  • Foam mattress
Color: White Size: Queen Style: 10 Inch
This is my 2nd time purchasing foam mattress from Amazon. I got a different brand last time. This foam mattress is great, sold by Amazon company. This foam mattress is not soft, it's more like medium to firm mattress. If you are looking for a soft foam mattress, don't buy this one. I work at the restaurant everyday and am looking for something medium to firm foam mattress helping soothing my back muscle, therefore this one works perfect for me. Had been sleep on this mattress for 2 weeks and feeling good the next day morning. Quality is good and it came as compressed and it does need a few days to be fully expanded to normal size. Fabric is smooth as week. It's great value compare to other expensive Americans brand mattress. ... show more

  • So far so good
Color: White Size: King Style: 12 Inch
We just opened it today. I will try to keep updating this as we have had it. There was no smell. It has been sitting for less than 12 hours. There is one side where the corners are taking a while to come back to shape but so far feels like it will be a good bed. Coming back 48 hours later to say that the bed has fully expanded and it is soooo comfortable. We did pull on the corners throughout the 48 hours to help/make sure they popped out because some of the reviews had me worried they wouldn’t pop out on their own. It is more firm especially when you’re first laying on it but as you lay on it you just slightly sink in and it cradles you! I think we currently have it on the firm side. My SO prefers firmer mattresses and he loves it! Hoping it stays nice. Will add to review as time goes on. ... show more

  • Sleep like a dream
Color: White Size: Queen Style: 8 Inch
It’s super comfy and provides just the right amount of support, which is perfect because I like my mattress not too hard and not too soft. The size is great for my space, and it feels like it hugs you into just the right sleep posture. I’ve had some of the best sleeps of my life since switching to this mattress, and waking up without the usual back pain has been awesome. Setup was a breeze too, which is always a plus. If you’re looking for a solid, comfy mattress that won’t break the bank, this one’s a winner! ... show more

  • Nice mattress
Color: White Size: Queen Style: 12 Inch
Nice mattress. It definitely takes some getting used to sleeping on this type of mattress. It’s very important to make sure you have it flipped on the correct side that you want. It does take a couple of days for it to expand to maximum thickness. Overall I get a good nights sleep.

  • Uncomfortable
Color: White Size: King Style: 10 Inch
This mattress was comfortable for the first couple of months and then my back starting hurting so bad every night. This mattress is very firm, a lot firmer than I had expected it to be. I have only had this mattress for a little over a year and already had to buy a new one. Don't waste your money!

  • Disappointed… comfortable, but not firm AT ALL
Color: White Size: Queen Style: 12 Inch
Update- purchased for use in an Airbnb and people seem to really like it. So I’m updating review and rating. IT IS VERY SOFT & PLUSH. I do like that it can be flipped and it expanded to at least 12”, maybe more… In the description, it was described as medium firm on one side and firm on the other. This is not the case at all. I don’t believe that it’s memory foam either. It is very soft. A large person will sink A LOT on this mattress. I have two others that are firm. One hybrid and the other is all foam. I don’t sink much at all on those. This one I sink in a lot, which I don’t care for. This mattress is fine for people under 150lbs. If you weigh 200+ I would not recommend this mattress, unless you want a really plush mattress that you sink in a lot, that isn’t actually memory foam. It actually sleeps okay for a night or two, I just describe it as plush… but if you have back problems and want support, this is not the mattress for you. Considered returning, but it’s for guests and we haven’t had any complaints. But I would not recommend or buy again. NOT AS ADVERTISED. ... show more

  • Decent mattress
Color: White Size: Queen Style: 12 Inch
Had my first night on it. Scored 100% on my sleep tracker which is great because usually I only score 80-90%. No smell. Feels very comfortable! One side is more firm, but tonight I think I slept on a softer one. I think it’s good value for money. It inflated pretty fast. I only waited around 16hours before sleeping on it. Some corners were still being inflated but it didn’t matter to me, I think in the morning it already looked complete. We’ll see how it’ll hold up, but so far so good! ... show more

  • Delivers firmness without sacrificing comfort
Color: White Size: Queen Style: 12 Inch
After years of disappointment with coil mattresses from various brands, my wife and I decided to explore the realm of foam mattresses in search of the back support we desperately needed. One of our primary concerns was finding a mattress that offered firmness without sacrificing comfort. From the moment we laid down, it was evident that this mattress was different. Despite our initial skepticism, the foam construction provided an unparalleled level of support that surpassed our expectations. Additionally, we appreciate the absence of unnecessary pillow tops—a feature that tends to compromise the integrity of many mattresses. With this mattress, what you see is what you get: pure comfort and uncompromising support. We are so happy with this purchase. If you're like us, in search of a mattress that delivers firmness without sacrificing comfort, look no further than a foam mattress. It's a decision you won't regret. ... show more
