Types of computer chairs:
* Chairs for the head. The main thing in this furniture is comfort and status. In addition to the ergonomic shape of the seat and back, it should "speak" about the importance of its owner. Leather upholstery, chrome-plated armrests and a crosspiece have a very impressive appearance.
* A simple office chair does not have a height adjustment mechanism and armrests. This is a budget option with a laconic design.

A chair for long-term work at the computer should be, first of all, with a horizontal back, at the bottom there is a slight bend for the lower back and a depression so as not to slip.
It is better to choose a chair yourself, you need to sit down so that it is comfortable, not too deep, it is desirable that there is support on the sides, because, as a rule, people spend a long time at the computer.
