    • Perfect fit, comfortable, and worth every dime
Color: Dreamlife Size: Queen Pattern Name: 10"
I bought the mattress as a back up from a ebay order that was never delivered. It was troublesome to justify the hefty price but I was able to make due because it was worth it! Never in several months have I slept so soundly. I tend to sleep in all positions and this offers support for each one. I sleep hot and the cooling wrap has kept me from kicking off the covers through the night. I definitely would recommend! Also, to help with the smell, I spray Febreze. ... show more

    • Surprisingly good quality!
Color: White Size: Queen Pattern Name: 12"
I've never purchased a bed in a box before, and I was worried that it was gonna be somewhat poor quality, but this bed is nice! It's both soft and firm. I sink into it a bit, but there's a point where I am no longer sinking, like the mattress is supporting me. I think this might be due to the thickness of the mattress, though I would need to try the standard thickness mattress to be certain. When I unboxed it, as soon as I had the roll bag at all off, it basically sprung the rest of the way out and began expanding. This can be a bit tricky to deal with, and I would say if you aren't a giant of a man like me, maybe get a friend to help you set it up. I also highly recommend getting a good frame for this. I went for a very robust steel frame, so that might have some effect on the feeling I get from laying on it. I have also only had it for a few months, so I might come back with an update after a while. This is definitely an upgrade from a Walmart futon I was sleeping on. ... show more

    • Actually a good mattress from Amazon? Nope, a great one! Made in USA
Color: White Size: Queen Pattern Name: 12"
Was trapped undecided between this and some offerings at Costco. Honestly I don't make that much so even what would normally be thought of as somewhat inexpensive or affordable for a mattress took no small amount of savings. I wanted to get it right and my gosh was it agonizing to choose. Such an unreasonable and almost senseless gamble to buy a mattress online without ever testing it in person especially a mattress in a box, typically mass made in china and drop shipped by some third party company that charges multiple times it's actual cost, you know what I mean. Now I typically take careful consideration of negative reviews especially in issues that are consistently reported and for that reason, despite all the stellar reviews on other websites, every mattress within budget had a repetition of negative issues. This mattress seemed the most consistently well reviewed across several websites, and all things considered I was willing to go quite a bit more over budget for something so vital as a mattress. With all that out the way I'll say it now, this mattress has been so much better than I could have hoped for. It's soft, very soft, mostly dues to the extra thick topper but with the support of an actual coil frame. I personally cannot stand foam mattresses, and all the nice spring or hybrid mattresses where just too much. Then again my main concern with hybrid mattresses are the hazardous materials used in manufacturing. They check all the boxes for flame resistance and what have you but the toxicity was not something I wanted to risk. Imagine having to de-gas your mattress and even then the materials aren't going to decide to not be carcinogenic just because you sleep with them. It's isn't verifiable what these offshore manufacturers are using but this mattress is made in the US. I did spent quite a bit of time researching into it's safety and manufacturing and since this is too much already for a simple review, I'll end this by saying: this mattress is sooo comfortable, well made, and safely made. (Just don't jump on it like a fool and complain the support gives out or pile drive the thing with all 400 something pounds of yourself after a long day and then go on amazon to complain when the knit cover starts to inevitably tear. It's still a product that needs to be taken care of just as everything else). ... show more

    • Comfortable and Affordable
Color: White Size: King Pattern Name: 10"
I switched from a total memory foam to this hybrid to provide more support. I have been sleeping on it for a couple months and it has been comfortable. It feels much better on my back than the memory foam mattress I was using. I haven’t noticed any low spots created by where I lay (unlike the memory foam I had). This is just as heavy as my memory foam mattress, so make sure you have it where you want it before breaking the seal on the plastic. Unfortunately for me, this plastic was ripped. So when I opened the box, the mattress quickly expanded and I had to flip it over and push it onto the platform. I’m also using it without a box spring on a metal platform and that is holding up well. Overall, it is more comfortable than what it replaced and provides more support. The price is very reasonable as well. ... show more

    • Great mattress!
Color: White Size: Queen Pattern Name: 12"
We've had this mattress for about 2 years now. We have little complaints. It's a bit on the firm side, but that's the way we like it. It hasn't sacked or developed any low spots. I would not hesitate to buy it again!
