How to repair a computer chair

Many office workers use the computer chair. This can be attributed to convenience and high performance. Often this furniture is also used at home when decorating a workplace. Over time, any structure wears out, so you need to know how to fix a computer chair with your own hands. To do this, you will need to use the recommendations and instructions of specialists.

If you use a seat like this for a long time, it breaks. Most often, the trigger mechanism deteriorates. Seat height not lowered or raised enough. This raises many problems that make the product less convenient for everyday use. In this case, you need to take appropriate action to eliminate the defect. For this, it is better to contact specialists.

You can fix the furniture yourself. To do this, it is necessary to determine the source of the problem, as well as to understand the basic structure of the furniture. It is recommended that you study all the diagrams. If you cannot do something on your own, it is better to entrust the task to someone more experienced.

Design features of the computer chair

Do-it-yourself office chair repair requires certain knowledge. There are many things to consider when buying furniture. You should not buy products where the manufacturer does not give a guarantee for at least a year and a half. Otherwise, you will have to constantly repair the product, which will cause significant difficulties.

Note! After the expiration of the warranty period, the likelihood of breakdown increases. It is necessary to understand what caused the failure of a certain part. This will help you avoid unnecessary hassle. The causes of malfunctions can be different. The sooner the problem is identified, the faster the home repair will go.

Structurally, the product consists of several elements: backrest, seat, cross section with rollers for movement on the floor. If any of these components fail, the chair cannot be used. It is required to repair the damage in order to continue to operate the furniture normally.

The product includes the following components:

• Piastra. Made from high quality metal. This element is produced in the form of a lever. Used to change the height of the seat relative to other components.
• Rollers. Depending on the manufacturer, they can be made of metal or plastic. The first option is more preferable, since it has high performance properties. The swivel mount is made of metal.It connects to the main structure to provide movement on a smooth floor surface.
• Base. It can be metal or plastic. The first option is more preferable, since it has high strength and reliability compared to plastic. The latter breaks down faster under the influence of high physical exertion.
• Permanent contact. It is a connecting component. Used to attach the seat and backrest. Allows you to change the position of the backrest relative to the vertical.
• Swing mechanism. Responsible for deflection and fixing the seat in one position. More expensive models are equipped with sophisticated mechanisms that provide a more stable fixation and smoother swing when leaning against the back of the seat.
• Gas lift. This detail is essential for a computer chair. Responsible for elasticity. When a part breaks, this property is reduced, which causes discomfort for the wearer.

Note! Most of the modern products are also equipped with armrests. Depending on the cost of the model, the material of manufacture of the part may differ: plastic or anodized steel.

Parts may be required for replacement. They can be purchased at specialized stores. You can also purchase spare parts on the manufacturer's official website. It is for this reason that it is recommended to buy only furniture from trusted companies. This makes it possible to repair the product with minimal costs, using available tools and simple tools that are in every home.

What is office chair gas lift

This part is a hydraulic gas control system. It is an intermediate and main component that is responsible for the multifunctionality of the chair.

Important! If there is no experience of replacement, you should learn how to repair the gas lift of the seat. The instructions must be followed carefully. Otherwise, it is better to entrust the task to a specialist who has extensive experience in performing such tasks.

Externally, a pneumatic device looks like a tube. Two elements with different diameters are suitable for it. It also has several key components:

• Gas valve. Responsible for maintaining a uniform seating position. It can be used to set the desired seat height. It is activated only at the moment when it is necessary to change the position of the seat.
• Sealant. Individual parts that are responsible for the tightness of the entire structure.
• Button. It is located in the inner part of the tube of the pneumatic device. When pressed, the chair rises or falls - the gas valve opening mechanism is activated.
• Cavity. This element is also used to activate the seat change mechanism.
• Bearing. This component is responsible for the rotation of the chair around its axis. Provides smooth position change.
• Stock. Appears depending on seating position and height.

This design is irreplaceable as it increases the performance of the computer chair. In particular, such a chair is convenient for use by several people of different sizes.

Other reasons for using a gas lift include:

• Easy seat adjustment. To change the height of the chair, just press one button. There is no need to perform any complex manipulations.
• Increased comfort. The chair reduces the load on the spine and back, which allows you to constantly sit in the same position and maintain posture. This option is responsible for depreciation.
• Rotation. This system allows you to rotate the chair in a circle without unnecessary effort. All movements are simplified as much as possible for the convenience of users.

All the capabilities of computer chairs are determined by the presence of a gas lift. It is also important to properly distribute the load. Otherwise, a quick breakdown of the main structural units is possible.

Common breakdowns

Before you repair the office chair gas lift, you need to find out the main causes of the malfunction. Among the main breakdowns, the following should be highlighted:

• The chair seat does not rise or fall. The problem is that the position adjustment lever has broken. The pressure on the button is too high, causing a problem.
• Instability. The swing mechanism is out of order. The gas lift could break, resulting in a loss of stamina.
• Violation of the movement of the wheels. It breaks when the inner part of the wheel mount wears out. The integrity of the bushing is compromised.
• Skew. The seat attachment mechanism is worn out. It can also occur in case of fatal errors during the assembly process.
• Difficulties in fixing the back of the chair in one position. Wear on the backrest and seat attachment is observed.

If any of the listed symptoms occur, inspection and repair is required. Otherwise, the use of a chair threatens injury.

How to disassemble

It is necessary to be able to repair an office chair yourself, as it is not always possible to contact the service center for the help of specialists. To disassemble the structure, it is necessary to understand in general terms the location of the main structural elements of the product.

To do this, you need to perform the following actions:

1. Turn the furniture so that the back is turned to the wall. Press down on the crosspiece without using too much force.
2. Gently rotate and swing the backrest attachment mechanism
3. Separate the hydraulic gas device and the cross section.
4. Unscrew each wheel from the crosspiece.

It is important to properly separate the back and seat. The integrity of the furniture depends on this. After the preparation has been completed, it is necessary to collect all the parts so as not to lose.

Note! Do not use too much force when disassembling the chair. Otherwise, you risk breaking the fragile plastic under pressure.

To detach the hydraulic gas device without undue effort, the pneumatic chuck can be turned over. After that, it is enough to pry and remove the part with a few gentle movements.

Office chair repair

After the disassembly has been completed, you can start repair work. Depending on the type of breakdown, the range of tasks performed will differ. It is important to follow the manufacturer's instructions carefully so as not to aggravate the problem.

Replacing the feet

Such a breakdown occurs most often, since the main load is applied to this mechanism. To carry out replacement or repair, it is enough to carefully remove the part from the mount. It can be removed easily enough, for this you need to press on it with pressure. After that, a new part is installed.

Replacing the crosspiece

The repair of the cross is a responsible task, on which the operational capabilities of the chair depend.To increase the tightness, a hollow tube of a smaller diameter is inserted into the mechanism. After that, it is tightly fixed inside.

Air chuck breakage

The hydraulic gas device can be replaced with a new one. You can repair it, but after that the element will not last long. When installing a new product, be careful not to damage the base.

Destruction of the swing mechanism

If this mechanism breaks down, it is necessary to replace the metal part. This requires disassembling the component with a screwdriver. First, the bolts for fastening to the chair are removed, after which the element is removed from the pneumatic chuck.

To perform the described manipulations, you will need a drill. It makes it much easier to create new holes for mounting the swing mechanism. If you do not have a drill, adapter plates are available. When choosing a spare part, it should be borne in mind that the dimensions are different for each model.

Operating tips

A computer chair requires careful handling. This is especially true for an already repaired device. When using, you should adhere to certain rules so as not to break the furniture. Otherwise, the service life of the device will be greatly reduced. The following recommendations of specialists should be taken into account:

• It is not recommended to use the products in rooms with a high level of air humidity, as this quickly destroys the integrity of the mechanism.
• If the furniture was delivered at low temperatures, it is forbidden to assemble it immediately after placing it in a warm room. It is better to start installation the next day in order to avoid violating the integrity of the structure.
• Do not put pressure on the bolts and the main fasteners of the structure. Plastic does not withstand high mechanical stress.
• Do not put a heavy load on the crosspiece.

Note! Children should not be allowed on office chairs for games. Because of this, the main mechanisms quickly wear out.

Several people cannot sit on a chair at the same time. Also, do not forget about the fragility of the armrests. With excessive pressure, they quickly deteriorate. In many models, the fabric is also vulnerable to dust and dirt. Vacuum frequently to avoid dirty build-up.

An office chair is a comfortable and practical piece of furniture. To make it last longer, you need to follow the basic principles. Replacing parts in a timely manner will help extend the life of your device.
