The pricing policy for office furniture is directly related to external qualities and technical components.
Whether you use simple fabric or expensive leather upholstery will significantly affect the cost of the chair, but the mechanisms are also of great importance.
If you are faced with the question of choosing a chair for your office or home office, carefully study the technical characteristics of a particular mechanism, depending also on how long you will be sitting in this chair every day.

Types of mechanisms for chairs
The mechanisms, despite belonging to a particular manufacturing company, have similar functionality.
- The simplest ones, used in inexpensive models armchairs, are "piastra" and spring-screw.
"Piastra" is a mechanism for adjusting the chair only in height. The spring-screw mechanism constantly supports the back. The piastra is designed to operate only in the “up-down” mode and is adjusted by pressing the handle.
This mechanism is installed mainly on cheap models of chairs. This is a block equipped with a gas lift control lever, which is used to raise/lower the chair. The spring-screw mechanism is able to constantly support the back with the help of a spring located under a plastic cap.
The spring contracts by twisting and thus gives a hard or light tilt to the back of the chair, which allows the person to relax their back. - Armchair- the rocking chair is the prototype of most options armchairs directors.
The executive chair category is the most popular when choosing office chairs. The swing occurs within 90-130 degrees, mechanism is called centered, or top gun.
In a typical Top Gun mechanism, the chair can be either in the working position (with a straight back) or with the rocking mechanism “on”. If armchair leaning back completely, legs may hang above the floor.
This is possible due to the fact that the tilt axis is located in the middle of the structure and the upper edge rises when tilting. More expensive products allow for some marginal offset of the axis.
This allows the legs to not rise as much. The type of mechanics involves a change in the form of fixing the chair in a vertical position.
Leaning back on the chair allows you to let your back relax. - More complex chair rocking mechanism – multi top gun.
This mechanism also provides for fixing the backrest in the required position. The action occurs by pressing the lever underneath seat.
This feature allows you to provide good support for your back and lumbar region. The large screw at the bottom of the chair allows you to adjust the spring stiffness to suit the weight of the person sitting with the rocking mechanism active. - Expensive office models armchairs are equipped with multiblocks - synchronous and expensive mechanisms, with improved ergonomics.
The multiblock is a rocking mechanism with the highest performance indicators in terms of service life and reliability. Mechanics armchairs allows you to change the angles of inclination seats simultaneously with the same manipulation with back, achieving maximum synchronicity.
It has the most modern design in office chairs, but it is the heaviest and tallest of the four rocking mechanisms. The process depends on the weight of the person sitting in this piece of furniture and allows for maintaining the optimal proportion to ensure unloading of the spine.
The multiblock allows you to fix the position of the chair step by step at five points of different chair tilt angles. Work in something like this armchair gives the owner maximum pleasure, and the back will not bother after being in it for a long time.
Operating it requires significantly more effort to the mechanism handles than, for example, in the MTG mechanism. - Synchro-mechanism, or synchronous mechanism, is a modern adjustment mechanism that provides simultaneous forward-backward tilt of the backrest and seat at the correct angle with fixation (up to 5 positions) and “anti-shock effect”, as well as the option of backrest tilt force depending on weight.
The synchromesh mechanism is capable of adjusting the depth of the seat and can change the position of the armrest in height and tilt. Thanks to its presence, changes can occur provisions headrests and lumbar support cushions.
“Synchronized mechanisms” are the crown of creation, the most expensive and are installed mainly on ergonomic chairs. The model will not allow accidental tipping over, mechanism will allow the body to take the most comfortable position for it.
All this provides relief for the spine and it is much more comfortable to sit in chairs with such a mechanism. The price range of the product goes up depending on the availability of the above and other parameters.
Choosing a chair
Planning to purchase armchair for the workplace, you should carefully study mechanism swinging.
This functionality was invented to create maximum comfort for a person who spends a long time in a sedentary position. position.
In order to avoid negative consequences such as circulatory problems, spinal problems and others, you need to pay attention to how armchair can take on the individual characteristics of a person's body, providing him with comfort.
Mechanisms swings should be aimed at ergonomics provisions human body.
