The Leitz Ergo Active Sitting Stool features a unique Dual Density Foam (DDF) comfort seat with firm ergonomic support core. Similar to a saddle stool, the triangular shape distributes weight evenly across the pelvis and is surrounded by soft foam cushioning to reduce pressure on the thighs and legs. The 9 cm thick seat is designed for comfort and can be used to fully sit or lean which encourages users to sit more upright, providing an ultra comfortable seating experience similar to a seat cushion. Developed together with the Institute for Health and Ergonomics (IGR), this adjustable height ergonomic desk stool has been designed to keep you active while sitting at your desk at home or at work. The rounded wobble base of the stool chair encourages active movement by swivelling and rocking while you work which strengthens your back and core preventing aches and pains. Smooth and easy 17 cm height adjustment range (47 - 64 cm) by pressing the button underneath the seat to switch to the perfect sitting height. The seat cover is made from 100% recycled material and the non-slip rubber base will keep the stool from slipping while protecting your floors. The lightweight design and carry handle beneath the seat makes it easy to move from room to room and it can be easily stored under a desk. This modern and minimalist sitting stool is ideal for your home or office to enhance comfort and maximise productivity. It's our mission to provide solutions that can empower individuals to thrive at work and beyond promoting positive mental health and physical wellness.
