Obusforme Seat Taupe Support 1 PCWhile Seated, the sitting bones support 75% of the body's weight. The ObusForme Contoured Seat Cushion effectively supports this weight and prevents the sitting bones from sinking into soft chairs and car seats. This places the pelvis and hips in a comfortably balanced position, evenly distributing body weight and reducing spinal strain. The Velcro Tabs allow you to attach this seat cushion to any ObusForme Back Rest on the market.
