Suited to a larger user or anyone with a smaller curve in their lower back, this moulded foam back support cushion that is curved both vertically and horizontally to correctly support the spine and lumbar area. Designed for use either sitting or lying, the Mark II model features deeper sides that hug the body and provide added lateral support, compared to the Standard model. It can be used in the car, at home or office or on a wheelchair. The vertical curve helps the spine to maintain the correct ‘S’ shape. The horizontal curve gives firm, gentle support to the back and protects against the body rolling to the left or right. For best results it should be used against a fairly flat, firm surface. The Back Eze comes with a navy blue, stretch fabric cover that is easy to sponge clean. This cushion measures 330 mm high, 350 mm wide and 110 mm deep. designed for larger users suits people with smaller curve in lower back vertical curve maintains ‘S’ shape horizontal curve protects against rolling navy blue stretch fabric cover used sitting or lying
