DIY bar stool repair with gas lift

Recently, you can notice an increase in the popularity of bar stools with gas lift. It won’t be difficult to explain such a trend - a gas lift makes it possible to change the height of a bar stool. Consequently, such a piece of furniture will suit absolutely any visitor (regardless of his anthropometric data - height). However, unlike traditional bar stools, models with gas lift have a weak point. We are talking about the element that changes the height of the seat.

Tall bar stools – high bar stools must be combined with the bar counter itself. In order not to “fly over”, bar owners choose models with adjustable seat heights. Don’t be afraid to choose bar stools with gas lift. Even if the latter fails, you can carry out repairs yourself. Naturally, the gas cartridge cannot be disassembled - it is replaced entirely.

Is it possible to fix a gas lift?

Replacing the gas lift in an office chair is required if the foot does not respond to pressure and the chair is stuck in one position. Of course, it can be repaired, but only a complete replacement is allowed, since repairing certain parts will not bring results.

What is required to independently restore a bar stool with a gas cartridge?

First of all, purchase exactly the same gas lift as the one that failed. As a rule, there are no problems with this. Any furniture store has a whole palette of similar elements.

For disassembly you will need the following tools:

• rubber mallet;
• wrench;
• Screwdriver Set;
• a rubber shield or an ordinary rag.

Using a wrench and a set of screwdrivers, you will need to unscrew the seat itself. It is often separate from the main structure of the chair. If we are talking about plastic analogues, then you will have to remove everything together.

Next, raise the chair to its maximum height. Place your foot on the base of the chair and secure it securely. Using a rubber mallet, apply light blows to the foot of the bar stool, the vector of which will be directed vertically upward.

All it takes is a few well-placed slashes to dislodge the top of the bar stool.

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.

Removing the bottom of a bar stool structure

To completely empty the gas cartridge, lift a bar stool into the air. Keep it suspended by holding onto the gas cartridge itself. Protect the wide base of the bar stool with a rubber shield or an ordinary rag.

Again, deliver several hard blows to the protected part of the base of the chair. It is quite possible that the blows will need to be applied along the entire circumference, gradually releasing the gas cartridge.

Vertical lifting mechanism

There is only one drawback of folding mechanisms - if you are below average height, you will have to, if not jump, then constantly stretch out in order to “hook” the door that is thrown high and close it. Well, European manufacturers of premium-segment fittings have also provided for this: lifting the facade vertically along the body will be more convenient and practical for you.

The modern furniture industry has many types of furniture hinges. These are both four-hinged hinges and ordinary hinges, which were used back in Soviet times. And although modern hinges are an order of magnitude better quality than their predecessors, they are not always suitable for our purposes. Types of furniture hinges that are used today in the production of cabinet furniture:

These loops are universal. They are able to withstand heavy loads and have a significant margin of safety. Four-hinged hinges are available for installing doors with an opening angle from 92° to 165°; hinges can be adjusted in three planes. Such fittings consist of two elements. The first is the hinge itself, which is attached to the door, and the second is the mounting plate, which is attached to the side wall of the product and is subsequently connected to the hinge on the door. In furniture production, four types of four-hinged hinges are actively used, each of which is designed for a specific type of fastening of the door relative to the product itself. The first type of hinge is an overhead hinge; it is used if the door covers the sides of the niche in which it is located. The second type is a semi-overlay hinge, used if two doors fit onto the same side of the product.

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.

PS Be careful, the gas cartridge itself (this is usually a shiny rod) contains gas under high pressure! Damage to it should be avoided. It is not recommended to open it!

It's called a punch. But in the video they used a hex socket head, it seems, 32 mm

Hello, Nikolay. It is 100 percent likely that the gas cartridge on the chair has failed. This problem can be solved by purchasing a new gas lift and replacing it.

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.

To connect all parts, fastening screws with sufficient strength are used.

The difference between gas lifts for chairs and other furniture shock absorbers

Gas lifts for office chairs differ from similar furniture ones in that they have the ability to adjust the position of the seat. Using a pneumatic chuck, you can raise and lower the chair. They also work as a shock absorber, reducing the load on the spine. For swivel chairs, a gas lift is used, where the piston and rod are connected using a bearing. Therefore, the rod rotates easily around its axis. Gas lifts for drawer doors operate in one plane and do not require a bearing in the piston. They also differ in terms of compression strength per kilogram of weight. For example, in a gas lift of a drawer door, its weight and width are taken into account, and in a chair, the weight of a person is taken as a basis.

How to assemble a bar stool video

Chairs with gas lift are an incredibly practical and functional purchase.
The adjustable height makes them comfortable for anyone. Children, teenagers, adults of different heights - everyone will be able to find the ideal position in relation to the bar counter. In addition, the modern market offers a huge number of seat decor options. Various colors, textures, and materials make these chairs universal and help you choose the right model for any interior. But no matter how hard the manufacturers try, frequent use will sooner or later cause a breakdown of the main part - the gas lift. But even here you can find more of a plus than a minus. After all, such repairs will not be difficult to do with your own hands. And you can always buy a replacement for a broken mechanism in our store.

Assembling and disassembling a bar stool

Note that the gas in the gas cartridge is under very high pressure. Therefore, when disassembling the chair, do not open it. You also need to avoid damaging it. In addition to gas lift, bar stools have a base, a decorative ring, a footrest, and a seat. To assemble the chair, you first need to place the base on a flat surface, put a decorative ring on the gas lift and fix it in the base. Then the footrest and seat are put on the gas lift. Everything needs to be well recorded. Check if the gas lift is working. To do this, you need to press the lever (photo 4).

After assembly, adjust the chair. The bar stool is disassembled in the same sequence. First, use a tool to remove the seat. Then remove the footrest (you can use a hammer). Next, the decorative ring and base are removed. A hammer is also used to remove the round base (it must be carefully knocked out of the tube). Just don't hit it too hard. After this, the gas lift remains in your hands. Remember that such chairs cannot be used as a ladder or stand. Also, the bar stool needs to be carefully looked after (photo 5).

Repair of rickety furniture

If the chair begins to wobble a lot, the problem may be under the seat frame or in the leg area. Let's look at detailed instructions on how to fix a loose wooden chair with your own hands:

1. We change the upholstery. We remove the old layer and change the foam.
2. We inspect the surface for minor damage and repair it.
3. We lay the new upholstery on the seat and nail it to the wood with nails or a construction stapler.
4. If the legs become loose, renew the glue in the holes.
5. If one seam of wooden furniture with a drawer has come apart, you need to make a hole at the bottom or back and pour glue into the damaged area.
6. If the trunnion is damaged, it can be repaired using pegs or a bandage made from strips of paper.
