    • 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!

    • Serta Memory foam mattress

      I had an older memory foam mattress that was ok but not firm after a few yrs. My new purchase has provided me with a good firm mattress, more to my liking. And as usual, Overstock's price beat out the competition hands down.

    • Very cozy!

      My old spring mattress had finally past the point of "perfectly squishy" and started giving me back pain. Ordered this mattress after lots of researching, paranoia about buying online etc but glad I bought it! Relatively inexpensive. Packaging was excellent (box was heavy and was more comfortable for 1 very strong person or 2 average people). Let mattress air out for 24 hours before sleeping on it. Didn't notice any odor unless I put my face in it (when I first unwrapped it). VERY cozy. Haven't had any back pain since. Sort of squishy and I thought I'd need a super firm bed but this has worked out great. I sleep on my side and on my back. I just moved so it could be the apartment, not the bed, but I sneeze once or twice when I sleep here. A friend of mine sneezes like mad (but takes 1 allegra every day so allergies are already a problem for that individual). Haven't figured out if it's the bed, but I'm thinking it's more likely the apartment with moving furniture and new furniture etc. But a heads up in case that is somehow a trend in the comments. I'd still recommend people buy the bed :)

    • Comfortable mattress

      I was leery about purchasing a mattress online but after reading reviews, ultimately decided to anyway.. The mattress is for my son's room. It arrived totally rolled up in a package. I suggest before unpacking, take it to the room you're using it in. This foam mattress is very comfortable (not too soft and not too firm). My son loves it and so do I. (FYI, there was a mild odor upon unpacking, as mentioned, but it does go away)

      • 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.

    • 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.
