Infinitely adjustable lumbar support
Interstuhl was a pioneer in allowing an exact adjustment of the lumbar support to the individual physique and thus optimum support for the body in the lumbar area with Interstuhl's Air Pressure Technology. The lumbar support is correctly adjusted if the back is supported at the transition from the pelvis to the spine. The backrest offers the back support in a relaxed, upright posture without exerting any noticeable pressure on the spine.
