Available for both folding and rigid wheelchairs, Supracor's new Stimulite Tension Adjustable Back features Stimulite honeycomb to circulate air and evaporate moisture while equalizing pressure for exceptional comfort and stability. The "footprint" of the flexible honeycomb cells stimulates blood flow to enhance circulation. Adjustable velcro straps can accommodate for kyphosis or posterior pelvic tilt. Optional lumbar support. Both the honeycomb and removable, breathable cover are machine washable.
