Kneeling chairs (sometimes referred to as posture chairs) encourage "active" sitting. Users feel the instant improvement in posture whilst using a Putnam's kneeling chair. The angled seat tilts the pelvis forward and helps to create the natural "S" shape of the spine. Choose from Standard foam or memory foam and optional coccyx cut out to reduce pressure at the base of the spine. Our chair was recommended in Writers Forum magazine in 2019 as the best chair when sitting for long periods of time.
