What is the best quality for the price on a matress?

Question:My fiancé are... rather over weight (working on it and getting there woot!) and it is too hot to sleep together on his full size matress. We want to get a king or possibly a queen sized bed and I was wondering what you all think is the best type of matress.

Answers:
My husband and I looked long and hard at mattresses before we found one by Restonic. My husband sleeps like the Exorcist and I prefer comfort first. We found the perfect mattress for us through a wholesale to the public place and it's AWESOME. Not only did we only pay $700 for it, but it is FAR more comfortable than the Seeley we had before.
