The comfort of a chair is very important, and a good chair should be adjusted freely, by adjusting the backrest, seat surface and armrests to achieve maximum comfort. Otherwise, sitting for a long time will also cause back pain.

Sitting still for a long time will slow down the speed of blood circulation, which can easily lead to various occupational diseases such as constipation, varicose veins of the lower extremities, and hemorrhoids. If your friend or loved one spends long hours at a desk, there's nothing like giving him a comfy chair to express your love. Here are some ways to choose a chair.

1. Armrests

The easiest way for a novice to judge whether a chair is good or bad is to see whether the armrest of the chair is connected to the back of the chair or to the seat cushion. The armrest is connected to the back of the chair. When leaning back, the armrest can be connected to the back of the person. Keep the same angle for comfortable arm support. The armrest of the chair is almost connected to the seat cushion, and when leaning back, the angle of the seat cushion inclination is inconsistent with that of the seat back, that is, the waist of the person. As a result, the arms cannot be placed comfortably when leaning back.

2, lumbar support

When it comes to the comfort of a chair, the most important thing should be the lumbar support. The older you are, the more sensitive you are to this. The lumbar support is not as simple as there is and no difference, because although many chairs will put a large lumbar support, but sitting up does not feel at all. In fact, the lumbar support may be the most technical component of the entire chair. There must be a complex mechanical mechanism connected to the entire chair. Of course, the most real test method is to sit on your own. Regardless of various postures, whether the back of the chair can be complete to wrap the back and hold it. A more advanced chair can adjust the lumbar support back and forth, making it easier to adjust to your comfortable position.

3. Backrest tilt force feedback

Different people have different weights, and the required backrest tilt strength is actually different. However, the tilting force of ordinary chairs is fixed, which makes it difficult for people with light weight to lean down, while people with heavy weight lean to the bottom at once, which not only has no sense of support, but also easily falls over.
