I have been looking for a memory foam mattress for my guest bedroom and didn't want too spend too much on it so this seemed perfect. I have ordered another brand of memory foam from Overstock and absolutely love it but didn't want to spend quite as much (even though that was a great value) since it's only used once or twice a week by my collage aged daughter. I think the size is perfect and it did rise to almost the full 10 inches rather quickly. The only downside is that it is a bit too firm...I love a firmer mattress but this doesn't quite have that memory foam feel to it. I did put a 3 inch memory foam topper along with the memory foam cover that I also purchased from Overstock and that helped a bit. I may still need to get an additional topper for a lttle more comfort. However, my daughter and my mother have both slept on it and while they admit it's a little on the firm side they both said they slept great on it and had no backaches in the morning. I plan on getting this for my other daughter since she loves a firmer bed. I would definitely recommend this to anyone that likes a firmer bed.
