Supra Visco Back Cushion

General use back cushion. Helps improve the comfort of those confined to a wheelchair. At the core is high quality sculpted foam, contoured to conform to the user's spinal curvature. Embedded in the core is a premium memory foam insert in the lumbar region to aid in relief of lower back pain. Contains a rigid insert that reduces the "hammock effect" commonly associated with sling-back wheelchairs. Cover is fire retardant, removable for easy cleaning, specially treated to make it moisture proof, yet it remains vapor permeable to help reduce sweating and increase air flow. Non-slip back and straps allow the user to fasten securely to the seat back and helps insure proper cushion placement. 12 month limited warranty.
