Beth,

Is it a Memory foam mattress?? I have a memory foam pillow I sleep on ..and that kinda sounds like it. I have to sleep on my sides, I just can't on my back or front. And with my left side hypersensitive/numb and my right side is the side that gives me muscle spasms I don't know what I'm going to do. Maybe I'll just keep experimenting until I can find something. Thank you!!

Monique
