The ability
to change the backrest tilt back and forth. Allows users to adjust the chair depending on how they prefer to sit: straight or slightly leaning back.
The material from which the chair seat is made directly. Note that individual models can be produced in several versions, differing in the material of the seat.
— Textile.
The fabric can have many varieties, and specific characteristics depend on the price category of the chair. And this material is found in all categories — from low-cost models to rather expensive products. The common properties of all types of fabric are low cost, durability, as well as undemanding maintenance.
— Skin. The main distinguishing features of genuine leather are the rich appearance and the corresponding cost. Thus, this material is considered "image" and is used not only for comfort, but also to emphasize the status of the owner. Accordingly, most chairs with
leather seats are designed for executives (see "Appointment") and are in the premium class. On the practical side, the leather is durable, quite pleasant to the touch, but poorly breathable (which can create discomfort in hot weather).
— Leatherette. A variety of artificial materials that mimics the natural leather described above. The quality and properties of a particular leatherette, usually, directly depend on its cost (and the price category of the chair in general), but even the most expensive options are usually cheaper than leather — despite the fact that outwardly and even in sensations they can be almost indistinguishable from i
...t. In addition, this material is not so demanding to care for. Thanks to this , leatherette seats are quite common. Their main disadvantages are the tendency to scuffs and, in general, a shorter service life than leather ones (but again, a lot depends on the price).
— Plastic. Plastic seats are typical of the most inexpensive chairs designed for visitors — or for staff who do not have to sit in one place for a long time. This material is characterized by low cost combined with strength, reliability and an abundance of colours. At the same time, it has one key drawback, which actually nullifies all the described advantages — hardness; Simply put, sitting on plastic is uncomfortable. Because of this, even among the models mentioned, all-plastic seats are very rare.
— Wood. The word "wood" in the case of seating for office chairs usually refers to plywood. This material is in many ways similar to the plastic described above, but it also has some differences: on the one hand, it has an aesthetic appearance with original patterns and is considered more pleasant to the touch, on the other hand, it costs more and provides relatively few design options. However, such a disadvantage as hardness is also characteristic of this material, which is why it is also used only in isolated cases.
— Net. Seats in the form of a rigid frame, in which a fabric or synthetic mesh is stretched. The main advantages of such designs are light weight and good breathability. The design of the nets allows them to be used even in executive chairs. Of the noticeable shortcomings of mesh seats, one can only single out a slightly lower reliability and greater complexity of repair than those of largely similar fabric seats (see above).The material from which the base of the chair is made (see "Base construction").
—
Plastic. Plastic is notable for its low cost, combined with ease of processing — it can be easily given even a rather complex shape. This material is considered less durable than metal, but modern plastics are able to provide sufficient strength even for chairs designed for high loads (see "Maximum user weight"). However this is true only for bases of the "cross" type; for the legs and skids, the plastic is still not strong enough. However, it is found in models of all price categories.
—
Metal. The main advantage of the metal is its high strength, due to which it can be used for all types of bases. At the same time, it is somewhat more expensive than plastic, and therefore, among armchairs with a cross, it is found mainly in models of the middle and higher levels.
—
Tree. Wood can be attributed to design materials: it is used not so much for practical reasons as to provide the chair with a stylish and aesthetic appearance. At the same time, it is considered more reliable than plastic (although not as reliable as metal), so it can even be used for skids. However chairs with wooden bases are quite expensive.
