“I have given the mattress a 5 star rating for the moment. I have no idea what the long term use will bring. It is comfortable. I was totally surprised when it arrived in a box. Even more suprised when I took it out of the box and cut the plastic away and it burst into a full queen size mattress! The only concern is that I couldn't find a warranty for the mattress and am contacting the company to find out if there is one.”
