The Sit-u-Up, with a structured backrest and the more supportive option, is designed to elevate a person smoothly and steadily in bed either on their back or side. The product has a structured backrest ideal for those who need extra support but do not want to compromise on comfort. It sits on top of the mattress enabling it to be fitted to any bed and causes no disturbance to a second person in a double bed. When fully deflated the user can lie down completely flat, making the Sit-u-Up a simple and cost effective solution to a profiling bed.
