The cotton twill covered Foam Leg Raiser has been ergonomically-designed to support the back of the knee and heel, whilst allowing the calf to relax. This takes pressure from the lower back and stimulates circulation. Back pain can be relieved and symptoms of swollen legs, varicose veins, oedema and fatigue can be greatly eased; it is ideal for use in a bed or flat surface. Constructed from a high density polyurethane foam with a generous 2 cm deep memory foam topper, the Foam Leg Raiser features a removable, washable cover. Weight of the product is 0.9kg. Overall size is 62cmx41.5cmx17cm.
