The multi-component construction of the Equalizer contoured positioning cushion features an ultra-comfortable viscoelastic “memory foam” top, a contoured foundation layer for proper positioning of the legs, and an extra-soft relief zone for high risk bony prominences. Three zones of a proprietary, gel-like soft polymer provide added pressure dispersion under the thighs, greater trochanters, and ischial/tailbone region. Moisture-resistant cover has a rugged nylon bottom with a 2-way stretch fabric top and convenient front carry handle. Built-in sleeve in bottom of cover allows use of molded Sling-Fill base for added stability in fabric sling seats; 2-year warranty.
