Help me choose a new mattress? I can't decide which one to buy infact I know nothing about matresses but we need a new one. I have terrible back ache when I get up, hips are sore and even my legs are sore. I'm sure it's my mattress. It's quite old and and very springy if that makes sense. Me and my DH are not small people and It feels like we fall into in the middle and it's just so uncomfortable. But I don't know what kind and type to buy. I'm conscious of spending loads of money and then still being in pain and uncomfortable! I only have a budget of about £300 so I'm really struggling especially when I don't know what to look for. The budget can be stretched slightly also I need it now. I ant wait six weeks for it to arrive. I'm losing sleep because it's so terrible.
