• A height-adjustable working chair with an adjustable seat back should
be used during extended work periods at the cabinet.
• When the forearm rests on the armrest, is should be in a nearly
horizontal position.
• When the upper leg is in a horizontal position, the angle between
upper and lower leg should not exceed 90°.
• To compensate between the floor and sitting height, a footrest should
be used. The minimal effective size of the footrest should be 18 x 14 in
(45 x 35 cm). The slope should be adjustable to within a range from
5° to 15°. The adjustable height should extend to a minimum of 4 in
(11 cm) above the floor.
