Hello, I was wondering if you could recommend a mattress topper. We have just bought a new mattress and I am utterly disappointed in it. My husband, on the other hand loves it. It is the Highgrove mattress Desire with 1500 pocket springs. I have two issues with it. Firstly, although it is firm when you first get on it, you very quickly sink into it (I realise now that this is to do with the memory foam). I like a firm bed. It was a terrible mistake to get memory foam. Secondly, I am seriously overheating with the memory foam. We have several egyptian cotton sheets but that lovely "coolness" you get from them is completely lost in the heat of the mattress. I am waking up several times in the night far too hot and sweaty. I have been unable to sleep since having this mattress and I am at the end of my tether!

Is there anything you can suggest?
