Modern office furniture is so thoughtfully designed that even long hours of work at the computer are comfortable. But sometimes during constant use certain inconveniences arise, for example, creaking. This unbearable sound is not only annoying, but also leads to a decrease in performance. If a similar problem occurs in an office or enterprise, they usually call a specialist, but at home this service is not available to everyone. This article will tell you why computer and office chairs squeak and what to do first. Eliminating trouble with your own hands is not so difficult, and a basic set of tools necessary for all manipulations can be found in every home.

Causes of squeaking

Office furniture has a complex design. In addition to the frame of the back and seat, it has several moving mechanisms. Therefore, it can creak for various reasons. Even a new product sometimes makes strange sounds immediately after purchase, which is often due to improper assembly or poorly tightened screws - this is a common reason for a computer chair to squeak .

There is no need to rush to return the product to the store; the nasty squeak can be eliminated by tightly tightening all the bolts.

Furniture often begins to make annoying sounds even after prolonged use. There may be several reasons why the computer chair began to creak:

• the bolts are loose;
• one of the parts has worn out;
• the swing mechanism has failed;
• gas lift broke down;
• the weld of the piastres burst;
• The grease has dried out.

Most often, an office chair squeaks because the bolts are not tightened properly, or the lubricant on the moving mechanisms has dried out. Sometimes it can make such sounds when a person just sits on it. But more often, a computer chair creaks when rocking or turning. Traditionally, sounds come from under the seat or backrest.

If creaking is heard in the lower part, the gas lift is most likely broken. This is a shock absorber that is needed to ensure that the seat is comfortable and can be raised or lowered. Breakage of an element often occurs among those who sit down abruptly or swing on such furniture. After finding out the main causes of the malfunction, it will not be difficult to understand what to do if the office chair squeaks.

How to disassemble and repair

Repairing a computer chair yourself is not that difficult. To do this you need:

1. Unscrew the adjusting screw.
2. Remove the backrest from the guide.
3. Unscrew the bolts and remove the L-shaped fastener.
4. Remove the plastic corners using a screwdriver, carefully bending the latches.
5. Disassemble the mechanism, clean it from dust, lubricate it.
6. Reinstall the L-shaped device.
7. Remove the four screws to disconnect the seat from the leg.
8. Clean from dirt.
9. Clean and lubricate the bearing located at the bottom of the leg.
10. Disassemble the backrest by removing the decorative casing, unscrewing the screws and sliding it out of the locks.
11. Lubricate all parts and replace if necessary.
12. Assemble the chair.

As a result of consistent actions, you can not only get rid of the unpleasant creaking of a computer chair, but also repair and replace parts and fasteners that have failed.

Necessary tools for repair

To repair a computer chair and eliminate unwanted sounds, you will need the following tools:

• screwdrivers - Phillips and straight;
• hexagon;
• pliers;
• hammer;
• special furniture lubricant;
• spare accessories.

Most often, there is no need to change any parts of the chair; they break very rarely. The entire repair will consist of lubricating the mechanism or tightening the bolts. For lubrication, it is best to use WD-40 spray. If you don’t have it at hand, or the product doesn’t help, you can use any oil lubricant or even regular Vaseline.

Sometimes repairs may require thread sealant or PVA construction adhesive.

What is a gas lift for an office chair?

A gas lift or gas cartridge is a mechanism that is responsible for adjusting the height of the seat surface and allows you to fix it in a position convenient for use.

The main elements of the gas cartridge: cylinder and spindle.

To ensure that your device serves you for many years, we recommend following these steps:

• - do not jump on the chair;
• - once every few months, lubricate the elements of the chair with special oil;
• - under no circumstances should you sit in a chair together and create an advantage;

Causes of gas cartridge failure:

• — not careful handling of the office chair;
• — the user’s weight exceeds the permissible weight for operation;
• — the warranty period has expired;
• — the user sits on the chair from a jump;
• - rocking in a chair when the mechanism is in a fixed position.

If your chair's warranty period has expired and a breakdown occurs, then having certain knowledge, you can make repairs at home.

If you sit down on a chair, and it independently changes the position of the seat down, and after a while returns to its place, this is one of the signs of a breakdown of the gas cartridge. In this situation, you can fix the position of the chair using improvised means or replace the gas lift.

In order to replace the gas cartridge, you will need:

• - armchair;
• - screwdriver;
• - rubber hammer;
• - metal drift;
• — a new gas cartridge, suitable in diameter and length;
• - vice.

Progress:

1. -If you carry out repairs in the cold season, the liquid in the gas cartridge may freeze; it is prohibited to use it. You must wait until the new gas lift reaches room temperature.
2. — Next, use a shaped screwdriver to unscrew the seat from the piastres.
3. — Turn the chair over and make a mark on the face of the rocking unit.

4. — Then unscrew the four screws that secure the chair with the rocking mechanism.
5. — Now we dismantle the protective casing.
6. — using a rubber hammer, tap the swing mechanism at the base of the gas lift with gentle blows.
7. - now knock the gas cartridge out of the crosspiece.
8. - then turn the crosspiece over with the rollers up, and using a metal drift, delivering precise blows, knock out the gas cartridge from the cone base of the crosspiece.

Now you have to do the reverse process - assembly:

• — We screw the swing mechanism to the backrest seat.
• — Then place the crosspiece with its wheels on the floor, and then remove the transport cap from the new gas cartridge.
• Important: do not press the gas cartridge button in your hands, this is dangerous to your health!
• — now we are installing a new gas lift, make sure that the diameter of the gas cartridge completely coincides with the cross.
• — now we put on the protective cover, and then the chair body on the swing mechanism.
• — we press our hands on the body of the chair, check all the elements and sit down in the chair to check the operation of the new gas cartridge.

Helpful Tips:

1. - if you have assembled a new chair, and you immediately have problems with the gas cartridge. There is a high probability that the gas lift is in poor condition or defective. But it is also possible that the gas cartridge button can be fixed with a lever from the swing mechanism.
2. - if the gas lift does not respond when you press the lever, make sure that the piastres or the swing system are secured correctly, as well as the integrity of the lever for pressing the button.

If the above reasons are absent, the gas lift needs to be replaced.

Fixing the defect yourself

After prolonged use, users notice that the chair begins to make grinding noises and other unpleasant sounds. What to do if your computer office chair squeaks depends on the root cause:

1. Most often the problem occurs when bolts are loosened. To correct the situation, you need to turn the chair over and, depending on its model, use a screwdriver or hexagon to tighten all the fasteners until they stop. If some of them scroll, you will need to remove the element, pour sealant or PVA into the hole and quickly screw the bolt back. After this, you cannot turn the chair over, much less use it, until the glue is completely dry.
2. To figure out why the back of an office chair creaks, you need to remove it. This is easy to do: unscrew the screw and, lifting the element up along the guides, pull it out. After this, you will need to remove the plastic trim from the back in the same way. The plywood frame has metal plates secured with bolts. All of them must be checked and screwed well. If necessary, gaskets or sealant can be used. In addition, it is recommended to clean the backrest from dust.
3. Quite often the swing mechanism of an office chair creaks. You can get to it after removing the backrest. At the point where it connects to the seat there is an L-shaped mechanism responsible for tilting. Dust also collects there, so a squeaking sound may be heard when swinging. The mechanism can be easily disassembled by removing it from the case, but it is important to remember the assembly order. After dismantling, it is cleaned of dirt and lubricated. To assemble furniture, all steps are performed in reverse order.
4. A computer chair often creaks due to the drying of the lubricant that covers all the moving parts of such furniture. This substance is short-lived, sometimes it dries out in the warehouse, so even a new product can make a squeaking noise. Therefore, it would be useful for any user to know how to lubricate an office chair so that it does not squeak. For this purpose, you can use any lubricant except grease. It is very convenient to use a special product in a can. It is best to first disassemble the mechanism, wipe it from dust and remnants of old lubricant, and only then apply a new layer of it. You don't have to completely disassemble the chair to do this. If the lubricant is in a can, you just need to spray it on all problem areas. But often this is not enough, since dust and dirt accumulate inside during operation.
5. If the chair squeaks when turning, the problem is in the bearing located at the bottom. Lubricating it is very simple: to do this, you need to turn the chair over, remove the latch and the washer holding the gas lift in the middle of the cross. After this, you can easily pull out the cross, exposing the gas lift mechanism. There is no need to disassemble it anymore, it is better to wipe and lubricate it like this. If the device fails, it must be completely replaced.

The instructions for any office furniture indicate that lubrication and checking of the mechanism, as well as tightening of connecting elements, should be carried out every six months.

A computer chair is a very useful thing for working in the office and at home. However, it happens that favorite pieces of furniture begin to fail. From this article, you learned how and with what to lubricate the chair so that it does not creak, which means you now have an understanding of how you can significantly extend the operation of the mechanism.

Prevention

In order not to search on numerous sites and ask friends what to do if your computer or office chair creaks, it is better to prevent this problem in advance. It is wrong to neglect the rules for operating such furniture, believing that it is made reliably, and if something is wrong, then the manufacturer is to blame .

You need to know how to use chairs with moving parts correctly:

1. They should not be ridden unnecessarily, rocked or tilted too far back. You should also not spin around in your chair like on a carousel.
2. It is important to remember that there are weight limits that such furniture can withstand, so obese people need to choose special, stronger models.

If you don’t sit down in the chair from a running start, don’t swing on it and don’t overload it, you won’t have to think about how to repair it later. In addition, it is very important to regularly lubricate and inspect all mechanisms, tighten bolts and clean dust - then the product will serve for a long time and without failures.

An office chair squeaks, how to lubricate it

If the chair begins to make an unpleasant sound and squeak unpleasantly, then it’s time to properly inspect it. Many reasons can be easily corrected with your own hands at home. First, listen and determine what the sound is like and the approximate source. Creaking, grinding, clanging, clicking? The last two options mean that the bearing between the crosspiece and the gas lift may have burst. In this case, you will have to completely change the gas lift.

The main reasons for an office chair squeaking:

• put together very poorly;
• Parts need to be replaced;
• the seams in one of the mechanisms burst;
• The bolts have become loose.

First, let's look at the structure of the design and mechanisms of the chair. Often the problem lies precisely in the moving parts that are responsible for adjusting the height, tilt and depth.

First of all, you need to check the frame: whether the bolts are tightened well, how securely the fasteners fit, whether they are all in the right places. Check out the following places:

• armrests (including covers);
• swing mechanism;
• fastening the backrest to the seat;
• cross.

Just don't tighten the bolts too much, otherwise you'll strip the threads. If you can no longer secure it, use thread sealant.

What to do if a squeak appears?

Loose and creaking furniture can last for a long time if the cause of the problems is removed. To do this, you need to carry out a small repair of a wooden chair with a backrest, which does not require special equipment.

First you need to determine where the squeak appears. This may be play in the slats or crossbars at the attachment points. To eliminate the defect, it is necessary to replace loose nails or introduce glue into the gap.

If the squeak remains, you will need to disassemble the product and remove the loose fasteners. All grooves and tenons need to be treated with glue, then assembled and allowed to dry completely.

Step by step stool lubrication

In order to begin the lubrication process, you first need to disassemble the chair.

1. The soft part of the seat is removed.
2. All movable parts of the height adjustment are treated with liquid.
3. In addition to the mechanism, you also need to clean the fasteners of the chair.
4. After the seat is processed, you can move on to the back.
5. The back of the chair is removed after unscrewing the bolts or screws. When all parts are removed, the rubbing surfaces are processed.
6. If the chair provides for the use of wheels, then they are also treated with a solution.

The process of lubricating a chair is not complicated and you can do everything yourself, but if you have absolutely no time, you should entrust the work to professionals who will do everything not only efficiently, but also as quickly as possible.

Nowadays, you can order office furniture repairs online, and you don’t even have to leave your home. After submitting your application, a specialist will contact you and clarify the reasons for the malfunction. At the agreed time and address, a master arrives and carries out repairs, after which the chair becomes like new. If something breaks during operation, the technician can replace the part with a new one.

“The computer chair creaks.” “The chair began to creak, no matter how much I lubricated it.” “How to prevent an office chair from squeaking.” “My office chair is creaking, I’m already tired of it. ", "Not even a few days passed, a squeak appeared, we are not happy with the purchase."

These kinds of posts often appear on forums and in reviews about chairs. Every buyer believes that after purchase his chair should work without flaws, and if there is any hint of a malfunction, then the seller must be held responsible. Today we will try to look at the “malfunctions” of the chair, which can be corrected without much difficulty at home.

The first thing that can creak is the frame of the chair itself. After carefully reading the warranty card, you can find the following standard clause in the operating rules: “Check the mechanisms, tighten the fasteners and fixing elements of the chair every six months.” But even with a fresh assembly, loose bolts are not that uncommon.

It should also be taken into account that all fasteners will fit into place only when used under load. Therefore, a hexagon or Phillips screwdriver, depending on the model of the chair, will help tighten all the fastening bolts in a couple of minutes. 2-3 on the armrests under the plugs, 4 on the mounting of the swing mechanism and 4 on the fastening of the back of the chair to the seat, the number of bolts depends on the design of the chair.

Next on the list are swing mechanisms, which can also creak in the absence of lubrication, and the lubrication is far from durable and often dries out in the manufacturer’s warehouses. Let's look at the most common mechanisms: multiblock, knee mechanism and top gun. It’s not worth getting into the multiblock on your own; we don’t even remember a time when it creaked at all.

The most common squeak in a chair is the gas lift squeak. When you sit down in a chair and hear a crunching or squeaking sound from somewhere below, but don’t understand exactly where the sound is coming from, the 100% reason is the gas lift itself. You can take it apart and lubricate it yourself without difficulty or fear. We will clearly demonstrate how to do this.

Turn the chair upside down. Directly in the crosspiece on the back side of the gas lift column, using a flat screwdriver, you need to remove the latch holding the gas lift rod and the washer. The stories about how a gas lift will fly up like a rocket are never justified. A gas valve on a working gas lift will not break during such disassembly, unless you try to weld its rod to the swing mechanism or under blows from a sledgehammer.

Then carefully and evenly lift the cross up, the gas lift column will remain on the cross and all the internal elements of the gas lift will appear in front of you. Next, we simply lubricate everything in front of our eyes: the bearing, support washers, rubber gasket, the very top washer, which is adjacent to the column inside, most often because of its dryness, a metal creaking appears.

You can disassemble and lubricate each element separately, just be sure to remember the sequence: a rubber gasket is placed on the piston rod, then a support washer, a bearing and another washer follow. The piston rod itself can be separately lubricated with low-viscosity oil - this will give the gas lift a couple of extra HP to its life expectancy;)

After lubrication, we put the gas lift column on top and secure the rod with a washer and a latch. Don’t be alarmed if you see a plastic washer instead of a bearing or one metal support washer is missing altogether. Due to the wide variety of gas lifts, their design may well differ.

As for operation - NEVER swing in a chair with the swing mechanism fixed, thereby you yourself break the gas lift and render it unusable in a matter of days. In any case, if you want to deal with the annoying squeak yourself, then our article will help you.

How to repair a broken leg

Repairing broken legs is a common furniture problem. If the element breaks exactly according to the texture, and when combined, all the parts fit perfectly, then it is necessary to apply wood glue to the ends and compress it well using clamps.

How to fix the leg of a wooden chair if it was originally attached with glue, but is now loose? To do this you need:

• remove the leg from the hole;
• remove remnants of old glue;
• apply a new layer of glue to the base of the leg;
• install the part into the hole;
• secure with a weight, placing it on the seat. Excess glue is removed.

It is recommended to use PVA-based glue for repairing the legs of wooden chairs. It must be water- and light-resistant, and also have high adhesive strength.
