The Span America High-Back Shear Reduction Cushion is designed to provide enhanced comfort, pressure relief, and postural support for recliners and other high-backed institutional seating. Its unique segmented fin design helps minimize reclining-induced shear forces, while three strategically oriented support zones reduce shear in multiple directions. The cushion delivers effective pressure redistribution in both upright and reclined positions, and features extra thickness in the lumbar and thigh areas to help maintain proper positioning and reduce the tendency to slide forward in the chair.
