Pick your good office chair to see "Four Degrees"

The correct sitting position is of course important, but in addition to habits and persistence, it is necessary to keep it with a suitable seat. So, how to choose a healthy office chair? Please refer to the following four basic essentials.

The height of the chair surface is slightly lower than that of the calf length. The height of the chair surface is mainly determined by the height of the knee nest. If the chair surface is too low, the pelvis will be tilted back. The load of the waist muscles will be greatly increased, and symptoms such as back pain and back pain occur; too high the chair surface will cause the stress to focus on the bottom of the thigh Essence

The chair surface keeps horizontally in the horizontal chair level. If the angle of the chair is not horizontal, the three right angles required by the waist end cannot be maintained, which is easy to form an error sitting position.

The left and right width of the chair surface is slightly greater than the size of the hip size. If the surface of the chair is too narrow, it cannot effectively support the hips, causing uneven hips to cause muscle fatigue.

The depth of the front and back of the chair surface is slightly smaller than that of the thigh length. The depth of the chair surface is too large. When the back is back, the front end of the chair is easily compressed at the knee nest, or the back of the chair cannot effectively support the back, which causes the wrong sitting position.

If you still want to be more comfortable in the office chair, you can also adjust from the following aspects.

1. The chair surface can be padded with a thin and hard pad, neither soft nor too hard;

2. The handrails on both sides of the seat are moderate, and the forearm should be supported naturally to ensure that the forearm and the office keyboard should be parallel to support the armrest when adjusting the sitting position;

3. The rolling wheel of the seat needs to be locked to maintain the stability of the body;

4. The back of the chair is compatible with the physiological curvature of the human body. When the back angle of the chair is 90 degrees, it can better help the spine in the upright state.

Finally, I reminded that every 30-45 minutes, you need to get up to move your body and release the load of the spine accumulation.
