This McKesson Contoured Seat Cushion, in a sleek black nylon cover, measures 16 W x 16 L x 3 D inches and is designed for optimal comfort and support, particularly for wheelchair users. Crafted from a combination of foam and gel, this non-inflatable cushion offers superior pressure redistribution to aid in the prevention, treatment, and management of pressure sores. The low-shear, stretch nylon cover is breathable, fluid-resistant, and durable, ensuring lasting comfort. Its waterproof material and unzippable design allow for easy cleaning, making it a low-maintenance option that accommodates spills, perspiration, and incontinence. The open-cell visco memory foam enhances breathability, while the gel acts as a cooling agent to regulate temperature and mitigate perspiration. Specialized features include trochanter cutouts for improved pressure redistribution and pelvic support, molded leg troughs for thigh alignment and postural symmetry, and a raised front ridge to promote proper positioning and prevent sliding. The cushion is engineered to absorb shock and provide pressure relief for users weighing up to 275 lbs. Adjustable straps with buckles ensure a secure and safe fit. This reusable cushion is sold in a count of four.
