I bought the 'bed-chair' for my elderly father-in-law. He unfortunately spends a lot of time in bed or sitting on the sofa (he is dependent on care so cannot always choose what time he gets up or goes to bed!). At the moment I would score it 5/5 as he is using it without problems. It has proved most useful while he is in sat on the 3 seater sofa. It helps to support him and stops him slipping off his special pressure-relieving cushion. It also means they don't have to change furniture just yet.
