I need a new mattress also. Fixed income so was out of the question. I bought a 3" memory foam mattress from Costco because I knew I could return it if I didn't like it. Read all the reviews and purchased one. It is white on one side and blue on the other. Anyway, I was waking up every day with a sore back. Have been sleeping on this for the last few weeks and I can't tell you what a great feeling NOT to wake up hurting. It isn't hot and it didn't smell. If I had to buy a regular mattress, I would get a memory foam.
