The Liberty Chair - designed for sustained use, preserves your back
Liberty features auto-recline, form-sensing mesh, and a soft, yet supportive seat cushion built to last. Sit back, relax your back muscles and feel the ergonomically shaped mesh panel envelop and support you, both in the lumbar area and the upper spine. We have tested these chairs over many years of highly intense use and found they encourage a healthy posture, good circulation and a dynamic position, avoiding the cramped up position of most office chairs that maintain a single posture leading to back pain, sore neck and stiff hips.
Still, We do recommend to change position (using a sit stand desk, or getting up at least once every 45-50 minutes for 5-10 minutes at a time, in order to encourage blood flow, stretch your legs and allow your muscles to return to a more natural state.
