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 offers an extremely comfortable sitting experience similar to that of a seat cushion. Developed in collaboration with the German IGR, the Institute for Health and Ergonomics, this height-adjustable ergonomic office stool has been designed to keep you active at home or at employees sitting at a sit-stand desk, at high meeting tables or at your kitchen table. The rounded base of the stool encourages active movement and dynamic sitting as it rocks and swivels while you work. This strengthens the back and centre of the body and prevents pain. Smooth and easy height adjustment by 25 cm (57 - 82 cm) by pressing the button underneath the seat to set the perfect height. The seat cover is made from 100% recycled material and the non-slip rubber base prevents the stool from slipping and protects your floors at the same time.
