I was shopping for a new bed and mattress for my 10 year old son. He really wanted a memory foam mattress. Naturally, he asked for the brand he'd seen advertised. I began to search for the best mattress at the best price, and I came across this one, at Overstock, for a great price. The shippng was free, and it was delivered very quickly. Once we unrolled it , it began to expand very quickly. My son was so excited! He couldn't wait to sleep on it. Of course, he conducted all of the tests he'd seen in the commercials, and was pleased that it seemed to perform to his satisfaction. If you've never used memory foam before, it definitely has a different feel than a conventional mattress. He loves it, and claims he is much more refreshed in the morning than he was with his old mattress. I only have two minor complaints: first, there is still a slight lingering chemical smell. If the window and door are both open, it is not noticeable. But, in a closed room, I can still notice the odor. The second is, that one corner of the bed has never completely expanded to the full 10 inches. It sags a bit, and yes, this was the part that was the inside of the "roll". It's not enough to make me return it, though. All in all, I am very pleased with this mattress. I'm glad my son was able to learn that it's wise to shop for quality and price. It's just what he wanted, and at a price which didn't break my budget!
