The Leitz Ergo seat cushion is an excellent tool for comfortable and active work. The inflatable seat, certified by IGR, can be used on any chair. By creating micro-movements and forcing the body to maintain balance even during sedentary work, it helps strengthen the back, improve circulation, and reduce pressure on the spine. It relieves discomfort caused by prolonged sitting posture or health issues such as sciatica. The square shape offers better ergonomics compared to standard round cushions, due to the increased seating surface and pleasant correct position on the chair. When placed on a chair, it has a load capacity of up to 150 kg and comes with a pump in packaging without unnecessary plastic.
