With the Pending work chairs, GERLACH TECHNIK already has a system in its product range that effectively counteracts back problems by relieving the spine. The Pending Ponso 1 is a new chair that uses recent developments to do an even better job of protecting your back. The Ponso seat principle optimizes the sitting position, relieving the spine and vertebral disks. The pendulum principle ensures that you easily stay mobile, stimulating the muscles. It avoids an unnatural, rigid sitting position. Even pressure distribution from the back to the thighs relieves back problems and encourages relaxed, healthy work. This also stimulates the cardiovascular system, reduces the risk of vertebral disk prolapse, and reduces the risk of shifting the spine. Height adjustment by means of gas lift system. Firmly upholstered back rest. Safety rotating stand with braked castors. Seat width: 46 cm Seat height: min. 46 cm, max. 58 cm Seat depth: 38 cm Height of backrest over seat surface: 21 - 29 cm Backrest width: 42 cm TUNDRA cover material.
