Wheelchair cushions are designed to provide extra support and protection for regular wheelchair users. The Visco-Tex cushion from Harley is designed for users who find themselves in the High Risk category: namely those who are sat in the same position on a daily basis for significant lengths of time. The lack of movement and subsequent restrictions mean that these people are at an increased risk of developing pressure sores or other complaints associated with periods of immobility. A base of polyurethane foam gives the cushion its grounding in stability and support. The visco elastic memory foam top layer provides the user with comfort and pressure relief by contouring to the user s body to provide continuous and even pressure distribution
