A really great mattress from an amazing company, I ended up returning it due to various factors, it was kind of light weight and it kept slipping off my bed frame, it would have worked fine if my bed frame had been different, but they made the process easy and user friendly.
Purchased with the hope it would help with my chronic back pain but, since using it for the past five weeks, I can say it has not helped with my pain, but is otherwise comfortable. Customer service was GREAT, in that they sent me a mattress topper at no charge. Sorry to say that didn't help. Will give a little more time before final decision is made.
