  • Great quality, great price, but not "soft"

    I ordered this mattress in the soft version for my guest bedroom and although it is fairly comfortable I dont find it to be "soft" at all. It does get a little softer after you lay on it for a few minutes but when you first lay down it feels about like laying on the floor to me. I like my mattresses very soft so it's a disappointment in the firmness but if you dont mind a firmer mattress this is s fantastic price and overall seems to be great quality. It had an odor for all of 5 minutes after unpackaging it and came neatly packaged rolled up like a giant sausage and flattened out immediately. I would recommend ordering the soft if you like medium firmness because like I said I would consider this medium to hard firmness.

    I did a lot of research to find a good memory foam mattress. There was no way I was going to spend $2000 on Tempurpedic, and Overstock had a really good, wide selection of memory foam to choose from. I went with the Comfort Dreams because of the "Select A Firmness" option - I really wanted to make sure the bed would not be too soft. I selected the 9 inch based on online research about other brands, and selected the firmest option available. I compared the description with the description of other memory foam mattresses - I even quizzed a guy at Sleepy's to make sure I was getting something comparable! I am really delighted with the mattress. I've had it for more than a year now, and its firmness has not changed at all. It's super comfortable, and friends who have tried it have all commented on how nice my bed is. I say it's like sleeping on a marshmallow. If you're looking for something rock hard, this is not your mattress. This mattress is not as responsive as a Tempurpedic - you're not going to see the very isolated hand print they advertise - but having tried a Tempurpedic, I can say that the difference is irrelevant. The mattress is supportive, has no hot/cold issues, and definitely inspires a restful night's sleep! Overstock delivered the mattress in a roll, which is very convenient for maneuvering a mattress in a tiny apartment! I got the mattress around 7PM, unrolled it on a bed frame (NOTE: get a bunkie board to support the mattress, or buy more slats to push together - that's what I did), and left it alone to "rise" for about 5 hours. After that 5 hours, the bed was very ready to be slept on. There was no offensive odor after the initial unpacking, but I was careful to have good airflow while I was unpacking and letting it rise. The only minor downside is that the corners are easily squashed when sitting to put on shoes or something, but I put on shoes every day and I'm never bothered! If I were to buy a new mattress, I would purchase this again. Considering the quality, the price is really unbeatable.

    • How did the color on site compare with the actual product? It's very hard to tell about a mattress from a website, but Overstock did a pretty good job.
    • Please tell us about the quality of the product. The mattress is excellent.
    • How accurate was the on site description of the product? Accurate - again, it's a subjective purchase, but Overstock provided good details.
  • positive review

    The bed arrived super fast(we worry about things like that here) and decompressed fully in a couple of hours. The smell was hardly noticeable and not unpleasant by bed time the first night. I do believe the firmness rating should be changed a bit. I ordered a medium, but it's more firm than medium. When I can get a queen I'll be getting a soft. The size variation disclaimer is true, the width is correct, but this full size is 4 inches shorter than the full box frame I put it on. For the price no worries, I'm short too :)

    • How did the color on site compare with the actual product? yes
    • Please tell us about the quality of the product. The quality if fine so far.
    • How accurate was the on site description of the product? Pretty accurate.
  • Disappointed with firmness of the bed.

    The ordering and delivery process was excellent. But unfortunately I am disappointed with the mattress because it definitely is not firm and that's what I ordered. It actually sinks in the middle, the sides are firmer. It's almost as if the mattress had been used and was returned but supposedly you can not return them once opened. Sorry for the negative review because all other purchases through Overstock.com have been excellent.

    • Did the color match the color displayed onsite? n/a
    • How is the quality of the product? Quality good but i ordered a firm mattress and it sinks in the middle.

    It's a great mattress. Just wish it was thicker. But overall it's good.

  • dreamy comfort, but there is a slight odor

    After much research I purchased this Comfort Dreams foam mattress, and comfortwise I am incredibly happy. I am sleeping wonderfully, and some aches I had been waking w on my old mattress have almost disappeared. I would have rated this Excellent but for the issue of smell; I chose this mattress partially bc many people said they didn't notice a smell, and it probably is mild compared to some foam mattresses .. but early on, after allowing it two days to air and fully expand, the off gassing smell was noticeable to me. It is fading, I have had the mattress a couple of weeks now, and expect that it will be unnoticeable someday soon. But I have been changing the sheets and airing it frequently to aid this process .. if I hadn't had to do this, I would have rated it excellent.

  • Crazy comfy and great on my back!

    Great for my back! Don't get firm if you like a soft bed, you will regret it. I have a friend that bought the same mattress, I bought a medium, she bought a firm. I love mine, hers is too firm for her. But the mattress is fantastic!! I've bought one for everyone in our family.

  • Very comfy

    I bought this mattress for my teenage daughter. It is very comfy. She gets a good rest sleeping on it.

  • I'm really enjoying this

    I love this mattress. I got medium and its great. Not too soft, not too firm, Just like Goldylock's bed (smile), just right. I laid it down for the day to allow it to expand and slept on iit that night. My old mattress was a craftmatic and I had it for 12 years. I didn't want to let it go because of the leg and head lifting ability but it simply wasn't comfortable anymore, and you can't keep a bed that kills your back just because it lifts your head and legs (LOL). Ever since I got this bed I haven't looked back and I'm sleeping like a baby. There's nothing like a good sleep...Aaah.
