Hi There, Wonder if you can help?

I am currently in the market for a decent mattress for my wife and I. To give you a few details that may help point me in the right direction.... I am 6ft 2" and 16 stone with Lower back issues (Work Related), My wife is 5ft 2 and approx 13 stone (Im not going to ask the question and I hope she doesn't see this!) She is also currently 14 weeks pregnant so she needs some decent support as do I!

I also tend to get quite warm & turn over quite a bit at night either through back pain or just fidgeting and don't really want to wake her up or disturb her too much. Both my wife & I prefer a firmer feel mattress than a very soft one. We currently have a 4ft 6" Leather Otterman type base that we would like keep (The room is not big enough to allow a King Size unfortunately!). I have been looking at the so called 'memory foam' mattresses from a well known maker beginning with a 'T' but have read that they can cause quite a bit of heat to build up through the night!

I like the idea of the extra support a foam mattress could afford over a spring jobbie, and have slept on a few 'Memory Foam' beds in hotels and the like and they were very comfy, but obviously living with one long term not just for a night or two is another matter. we have a budget of about £1000 but obviously with a littl'un on the way any money we can save and use else where is a bonus!

Any advice you may be able to give would be great. Many Thanks.....Chris >
