The SoftSpot Lumbar Roll Backrest, model 7150BL, is a back support cushion designed for use to improve comfort and posture for individuals who sit in a chair for long periods.

A center channel prevents pressure points on the spine. The contoured Therasoft material retains its shape to maximize support. The surface is non-abrasive, anti-static, and washable. An elastic strap adjusts to fit any chair. DIMENSIONS (HxDxW): 8 x 2.5 x 14 inches. WEIGHT: 2 pounds. COLOR: Black.
