Nice comfy bed. Not as firm as we expected and it’s not cured my back problems ,but much improved compared to our previous mattress which we purchased from another company who advertises on TV and had previously replaced their first mattress , then supplied us with a second one which was just as bad as the first. We found MattressOnlinewas were helpful when we rang them and we actually got to speak to a real person!

Support around the edges. Firm but not hard. Lovely material and not too heavy to move. Especially like the fact it does not have to be completely turned over, only needs twisting.
