greyowl said "Memory foam as a surface material not great. Very comfortable but HOT. Newer materials available that still provide a top comfort foam mattress without the heat. We were fortunate to get one from Sears before it crashed and wouldn’t trade it for a spring mattress. 14” thick and it can be lifted with one hand. Please check customer reviews online before shopping Sleep Country. Customer service TERRIBLE. Warranty worthless. They do not deal with warranty in store. You have to deal with head office in Ontario. Just read their reviews. Just thought I’d toss that in so you don’t make the mistake we did. "
We bought two mattresses from them. Had awesome service, great deals (always haggle with them), very knowledgeable salesman.
They even deliver on Sunday's which is great.
Sorry, I did not help your question about Memory Foam, but just wanted to we were very happy dealing with them.
