Rocking stiffness level
The ability to change the force required to tilt the chair (or only the backrest, if the seat is fixed).
Swing stiffness adjustment provides adjustment to the weight and preferences of the individual user.
Seat material
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).Back material
The main material used for the back of the chair. Note that some models are available in several design options that differ in materials; for such models, all available options are given.
-
Fabric. Relatively inexpensive and at the same time quite practical material. It has good strength, unpretentious care, while it can be performed in a variety of colours and designs; in addition, it provides good ventilation, which can be useful in the heat.
— Skin.
Genuine leather is expensive and well emphasizes the status of the owner (especially since the leather products themselves look solid and rich). Accordingly, the main area of use of this option is executive chairs (see "Appointment"). On the practical side, the skin is durable, quite pleasant to the touch, but it does not breathe well (which can create discomfort in hot weather) and requires some care, otherwise it may lose its “presentation”.
- Leatherette. There are many varieties of leatherette, which differ markedly in price and properties, and the most advanced of them are used even in premium executive chairs.
Leatherette backs are not as demanding to care as genuine leather, but are less durable and more susceptible to wear and abrasion.
-
Grid. The backs are in the form of a rigid frame, in which a fabric or synthetic mesh is stretched. Th
...e 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, one can single out perhaps a slightly lower reliability and greater complexity of repair than in a fabric similar in many respects (see above).
— Plastic. Pure plastic backs are most often used in chairs with seats made of the same material (see above). They are durable and inexpensive, but due to their rigidity they are rather inconvenient, as a result of which they have not gained distribution even among models for visitors.
- Wood. Wooden backs are in many ways similar to the plastic ones described above, except that they cost a little more and can have an original appearance due to the texture patterns of the tree. They are also rarely used because of the rigidity and the inconvenience associated with it.
