The Leitz Ergo Active standing stool has a unique Dual Density Foam (DDF) comfort seat with a firm ergonomic support core. Similar to a saddle stool, the triangular shape distributes the weight evenly across the pelvis. Thanks to the particularly soft foam padding around the support core, pressure on the thighs and legs is reduced. The 9 cm thick seat is designed for comfort and can be used both as a standing aid for leaning on and for sitting on, which encourages a more upright sitting posture and creates an extremely comfortable sitting experience. Stylish and ergonomic standing stool that keeps you active and supported while standing at your desk, compact design for under-desk storage.
