The Kölbs Supra Visco is a general use back cushion designed to help improve the comfort of those confined to a wheelchair. At the core of the Kölbs Supra Visco is high quality sculpted foam, contoured to conform to the user’s spinal curvature.
Additionally, the ViscoBack Cushion contains a rigid insert that reduces the "hammock effect" commonly associated with sling-back wheelchairs. The cushion cover is fire retardant and removable for easy cleaning. It is also specially treated to make it moisture proof, yet it remains vapor permeable to help reduce sweating, and increase air flow. Straps on the back of the cushion allow the user to fasten it securely to the seat back.
