    • Great Product, Great Price!

      I was looking for a high quality memory foam mattress that wouldn't break the bank and found just the one! Letting the mattress take shape only took 30 minutes, but I let it air out for the entire day. Still a little hard, but it will soften more with time! Overall, incredibly pleased with my purchase!

    • Don't buy!

      I bought this for my daughters room. I read the directions before I did anything and it said it could take up to 72 hours before it completely unfolds to its original shape. I am now on day 5 and the mattress is half unfolded and doesn't seem to be changing at all. I now have to go through the hassle and send this junk back. I wish I would of listen to my gut and not order this. Really shocked at all the positive reviews this thing got. Learned my lesson, will never order a mattress online again....

    • Great Purchase

      I purchased this mattress to replace a cheap innerspring mattress purchased for use in an infrequently used guest room. However, I was sleeping on the innerspring mattress more than I could handle, so it had to go. In its place I purchased this Serta 12" Memory Foam Mattress. After searching local mattress shops who want to screw you over with overpriced mattresses of questionable quality, I searched Overstock and found this mattress. Fits my needs perfectly. Thick and comfortable, I can't wait to crawl into it at the end of my 12 hours at work. The price was reasonable as was the shipping...***. This is a purchase I would make again, and plan on doing just that when I'm able to get a bigger place so I can have a queen bed. This will then go into the guest room. My French Bulldog and I LOVE it.

    • mattress for my teen

      My 13 year old needed a new mattress, and this was kind of a shot in the dark. He wanted a memory foam, but I knew I couldn't afford a big store brand ( you know who I'm talking about). Tried this, had great reviews, and they are right! Great value, he's had it about 2 months and loves it. My husband wants one for us now. It came in just a few days and was very easy to set up, although I did need help to move it in, it was kind of heavy. It came up to full size in a few hours. Buy one! You will not regret it!

      • Hello cbeni83, this mattress does not include a foundation/box spring. It can be used with most platform beds and frames. I'll link you to a great option: - Thanks for shopping with us! L.B.

      • No it does not come with a box spring. We paired it with a platform bed which did not need a box spring. It is a great bed.

      • No. I used my old box spring and is it fine.

    • The reviews for this item are anything from very soft to very firm. Is this meant to be a firm, medium or soft mattress?

      • Firm, but not too firm. I'd say a medium-firm.

      • For a normal weight person it is firm.
