The Prim anti-decubitus horseshoe-shaped flotation cushion is a complement that provides stability and comfort to the user thanks to its polyurethane foam materials that make up the filling and allow a balance in the dispersion of the pressures exerted, resulting in an anti-decubitus cushion of high functionality and quality in the market. Its horseshoe shape allows it to mould better to the contour and its outer cover is removable and washable. It also has two handles that make it easy to put on and take off. It is resistant to heat and fire and is also non-slip. Recommended for therapeutic use in pain relief, but also for those seeking greater comfort in their daily activities and to avoid possible future injuries or discomfort when sitting.
