An office chair or computer chair on wheels is a convenient and effective replacement for regular furniture. The soft seat and back reduce the load on the spine, and the rollers eliminate the need to get up to take a step to the next table with a shared telephone. Save on inviting an assembler - learn with us how to assemble a computer chair yourself.

What is needed to assemble an office chair
Open the box and place the contents on the assembly table. Read the instructions carefully. Check the completeness of all parts, materials and tools. Everything you need should already be there. The manufacturer includes a special key for fasteners for such chairs that have a head with an internal hexagonal hole.
A modern office chair consists of two main parts - an adjustable seat with a backrest and a support part with adjustable height on roller wheels.
Seat with backrest
It can be made as a monoblock solution, to which armrests can be attached. But usually the backrest is separate. In this case, the set consists of the following:
- back;
- mechanism for adjusting and connecting the seat to the back;
- seat;
- armrests.
Support mechanism
Keeps the structure in a vertical position and allows you to move without getting up:
- gas lift – performs a supporting function, has a variable length;
- star-shaped crosspiece with overlays;
- roller wheels.
Step-by-step instructions for assembling the chair
The assembly will be quick and enjoyable if you follow the sequence we suggest.
Install the rollers into the sockets
First install the rollers into the crosspiece - to do this, insert them with their rods into the holes on the lower surface of the crosspiece and press with force until they click. You can use a rubber mallet, but it is not recommended to hit the plastic parts of the parts hard.
Prepare the seat
Attach the backrest adjustment mechanism to the back of the seat and the piastra to the bottom.
IMPORTANT! When installing, make sure that each screw is equipped with two types of washers - a flat one (it increases the contact area of the inner surface of the head) and a locking one - to prevent the nut from unscrewing.
Manufacturers offer various options for adjusting the position of the back and seat to the particularities of the spine of the person sitting. The most common are:
- piastra - can only regulate the vertical displacement of the seat and back relative to the floor, used in conjunction with the PVM;
Office chair piastre mechanism - PVM (spring-screw mechanism) – reliable and unpretentious, regulates only the angle of inclination and the distance of the back relative to the seat, used together with the piastra in inexpensive models;
Spring-screw mechanism for rocking the chair - Top-gun – provides “swinging” of the monolithic seat at an angle from 95 to 130º, but in this case the legs can come off the floor and the chair can tip over. When choosing such a product, give preference to a mechanism on bearings with a tilt axis shifted to the edge and a working position lock;
Top Gun Office Chair Rocking Mechanism - synchronizing mechanism - under the influence of the gravity of a person's weight, it automatically changes the angle of the seat simultaneously with the change in the position of the seat, the most expensive solution for top managers.
Synchronizing mechanism for an expensive office chair
When installing, note that the gas lift rod socket should be facing forward, and the nearby adjusting screw with a plastic handle should be facing backward. Insert the armrest brackets into the side sockets and tighten the screws.
Put on the backrest and tighten it with the adjusting screw.
Install the gas lift into the crosspiece
Remove the protective caps from the ends of the gas lift and insert its base into the upper central hole of the crosspiece. Assemble the casing - it is often made of several parts connected according to the principle of a telescopic tube and put it on the gas lift. Insert it into the central hole of the crosspiece. You have assembled the load-bearing part.
Connect both parts of the chair
Place the seat on the gas lift rod and press firmly or sit on it - this is necessary to ensure a secure fit.
Conduct quality control of the assembly
While sitting on the chair, press down on the piastra lever. The seat will go down. Pull the lever up. If it returns to its original position, the assembly was successful.
So, you built a new office chair without your boss's help, and now you can't give it to anyone.
