    • Great Mattress!!

      We have had this mattress for about a month and if I could give it more than 5 stars, I would. The previous mattress was a Sterns and Foster Blisswood but my husband and I think that this is better. When shopping for the S&F, we laid on a name brand memory foam bed and didn't care for it. We both think that this one is far more comfortable. The S&F was a very good mattress, of course, but still my hips and back hurt if I was in it too long. I sleep on my side and it seemed like my hips would hurt where they pressed into the mattress, like a pressure point. Also, for some reason it was hot to sleep in that bed. I know that some people have concerns about heat with memory foam, but this bed is not hot. I was really worried about that because I am warm at night as it is but I have not noticed any problems with extra warmth. I am from Louisiana and purchased the bed in early September, which is still summer down here. The high humidity can be felt inside even with air conditioning, so a hot bed would be pretty noticeable. But no problem with that. We let the bed air out for three days and neither of us can detect any odor. It seems to take a couple of days to really, fully expand. It comes flattened in an airtight wrapping and rolled up in a huge box. When we cut the wrapping off, it immediately started to expand. Later that night we thought it seemed smaller than it was supposed to be, so we measured it. It was a little smaller, but reached its proper measurements by the end of the next day. I think that as the material of the cover stretches a little, the foam of the mattress expands a little more. By the way, I ordered it on a Tuesday night and had it by Friday-very fast! I don't feel the pressure points in hips with this mattress. My back feels better. My husband had a lumbar spine fusion a few years ago and likes this bed better than the S&F. You don't sink down into it very far, but there is less pressure on every part of you. For example, if you sleep on your side like I do, your hips sink a little bit more than your waist, but not too much. Just enough to so that your body is aligned. it doesn't feel like the mattress is pressing back against your hips, though. It's hard to judge firmness because it supports you where you need it, but is just soft enough to be really comfortable. I would say that it is about medium firmness-you don't really sink into it but it gives where you need it to. We wanted a memory foam mattress because my husband is such a restless sleeper. We wanted to see if I would feel less of his movements on this type of bed. I do feel less, but still a very little (this man is a VERY active sleeper!!). But the amount of movement that I feel is greatly lessened. He turns over kind of hard and on the S&F, the entire bed would shake like Richter 5 earthquake was going on. That's kind of hard to sleep through. So now I feel some little movement but not enough to wake me up. He stays in bed more now through the whole night, whereas before he would get up and go sleep on the sofa if he felt that he was keeping me up. If he moved around a little easier I probably wouldn't feel much and I am a light sleeper. With the S&F I could feel every movement,even though that's a pretty good bed. We covered it with a Croscill 500 thread count pima cotton mattress pad, also from Overstock, and that has been wonderful also. It has just a little padding, will protect the mattress and is not hot, either. This is a really great mattress for a good price. I would order it again if I had it to do over.

    • Look elsewhere

      After less than 6 months use, the mattress had major sags on both sides, creating a hill in the middle that signigicantly complicated the marital aspects of the bed, not to speak of its overall comfort. The manufacturer was completely UNRESPONSIVE to repeated requests for attention under its 10 year warranty program, Thanks to for making it right.

    • I love this mattress!!

      I have had it for two weeks with no complaints! The mattress arrived as promised and it was easy to mange becuase it is all rolled up in a shipping box. Once I released it form the box it took a day or so to come to full height. I didn't notice a smell that I have read about with other mattresses. My sleep has become so much more restful, and I don't have those pressure point problems with my shoulder and hip. It also controls motion so my husband does not get distrubed when I get up. It is semi firm but not to much. It also gives you a firm support if you are a back sleeper. I would buy another one and recommend it to a friend which I have already done.

    • Product is not as advertised

      We received our mattress in good order. However after letting the mattress fully inflate on our platform bed frame we discovered that this mattress has very little support. After unzipping the cover we discovered that it does not have the 4 inches of memory foam as advertised. And I would bet that the 2 inches of memory foam that it does have is not 4 lb. foam as advertised. This is our second memory foam mattress and we will be getting rid of this one and trying to find one that has better support/firmness.

    • Was the gamble worth it?

      I've been sleeping on this mattress for about a month now. The box came very quickly, I opened it and let it expand and air out for four days. There was some odor to begin with, not bad, but I didn't want to sleep on it until it fumed out. The first night. Very different, sinking into the top layers of foam, and then, hardness. This is not a medium mattress. It is very firm, even hard. After about a week, I decided to get creative. I ordered a 3" memory foam gel topper. I let it air out, put it on, and for the past two weeks I don't want to get out of bed in the mornings. That is a plush but firm bed. Exactly what I wanted in the first place. I don't know how long these foam mattresses last, but for the price, it was worth the gamble. I said I would recommend this to a friend but with recomendations. Would I order it again? Yes, with the topper of course.

    • Does this mattress contain Polyurethane?

      • Not sure, but it did not have a noxious odor.

      • The reflexive base support foam is a high density polyurethane foam

    • What is the country of origin?

    • So do you just set a memory foam mattress on the slats for the bed frame or do you have to have a box spring underneath the mattress?

      • It depends on the type of bed frame you have. If the bed requires a box spring, one must be used. If it does not, then you do not have to.

      • We have a memory foam mattress (not this particular one) and don't use a box spring. However, we do use a thin plywood board under the mattress to make the support very flat and even.

    • What firmness are these mattresses? Soft, Firm, Extra Firm, etc.?

      • Memory foam mattresses have different densities that determine the level of firmenss. This mattress has a top layer of 4 pounds foam, which is firm and a second layer which is 3 pounds, which is softer. You can also view our memory foam buying guide for more information.
