  • Very comfortable!!
    Verified Purchase

    After searching on various sites I read all the reviews here and ordered this foam mattress for my daughter who was expecting her second baby. She is very happy about the comfort level it provides and of course the size is great too. It really is a quality mattress that is sturdy and definitely not overly soft or spongy. It gives good support for her back and took only a couple days to fill out and be ready for use. Had light smell at first which dissipated soon after we set it up. I consider this a great buy and the price point was excellent!

  • Okay, but I wouldn't recommend
    Verified Purchase

    We had a water bed for over 30 years. We thought memory foam was the way to go. As far as firmness, the bed is very similar to a water bed. But the foam does not absorb body heat like a water bed. Thus, we wake up several times a night overheated, throw off the covers, get cold, pull the covers back, and the cycle begins again. We have tried a cooling mattress cover but that has not alleviated the problem. Because we have used this mattress for almost a month, we can't send it back. We will have to get another (probably more expensive) mattress and eat the cost of this one. Trying to find an inexpensive mattress will cost us plenty. You truly do get what you pay for. As far as is concerned, I'm very pleased with their service and delivery. We let the mattress air about 48 hours, and it was fine. The mattress was delivered before the listed date of arrival, in good condition, as expected. The heat issue is the only problem we have. I've been told that's because it's probably Chinese foam, which is more dense and can't deal with body heat like looser foam. It's a shame because everything else is fine.

    I had bought this bed last week, and received it yesterday, Fast delivery about 3 days to get here, We set it up and let it get its foam structure up, They said to wait 72 Hours before actually sleeping on the bed, once we got it set up, it only took a couple hours, We slept on it the same night, It's amazing, Its everything we thought it would be, Its not too firm and not to soft, It is a Medium. Some people had a foam smell on theirs but I never smelt anything like that. Its a quick easy set up. If you are looking for a big bed, then buy this, it does keep you cool. Very happy and please with this bed, It is about 70 LBS. Very very pleased!!!

Questions & Answers

  • Q:

    "Why did you choose this product?"

    • A:

      We bought full size for our kids before and they are very comfortable.

  • Q:

    "What is the fire retardant made out of? are there carcinogenic chemicals in the mattress like there are in almost all mattresses made in the US?"

    • A:

      Hi jackieanderson, we were able to verify with our support team. The mattress identified as Overstock SKU 12375940 contains two layers of polyurethane foam. One is a visco-elastic foam and the other is conventional foam that does contain a fire retardant. The composition of this fire retardant is proprietary, but it does not contain any halogenated materials. To best of our knowledge, there are no carcinogenic materials in either of the foams that comprise this mattress. I hope this help, if you have any other questions please let me know.

  • Q:

    "Approximately what are the dimensions and weight of the 'very tightly packed' shipment? Want to make sure I can get the delivery in the house."

    • A:

      It is about 70 LBS,It's rolled up, so its in a plastic wrap, and cardboard.

  • Q:

    "What type of bedframe and boxsprings are needed for this mattress?"

    • A:

      This foam mattress need something completely flat underneath. It doesn’t matter is customer use box spring or flat bed just make sure is completely flat.

    • A:

      We bought a Platform for this bed, no need to buy any box springs if you get a platform, unless you still want boxsprings
