Bought this mattress for my elderly husband who has back problem and was assured it would be suitable for his adjustable bed . After a few nights of extreme discomfort as it was too soft I had to swap it with mine . Now I am suffering severe back pain with it so I now have to go out and buy another mattress after only 10 weeks of use . Within that time I was on holiday twice for a week and had no back pain . Not a good buy !
