The Topstar SITNESS H, Model H1, is a newly developed standing aid designed for active sitting. It features a blue-patterned triangular polyester seat and a patented segmented sole made of thermoplastic polyurethane (TPU) that adapts to the ground like a high-tech sports shoe. This ensures dynamic movement while maintaining high stability. Suitable for use in offices, workshops, kitchens, and households, it promotes movement at the workplace and prevents back problems. It offers stepless seat height adjustment via a black lacquered gas spring with a release lever under the seat. The frame is made of black plastic and steel, supporting up to 110 kg.
