The ergonomic polystyrene microbeads allow this cylindrical cushion to offer a wide range of possible uses. When positioned in lateral decubitus, it clamps the patient around the abdomen, thereby preventing them from rolling onto their sides and trapping themselves against the bed's barriers. It can be used between the legs, under the knees or ankles to prevent friction. In a dorsal decubitus position, placed under the bent knees, it acts as a fairly firm support to prevent possible contrary curvature of the joint and tenderness of the area. Positioned under the ankles, it is perfect for relieving pressure on the heels. Surface cleaning.
