The Leitz Ergo Active Standing Stool – Light Grey is an ergonomically designed stool that promotes active sitting and healthy posture for use with standing desks or high tables. It features a 9 cm dual-density foam seat with a triangular shape to evenly distribute weight and encourage upright sitting. The stool’s height is easily adjustable from 57 to 82 cm using a pneumatic lift, and its rounded wobble base allows gentle rocking to engage core muscles. A non-slip rubber base protects floors, while the lightweight design with a built-in carry handle makes it easy to move. Supporting up to 110 kg, the stool also includes a seat cover made from 100% recycled, OEKO-TEX certified material and meets TÜV and GS safety standards.
