1. Cushion.
The general computer chairs are sponge cushions. The good cost of a good cushion is high, so some merchants make a fuss about the cost of reducing the cost of the sponge, or the strength of the material. A good cushion is generally thicker and has a curved curve that fits down to fit the person's ass. In addition, good cushions have better elasticity. If the seat cushion is thin, it is uncomfortable to sit up. If the seat cushion is thick but not elastic, the merchant may have used poor materials.
2. Sitting feeling.
If the design is reasonable, the chair generally has a comfortable sitting posture, and the seat cushion portion has good acceptance and inclusiveness, and does not feel uncomfortable.
3. Backrest.
The backrest should be reliable. Some chairs have loose backrests and make noise when they are leaning back. Such chairs are easily damaged.
4. Overall structure.
Try to shake left and right, if the overall structure of the chair is unstable, it is easy to damage.
5. Handrails.
Try to put it on the armrest, whether it feels comfortable.
6. Gas rod.
If you buy a swivel chair, try lifting the swivel chair and feel that some of the lifting process is smooth. If you feel dry, the gas bar is not good.
7. Freedom function.
Some chairs have a reclining function, try to open the free function, and feel that you can rest assured that "free".
8. Concealed structure.
Turn the chair over and look at its concealed structure. If the parts are found to be rough or even rusty, they are inferior products.
9. Wheels.
If you are buying a swivel chair, check that the wheels move smoothly, and if dry, it is a poor quality product.
