Structural elements and common breakdowns
Do not buy furniture for home and office if the manufacturer gives a guarantee of less than a year and a half. Practice shows that such products quickly fail. If after the warranty period the furniture begins to perform its basic functions poorly, you must first find out the causes of the malfunction. They may be different. The most common problems are described in the table below. When it’s known that it’s broken, it’s easier to plan and carry out repairs.
| Malfunction | Cause of the problem |
| The seat does not rise or fall | The tip of the lever that presses the gas lift button is bent or broken |
| Wheel problems | The sleeve is broken, the snap ring is missing |
| Swing the chair one way or another when sitting | The fasteners are loosely tightened, the back mechanism is worn, production errors |
| The back is loose, it is difficult to fix it in a fixed position | Permanent contact is worn - an element connecting the seat to the support |
| The chair became unstable | Gas lift out of order, rocking mechanism broken |
The main structural elements of the product: seat, back and cross with rollers. If at least one part of the general mechanism fails, the chair cannot be operated until the malfunction is completely eliminated. Repair may require additional parts to replace broken or worn parts. They can be found in service centers or ordered in the online store from the furniture manufacturer. You can also find out how to repair a chair with your own hands at minimal cost.
To facilitate self-repair, it is recommended to choose office furniture of domestic production. Armchairs from foreign manufacturers are of good quality and have a long service life, but in case of a malfunction, it is very difficult to get spare parts. Not all furniture companies in Europe have official representatives in Russia.
Self-disassembling the product
Each user should know how to fix an office chair. It is not difficult to disassemble the product yourself, for this, basic knowledge about the design is enough. Practical dismantling skills may be needed for both repair and disassembled furniture.In order to prepare the chair for repair, you must:
- Turn the furniture back against the wall, carefully stand with your feet on the horizontal crossbar of the crosspiece, while not pushing it hard.
- Gently pull the back up, swinging it to the right and left.
- Separate the spider and gas lift.
- Screw all wheels.
The most crucial stage is the separation of the back and seat. Having completed the dismantling, it is necessary to collect all the details in one place so as not to lose anything. If something does not work out, you can’t make physical effort: the plastic parts can easily break from one careless movement.
If you want to effortlessly separate the gas lift from the rest of the structure, you can install the seat so that the air cartridge is at the top. After that, you need to take a hammer and gently hit it on the seat where the back is attached. Next, repeat the same in other places so that the mechanism raising (lowering) the chair does not jam.
These manipulations should be carried out on weight so as not to break fragile plastic fragments. If everything is done correctly, the part will smoothly lower.
Computer chair repair has a clear algorithm. Any office chair, regardless of cost and appearance, has a standard structure. It is clearly visible in the diagram in the operating instructions. The following elements can be distinguished in the design:
- A metal or plastic base is a cross, or a five-ray base, resembling a star in shape.
- Plastic rollers with a metal hinge inside. More expensive models have iron wheels.
- Pneumatic chuck. In some operating instructions, this part is also called a gas lift.
- Swing mechanism with a straight or slightly offset axis.
- Piastra, or height adjuster. It is a metal platform equipped with an additional lever.
To connect the seat to the back, the so-called permanent contact is used. Almost all models of armchairs are equipped with armrests.
The most difficult thing is to repair furniture for managers. These are the most expensive seat modifications with many additional features. Products designed for staff are much simpler. The cheapest furniture is made for office visitors. It, as a rule, does not last long and cannot be repaired. Instead of a cross, these chairs have four legs, and a rotating mechanism is not provided.
DIY repair
In the event of failure of the cross and permanent contact, these parts can be repaired independently without resorting to the services of a service center. If the pneumatic cartridge, piastra or swing mechanism breaks, they must be replaced. The same goes for videos. If self-repairing seems difficult, you can turn to specialists, they will repair furniture quickly and efficiently.
Crosspiece damage and roller replacement
In the event of such a breakdown, it is very easy to repair an office chair with your own hands. If the rays of the cross are not connected firmly, the part begins to stagger and loses stability. To eliminate the malfunction, you need to insert a hollow tube made of plastic of smaller diameter into the base. It must be tightly fixed in the center of the structure.
The pipe will play the role of a kind of rod on which the base rests. To replace worn rollers, you need to carefully remove them from the sockets without applying physical effort, and put in new ones. Anyone who repaired the base knows that it’s not at all difficult.
Crashed piastres
For office chairs, such a breakdown occurs frequently. If the piastra is out of order, it must be carefully removed from the pneumatic cartridge. These two parts are connected by a conical method. There is no thread, so no screwdriver is needed. To separate the gas lift and the piastra, you should forcefully hit them with a mallet. As a rule, one hit is enough.Next, replace the piastre with a broken foot with a new one.
The destruction of the swing mechanism
In the event of such a breakdown, the metal structural element must be replaced. However, if you have a welding machine, you can eliminate the malfunction, and the swing mechanism will last a long time. If a decision is made to replace a part, it must be dismantled. The mechanism is connected to the seat with four screws, so you need a curly screwdriver. To disassemble it is necessary:
- unscrew the bolts connecting the mechanism with the seat of the chair;
- knock out the pneumatic cartridge from the mount;
- drill holes in the element and replace it.
If there is no drill at hand, you can use the so-called adapter plates. It should be borne in mind that Russian-made swing mechanisms are not suitable for Chinese office furniture. The difference in size is approximately 50 mm.
Pneumatic cartridge breakage
An old, worn gas lift must be replaced. Some craftsmen repair it, but after repair, the pneumatic cartridge will still not last long. It must be dismantled and replaced with a new one. To do this, disconnect the seat and use a hammer to knock out the gas lift from the cross. The main thing is not to damage the base. After that, insert a new pneumatic cartridge. It is mounted on old bolts. You can pre-watch a video on the topic "repair gas lift" or consult a service center.
Destruction of Permanent Contact
Permanent contact failure is a common occurrence. It is not necessary to purchase a new part; you can repair the old one. This type of repair of office chairs with your own hands will not take much time and effort. The main thing is to identify the cause of the malfunction.
If the thrust spring is deformed, it must be returned to its original shape. The same goes for brackets. However, if screw fasteners are frayed, you will have to replace them with new ones. If the back of the chair is staggering, the permanent-contact joints must be sealed - tighten more tightly.
Operation tips
An office chair, especially a refurbished one, is a rather fragile and vulnerable design. During operation, it is recommended to strictly adhere to the instructions. If you ignore the existing rules, the shelf life of the product will be significantly reduced. To furniture in the office served for a long time, you must keep in mind the following points:
- It is not recommended to use chairs in a room with high humidity.
- If the furniture was brought into the office or apartment from the cold, you can not immediately proceed to assembly, because fragile plastic parts are very sensitive to temperature extremes. It is better to start installation at least in a day.
- Do not press on the bolts during assembly, otherwise the nut may fall under the trim and you will have to dismantle the seat in search of a fastener.
- It is forbidden to exceed the permissible load on the rollers and crosspiece.
You can not sit on a chair together, otherwise the base of the product may break. For employees with a lot of weight, it is recommended to choose chairs with a metal cross: it is stronger and more reliable than plastic. It is strictly forbidden to fall onto the seat in a big way.
Keep in mind the fragility of the armrests. In no case should you sit on them. Experts recommend tightening all mounting bolts once a quarter so that they do not loosen over time. You should not use the seat to transport heavy objects, this quickly spoils the upholstery and the mechanisms fail. You can not carry a chair on the floor if it is covered with tiles: when the rollers fall into the joints between its fragments, this leads to quick wear.
In computer chairs, the fabric is quite vulnerable to external influences.The seat and backrest must be vacuumed weekly so that dust does not accumulate on them. In the event of stubborn stains, only the products recommended in the instruction manual may be used. It is strictly forbidden to use folk methods.
Children should not be allowed to play in the office chair for entertainment. From this, the rollers and the cross quickly wear out, and this also reduces the shelf life of the swing mechanism.
In order for the chair to last for a long time and not break, it is necessary to strictly observe the operating requirements. If the warranty on the piece of furniture has already expired, the simplest repair work can be done independently. The success of the repair depends on the complexity of the breakdown, as well as on the quality of the parts selected to fix the malfunction.
