almost any breakdown from the previously listed list can be repaired without going to a workshop. Moreover, to eliminate the listed problems, there will be enough tools that are probably available in any home workshop. Let's look at ways to troubleshoot the most common office chair problems.

Illustrations	Damage and remedies
	Cross. If the cross pads are broken, simply dismantle the broken part and try gluing or soldering it along the crack line. To hide the scuffs of the plastic covers, sand the entire crosspiece with sandpaper to a uniformly matte surface. If part of the all-plastic crosspiece is broken off, the structure can be bolted together through through hole, drilled in the rod. However, such a repair will not provide sufficient reliability, and therefore it is advisable to replace the crosspiece at the first opportunity.
	Rollers. If the wheel crumbles, the only thing the right way repair - its replacement. According to the type of fastening, there are two types of rollers: pressed into seats and models with a threaded rod. If the chair is Chinese, the roller rod is most likely pressed in. To remove the roller, place a chisel or other narrow metal plate into the slot at the base of the rod and pick out the part. In place of the removed roller, insert a part with the same rod.
	Rocking mechanism. If damaged, this unit is replaced as an assembly. You can find a replacement for a damaged part on the market or in online advertisements for the sale of chairs and spare parts for them. The mechanism is attached to the seat with four bolts. After the bolts are unscrewed, all that remains is to knock the faulty mechanism off the rod and press a new part in its place.
	Gas lift. Breaking this structural element eliminated by complete replacement of the part or restoration repair. Since such damage is not uncommon, let’s look at it in more detail.

How to remove a gas lift for repairs

In order to repair or change the gas cartridge, you need to get to it and this can be done in three ways.

How to separate the cross?

Here, too, you can’t do without a hammer. We turn the assembly over with the cross up and knock out the gas cartridge by striking the protrusion shown in the photo with a hammer.

The easiest way is to buy a new part and install it in place of the damaged element. After the replacement is completed, the entire structure is assembled in the reverse order.

Gas cartridge repair

Disassembly.

Remove the rubber gasket - limiter

Repair. After you have finished disassembling, you can replace or at least clean the rubber gasket, which does not fit tightly to the glass due to wear. At this point, you can replace the cage bearing. If the chair crunches when turning, the problem is precisely this part.

Reverse process (assembly). Assembling the gas lift is carried out like disassembling, but in the reverse order.

A simple and cheap way to repair a gas lift

Despite the fact that the proposed method is simple and cheap, it is effective. Of course, this method is suitable if only you use the chair and no one will try to change the height to suit their dimensions.

Let's sum it up

Now you know what types of damage are typical for office chairs and you can fix these damages. The video will reveal some nuances, and if during repair work If you have questions, ask them in the comments to the article.

Helpful advice

Common cause gas lift failure is that you are sitting on the chair incorrectly, that is, you are not distributing the weight over the entire area of ​​the seat, but are placing the main load on its front edge.

Manufacturers of office furniture prohibit the use of gas lift at temperatures below +5 degrees. With more low temperatures the liquid in it freezes, and under load it will immediately break. If you buy a chair in the cold season, then you can start assembling it only 24 hours after its components have been in a warm room.

• gas lift for chair

If the chair is so high that it is uncomfortable to sit on, it is advisable to shorten its legs. And some types of chairs and armchairs are designed in such a way that their height can be changed.

You will need

• - ruler;
• - thin indelible felt-tip pen;
• - saw or hacksaw;
• - file;
• - glue;
• - sandpaper;
• - nails and hammer;
• - chisel;
• - porous rubber.

Instructions

If you need to lower a chair that does not have height adjustments, first make sure it has expired. guarantee period. Then see if its design allows for shortening the legs. So, some chairs, for example, school ones, instead of three or four straight legs are equipped with two L-shaped ones. Their alteration is impossible. The same applies to products that have a single leg with a stand: having separated these parts from each other and shortened the leg, it is difficult to connect them again.

If the chair has three or four straight legs, first find out to what height each leg should be shortened. Then, using a ruler and a thin permanent marker, measure this distance on each of the legs, starting from the end. Do not take into account the thickness of the rubber or other soft pad. Using these marks as a guide, shorten metal legs with a hacksaw, and wooden ones with a saw. The cuts must be strictly perpendicular.

An office chair, also known as a computer chair, is now found not only in the office, but in every home. This furniture is very comfortable and you have to pay for comfort with problems. The chair has quite complex mechanism, which is subjected to considerable loads and often fails, it often requires adjustment or repair. This article will look at ways to repair an office chair with your own hands, without going to a workshop.

The most common parts to break are the rollers, the crosspiece and the gas lift. In the case of rollers big problems No. The easiest way out is to replace the broken roller with a new one or, if possible, glue it with superglue. Often the cause of the malfunction is debris: threads, hair, etc. Then it is enough to remove the rollers and clean the places where they are attached from clogging. If the wheel axle mounting socket turns out to be broken, you may have to replace the crosspiece.

Repairing the chair cross

Repairing the crosspiece of an office chair with your own hands is quite possible with some mechanical skills. To do this you will need simple tools and attentiveness.

The material of the crosspiece is important - if it is made of plastic, then it is better to install a new one. Plastic after repair serves even worse than new and restoring such a fragile part makes little sense. Pay attention to the type of plastic; it is better to replace the polyethylene cross with glass filled polyamide because this material is stronger and lasts longer than conventional plastics.

Disconnect the cross from the chair

To repair the crosspiece, you need to remove it and this process is not as simple as it seems. This often damages the part itself and the gas lift, especially if you use a hammer or sledgehammer. Be sure to use rollers because they are often damaged during disassembly and repair. Tool required:

• Hammer
• Kiyanka
• Screwdriver

It is better to cover the floor with rags or newspapers to protect it from grease. To disassemble tight connections, especially a gas cartridge with a cross, it is convenient to use WD-40, gasoline, or just soapy water. Attention! You can knock down a cross with a hammer only if it is metal; for a plastic one, you need to use a mallet. We recommend watching a video of an office chair repair.

Procedure

• We remove the wheels. Usually they do not have a rigid fixation and are easily removed from the mounts.
• We turn the chair over; for stability, you need to place it with the seat on the chair so that the back rests on the floor.
• It is necessary to disconnect the swing and adjustment mechanism - piastr. Unscrew the 4 screws securing it to the seat. Then you need to lightly tap it to knock it off the gas lift, since usually this is a non-threaded, conical connection. It is advisable to use wooden or rubber mallet and do not hit the edges of the parts, they are easily deformed. If the connection is “stuck”, you can use a special liquid or gently tap it with a hammer.
• Remove the gas cartridge stopper. The locking clip is located in the center of the cartridge recess; you need to carefully pry it with a screwdriver and remove it. Then you need to remove the washer and put it aside along with the clip. Now we disconnect the gas lift rod. Be careful! Inside the glass, gas lift parts may stick to the lubricant: 2 washers and an oil seal with a bearing. Set them aside and do not confuse them with the stop washer during assembly.
• We knock down the cross. You need to be especially careful with plastic ones. It is better to hit with a mallet or an ordinary hammer through a piece of wood, with light blows from all sides.

This work must be done extremely carefully and carefully; with careless work by a non-professional, the piastre and gas cartridge often break.

To reassemble you need to do everything in reverse order.

• Repairing the crosspiece of an office chair itself does not always make sense if it is plastic. Glue and soldering with a special soldering iron for plastics do not provide strength; they can only be used to seal small cracks.
• You can attach a broken leg of the cross using a metal or plastic overlay. Sometimes a plastic tube of suitable diameter is used for this and secured with glue or screws.
• For broken or cracked metal crosspieces the best option- welding.

Fixing a gas lift in an office chair

Repairing the gas lift of an office chair with your own hands will help you save a considerable amount on the services of a specialist or buying a new thing. In this case, it is necessary to clearly determine the cause and severity of the malfunction; in many cases, the easiest way is to replace the entire cartridge. The part is not cheap, but New furniture much more expensive.

When the chair starts to fall down randomly and the lift lever does not work, these are clear signs of a gas cartridge failure. Let's check it like this:

• You need to unscrew the seat and see if the lever presses the gas cartridge valve. In a working mechanism, when pressure is applied, the valve goes down and the gas cartridge moves out.
• The problem sometimes lies in a bent lift arm. Then you can carefully straighten it to its original state.

To repair or replace a gas elevator, you need to completely disassemble the chair. The process is described in the first part of the article (repairing the crosspiece of an office chair). Installing a new part is much easier than removing a broken one, the main thing is that you don’t need to hit it with a hammer.

Gas lift repair method

• You need to determine the optimal chair height for you. Measure and record the result.
• You need to remove the crosspiece and disconnect the cartridge from the piastrum, having first unscrewed the seat.
• Then the glass is removed and the parts are sequentially removed: washers, bearings, etc. It is important not to lose them and remember the installation order.
• Then you need to select a tube or rigid hose made of plastic that fits the axis of the elevator internal diameter. The tube will have to be cut to the chair height that is comfortable for you (this was done in the first step). For this purpose, you can use a water pipe made of metallized plastic.
• The resulting part is put on the rod and all parts of the cartridge are installed in the reverse order.

After assembly, the chair should behave normally. This method will help restore the minimal performance of the chair and prevent “failures”, but the gas lift will no longer work like new. In general, replacing it completely is the best option; for cheap and mid-priced chairs, the costs for this spare part will not be high.

High-quality work furniture allows long time be in a sitting position without feeling tired. Comfortable tables, work chairs, sofas and paper racks sooner or later fail. A simple work chair is also office furniture Irkutsk, which is used along with a table. No matter how durable the chair is, at some point it may break.

How to fix an office chair?

Most faults can be easily fixed by specialized workshops. But there are very few of them, and also fewer specialists ready to go to the client’s office. Therefore, you should learn to independently identify and repair office chair breakdowns.

Among the most common are:

1. The gas lift foot (the gas-lubricating shock absorber that regulates the height of the chair) does not work.

Possible breakdowns:

• the gas lift itself is damaged;
• piastres foot is broken;
• the swing mechanism (if any) is damaged;
• the multiblock, which fixes the backrest in a stationary state, is jammed;
• technical error in the initial installation of the armrests or piastres fastening.

If relaxing the multiblock or rearranging the fasteners does not help, then you cannot do without a specialist.

2. The back of the chair is not fixed.

Check the integrity of the permanent that connects the seat and backrest.

3. Significant back play when all clamps and fastenings are fully secured.

Most likely, due to prolonged loads, the fastening system broke. It is also possible that the fastening of the backrest and permanent was bent.

4. Large seat play.

Among the main reasons may be a broken swing mechanism (if any), a damaged gas lift, or a broken piastra mount. This type of damage occurs most often among those who like to “ride” a chair around the office. The only fix may be complete replacement gas lift.

5. Rollers falling out.

Due to prolonged loading, the retaining rings have burst, the plug for securing them has worn out, or the roller itself has failed. There is only one “treatment” option - replacing the rollers.

Pay attention to the amount of damage your chair has. If there are more than two of them, then the repair is not cost-effective. However, if it breaks down due to a defect in one of the components, taking the chair to a specialist is a good solution.
