How to assemble a computer chair, procedure, quality control

The advantages of modern computer chairs can hardly be overestimated - a convenient design provides anatomically correct support for the back, reduces the load on the spine, eliminates the tension of the neck muscles. The only inconvenience is that any office chair is supplied disassembled, and it is not always possible to resort to the services of a collector. In most cases, it is not necessary to understand how to assemble a computer chair, quite simply and independently. First you need to understand the design principle and functionality of each element, and then study the instructions, which are always supplied with the furniture. The description of the assembly process and useful tips collected in the article will allow you to complete all the manipulations without unnecessary efforts, while saving the family budget.

Design features

A high-quality office chair is a complex structure, in the development of which various experts took part - engineers, doctors, designers. The main elements are as follows:

Back and seat. Provides back support and seat comfort.
Permanent contact. A component that connects the two previous elements and is responsible for changing the position of the back.
Five-beam cross. It is the base on which the whole load falls.
Rollers. Elements at the bottom of the crosspiece, responsible for the ability to easily move the chair without damaging the floor covering.
Gas lift. The shock absorber, which guarantees the elasticity of the structure and allows you to adjust the office chair in height.
Armrests. Significantly increase the sitting comfort, especially if supplemented with soft linings, but this element is variable, not all models are equipped with it.

Combines all types of computer chairs with the ability to adjust the position of the seat and back.

Despite the external similarity of all office chairs, they vary in type and model. The adjusting mechanisms also have their differences, which are given in the table.

Spring Screw, or Freestyle (FDA)	It is characterized by an elastic spring under the seat, reliability and unpretentiousness. Able to change the position of the backrest and the degree of effort when deflecting. It is possible to adjust the distance between the back and the seat. It is used in budget models with piastra.
Piastra	Directions of work - only up and down. Used in conjunction with FDA.
Top gun	The mechanism allows you to swing, like a rocking chair. Provides deflection of monolithic seats in the range of 95-130 °. It guarantees the stability of the chair even at the maximum angle of inclination.
Synchronization mechanism	The device is reliable and very durable, with precise positioning of the chair. The set of functions includes tilt and fixation of the backrest, height adjustment, and adjustment of the landing depth. Under the weight of a person, in automatic mode, changes the angle of the seat. It is considered the most expensive mechanism.

Contents of delivery

A complete set is what an office chair consists of. In this case, these are two components: a support part with height adjustment and roller wheels, as well as a seat with a back. For compact packaging and ease of transportation, they are disassembled into smaller parts. Each delivery set is supplemented with instructions, which should detail how to assemble a computer chair.

Assembly of the chair should begin by checking the availability of all components.

The following items are included in the standard set:

roller bearings or wheels - serve for mobility of the chair;
a cross with overlays - the main supporting part;
a lifting mechanism with a casing - is responsible for the height of the seat;
an adjusting element for connecting the back and seat;
two armrests;
back;
hardware;
Allen key
seat.

If the contents of the package correspond to the list, have no defects, scratches, scuffs, you can get to work, the assembly scheme will help. The procedure will not be difficult if you follow all the instructions exactly.

Assembly instruction

In order for the computer chair to serve for a long time without any breakdowns or extraneous creaks, during the installation process, you need to carry out all the manipulations in stages, as prescribed by the assembly instructions. For independent performance of all work, a minimal set of tools and elementary skills in handling them are enough.

Installing clips in the slots

It is most convenient to start assembling an office chair with mounting wheel casters. Placing them in the nests of the cross is easy:

For convenience, the star-shaped part is best placed on a horizontal surface, for example, on a table or floor, with the holes up.
Then insert the roller rods into the slots and press on each wheel until a characteristic click occurs - in this case, fixing will occur. If the strength of the hands is not enough, you can use a rubber mallet - with this tool it will become easier to complete the task.
When the fastening of all the roller bearings is finished, it remains to put the cross on the floor, and then press on it with the whole body of the body, which will help to check the reliability of the fixation of the wheels. On this assembly of the support part is completed.

To beat with a mallet on plastic wheels you need to be very careful so that they are not accidentally damaged.

Seat preparation

The next step is to install the adjuster on the seat. The piastra is attached to the underside, and the mechanism itself is attached to the rear. They are bolted to the seat with a hex wrench. Fasten the fasteners reliably, taking into account the long-term use of this furniture.

In order for the self-assembly of the office chair to be successful, before starting work, you should check the completeness of the fasteners. All bolts must be provided with flat and lock washers to prevent them from untwisting prematurely.

When installing the armrests, it is important to determine the correct location (left, right), otherwise you can mix up the elements during mounting. Applying armrests to the seats, they are fixed - each with three bolts. The back is fastened with a large adjusting screw. There are models of computer chairs in which the armrests are mounted using brackets on the metal housing of the seat.

Installing a gas lift in the crosspiece

Before mounting the lifting mechanism, the protective caps must be removed from its ends - otherwise they will interfere with the normal operation of the shock absorber. After that, the lower part of the gas lift will need to be combined with the hole located in the center of the cross. As a result, the base with rollers will stand on the floor, and the working mechanism will be in a vertical position.

The telescopic plastic casing is designed for insurance, it protects the seated person from falling in case of failure of the lift. In addition, this element performs a decorative function, masking the shock absorber in a ready-made computer chair. Its body consists of several parts, which are more convenient to assemble by stringing directly on the gas lift from above. When the carrier base is ready for mounting the seat, you can proceed to the final stage.

The crosspiece consists of five beams - such a number of them provides the product with maximum stability, but at the same time also provides good mobility, therefore it is strongly recommended not to stand on it, to use it as a stepladder.

Joining the parts of the chair

It should be extremely careful when securing the assembled seat on a bearing base - brute force can damage the gas lift, completely disable it. The main task of the collector is to gently install this element on the lifting mechanism. The procedure does not require special training or special knowledge:

On the shock absorber rod, carefully insert the piastra, which is rigidly fixed under the seat.
Then push it with effort, and even better - sit down. At this point, reliable adhesion of parts.

Using any other methods to assemble the product is not recommended. After all the above steps, the computer chair will be ready for use, you just have to check the quality of the work done.

Build quality control

Check how efficient the chair is, can be very simple with the help of elementary actions. Serviceability of the lifting mechanism is the first criterion that is mandatory for consideration. When testing, you need to sit in a chair, press the piastra lever - under the influence of a person’s body weight, the seat will lower. When the desired level is reached, the pressure on the lever should be stopped. If you pull it up and get out of the chair, the seat will return to its original position.

Silent and trouble-free operation of the elevator is the second criterion that will indicate a successful assembly. For greater comfort, you can adjust the position of the back and start operation, without doubting the strength of the finished product. Correct adjustment of the computer chair is very important, because the convenience when working at the table affects the activity indicators of employees, and the uncomfortable position of the back causes fatigue of the spine.

There are times when office furniture needs to be dismantled. The user who has personally carried out the assembly process of the structure will easily figure out how to disassemble the chair. At the same time, it is important to remember that after prolonged use of computer chairs, the parts in them can be compressed - it is better to work with the help of a power tool. It may also require the use of physical effort, so the fasteners and the interface between the parts will not be amiss to pre-process with technical oil.

If something went wrong when assembling the computer chair, it is better to use the services of professionals - they will not only quickly and efficiently perform all the work, but also provide a guarantee for them.
