My son has been sleeping on this mattress for a while now (it took a couple of years to write this review). He needed a thin mattress for his loft bed and he wanted memory foam and this fit the need list. It's incredibly comfortable and doesn't feel thin at all. My son has trouble sleeping anywhere else. He has a memory foam bed at his father's house and he finds this one to be more comfy.
Been a overstock buyer for over 9 years, purchased the item through overstock.com and it would never reach the 6inch thickness. Customer service refused to resolve the issue after so many emails and photographs provided, they said the picture showed up 6" where as from my view its only 4.5". I suggest not to buy mattress online unless u can pack and return them. These mattress can never be returned after opening.
I bought this two years ago for my daughter' bed, I find myself sleeping in it when she is not home for the night because it is so comfortable. We are buying a second one to stack the two of them for her new daybed. that way when she has sleepovers we can pull it out and make a giant bed for them!
Really great quality for this price... obviously it's not made of angel wings, but I've slept on it a handful of nights in a row and never had any issues. I'd def recommend this as an extra bed, mattress for a lightweight kid, or a daybed.
