Memory foam mattress has been my best friend for the past 6 half years.

I live in the UK & we did the same thing brought a special bed & mattress & we hate it, I can hardly turn over in it or get in & out of bed!! and we haven't finished paying for it yet ( we have had it 18 months now ! ) We regret it also.

I bought a "Sleep Innovations" 2 inch Memory Foam Topper and am very happy with it. Couldn't afford a new mattress at the time and this topper made my bed a lot more comfortable. Since you can't return your mattress I thought this might help you. I also purchased a "Sleep Innovations" Contour Memory Foam Pillow and it is great....Each one of us is different but thought I'd pass this along. Good Luck! Linda
