What are the factors that determine the firmness of a chair?

The chair is one of the important tools for people to rest, people love it, whether it is a traditional wooden chair or a modern chair with various styles of materials, the rationality of its structure, the selection of materials, and the quality of hardware are the factors that determine the firmness of the chair.

A good computer chair should be composed of five parts: five-star feet, air pressure pump, chassis, seat and back. Only when each member performs their duties and coordinates can they form a comfortable and durable chair.

The first part is the five-star feet, that is, the five wheels of the sliding computer chair, which bear the weight of the human body and are related to the durability of the chair. The wheels of many cheap computer chairs are made of plastic or even waste plastic, the physical properties of plastic are not good, too soft in summer and too brittle in winter, and people often encounter the situation that the wheels suddenly break when they are used. The better wheels have the right amount of nylon added to the plastic to increase their abrasion resistance.

Of course, stainless steel and aluminum alloy cast wheels are even better. The second part is the pneumatic pump, which is responsible for the lifting of the computer chair. Industry insiders pointed out that the difference between a good air pressure pump and a poor quality air pressure pump is about 7 times.

The steel wall of the poor quality air pressure pump is very thin, and the valve is not tightly sealed, which will leak after a long time, causing the chair to be unable to lift and fall. Lin Lan taught you a way to test the quality of the air pressure pump: raise the chair to the highest, and then lower it little by little, if the chair is lowered to the bottom at once, if there is no rebound feeling when descending, the quality of the air pressure pump is not good enough.

The third part is the sitting board, which should conform to the curves of the human hips and thighs. The density and thickness of the sponge covered on the seat board are related to the comfort of the seat, if the sponge on it is too thin and the density is not enough, it will be "unsafe" for 3 months. The fourth part is the back plate, this part should be in line with the human body function, the tighter the curve with the human spine, the better, the elasticity and toughness of the back plate is an important factor in determining whether it is comfortable.

The fifth part is the chassis, which is the brain of the chair, through which almost all functions are realized. The chassis can manipulate the angle at which the chair reclines or leans forward, as well as how soft or hard it is, and the chassis function determines whether the entire seat can be reclined or only the back panel. <>

The use of space by single chairs is more variable than that of multi-person chairs and sofas with large areas. The single chair also has different functional uses in the use of space because of its different circle back shapes, and if it is used properly, it can reflect the personality of the owner, and it will be self-defeating if it is not appropriate; The high-back single chair is suitable for home use, which can convey a casual and relaxed home atmosphere; The chair with streamlined shape, strong color contrast, and strong visual beauty is very suitable for single aristocrats or studios; Lounge chairs, reclining chairs, and rocking chairs with a strong personal style are suitable for placing in a corner of the space or on the balcony as a transition station for mood. For the newly purchased leather chair, first soak the towel with water, wring it out and wipe off the dust and dirt on the surface of the chair, and then gently wipe the leather surface with a conditioner once or twice (do not use waxy care products), so as to form a protective film on the surface of the leather, so that the dirt in the future is not easy to penetrate into the pores of the dermis, which is convenient for future cleaning.

Primitive people first find a natural chair to use! They don't have a concept of a chair, they just think it's useful. Then after I didn't have that thing, I wanted to make that thing myself, and at this time, I named it a chair!

So from the main **: the concept of the chair is built after the chair.

From the material of the guest **: the first natural chair, then the concept of man.

But after all, the word "chair" is a person's concept of things, and it is also a subjective thing, so there is a concept first and then there is a chair. Both humans and animals are accustomed to using concepts to characterize material entities! This leads to the formation of a substantial consciousness in the brain!

Even without the simple table, the concept of the table still exists in the form of human consciousness and cognition! The creation of a table through the concept of a table does not mean that the concept of the table precedes the entity, but only that the table is created with the cognition and consciousness of the table. And this consciousness and cognition are the concepts that allow human beings to have cognition and consciousness of the table entity!

Entities exist in an objective way before concepts.

Dear, hello, I am glad to answer your question, what are the advantages of different material structures of chairs. Answer: According to the material of the chair, it can be divided into solid wood chairs, steel and wood chairs, panel chairs, glass chairs, plastic chairs, fabric chairs, leather chairs, etc.

The solid wood chair has the characteristics of natural stove wood and is free of chemical pollution, but in addition to its natural beauty. The steel and wood chair is suitable for outdoor use, and its surface has been extended after some special treatment to prevent rust, and it has the characteristics of being strong and reliable, economical and durable. Fabric chairs are made of a variety of different styles of leisure chairs using a variety of fabrics that are not cracked, so that they are suitable for various decoration styles.

Plastic chairs have the characteristics of freedom and creativity, because of the plasticity of their raw materials, so that they can adapt to most interior decoration styles. Hope it helps.
