The OBUS Forme is a back support cushion designed to provide proper spinal support in any chair, auto seat, sofa, or bed. This support conforms to the natural contours of the spine to guide the back into a correct anatomical position, allowing it to relax. This posture eliminates lateral pressure on the spine to reduce fatigue and discomfort and to provide support for the upper rib cavity. The support is available in high- or low-back models and can be fitted with an optional lumbar pad for extra support of the lower back. The device consists of an impact-resistant polycarbonate, biomechanically molded frame covered with three grades of high-resilient urethane foam and an open-weave, non-allergenic brushed nylon fabric. DIMENSIONS: 22 x 17 inches. WEIGHT: 32 ounces. COLOR: Black, brown, burgundy, camel, grey, green, taupe, and two shades of blue. WARRANTY: Unlimited warranty for the lifetime of the original purchaser when the warranty registration is completed and returned.
