The Vicair Liberty cushion consists of a two compartment layout to limit sliding in wheelchairs and is often used in static seating. It features an automatic air valve which allows the cushion to adapt to your body shape and weight. Inside, it is filled with individually wrapped cells in silicon providing comfort with a low to medium level of support and pressure ulcer prevention. The Vicair Liberty welded design also ensures the cushion is easy to clean and disinfect.
