If it's a big room, just put a chair on the wall 600mm just according to ergonomics;
Housekeeping in the specific circumstances, if the space is not large, can only rely on the wall,If you can have two channels, place it in the center.
It's 1200mm~1400mm off the wall, and there's an overhead passage just behind;If there is a sideboard between the table and the wall, leave the 1200mm~1400mm between the cabinet and the table so that the chair can be removed and the contents inside the cabinet removed.
