If the table height cannot be adjusted, only the chair can be adjusted , You can only adjust the height of the chair to fit the table , This may not take into account the comfort of the legs

• The chair is too high ： The foot board is suspended , The feet are not supported by the floor , It's hard to be lifted by a chair （ One solution is to put a box of appropriate height on the ground , Step on it ）
• The chair is too low ： Can't straighten out , The thighs will be propped up , It's very uncomfortable to have your feet askew

2、 It's better to be empty under the table , Otherwise, it will block the foot extension （ Do not put sundries ）

• Elbows are usually placed on the armrest of the chair , Adjust the chair handle to a reasonable height , Put your wrist on the keyboard on the desktop
• Generally, the height of the hand support can let the hand hang down naturally , Instead of being pulled up ; The height of the chair handle and the height of the chair are naturally excessive
