Color: White Size: Twin Style: 6" Cooling Pattern Name: New Small Box
No one asked me to write a review on the mattress. This was delivered last night, right on time. It was rolled up tightly inside a lengthy box with the air sucked out. It was very heavy. I needed another mattress for my Lazy Boy couch. This one was the right size and could not believe how well this is made, I could not feel those bars underneath. The price was also very decent. There was no smell, the instructions were very well written, there was no sinking way down, the comfort was perfect. Thank you! ... show more

    • great purchase
Color: White Size: Twin Style: 12" Cooling Pattern Name: New Small Box
It's only been a week, but I wanted to make sure I got down my initial thoughts. The mattress quality is well worth the price. I opened the box and let it fluff up in the early afternoon of my moving day, and it was ready to sleep on by evening. the cover looked nice and well made. The mattress is a little firmer than I would have purchased if I had tried it before buying, but its also squishy enough that I don't mind. I am a hot sleeper and I haven't had an issue with feeling heated from the mattress, so that's good. It does sink quite a bit when you sit on the edge, but all foam mattresses do to some extent. Honestly, if it lasts me 4 or 5 years, I will have gotten my money's worth and then some. ... show more

    • Great little mattress.
Color: White Size: Twin Style: 8" Cooling Pattern Name: New Small Box
I looked all over for a mattress for my teenager. After many read reviews on multiple products this is the one we found best suited for her. It was super easy to set up, Fluffed up nicely and within mins. It seems to be well made. It’s the firmness she wanted and it’s extremely comfortable. She’s an active sports kiddo and she sleeps so good on this compared to what she had. The cooling function is eh, she gets hot easily with it and there is No cooling happening. Not sure what we even expected from that .This is the only thing wrong with this mattress. This would make a great bed for any kid or toddler or even an adult or to even be used in a spare bedroom. You can’t beat the price of this mattresses. I hope we get a few years out of it. ... show more

    • Firmer than I expected
Color: White Size: King Style: 12" Cooling Pattern Name: New Small Box
I bought this mattress after staying in an AirBNB that had the same one. In the rental, it was super comfortable and just the right mix of firm and soft with a thin waterproof mattress cover on top, but when I got it at home and used the same mattress topper the bed is much firmer. I "broke it in" as best I could by walking on it and have slept on it for over a month, but the firmness stays just as it did when I got it. I'm going to keep it because its too much of a pain to return, but I'll need to add a mattress pad to give relief to my hips when I sleep on my side. Positives: the movement of your sleeping partner isn't felt at all, there was no odd smell, it expanded to the size I expected, I was able to get it up the stairs and unrolled by myself with some creative moves (I'm 50, female and have average level of strength). ... show more

    • Very good mattress. Good company
Color: White Size: Queen Style: 12" Cooling Pattern Name: New Small Box
I have a severe latex allergy and this brand is one of a few that make their mattresses completely latex free. My first mattress I had (12 inch full) lasted about 6 years before it started to sag. My hubby and I decided it was time to upgrade so we got the 12 inch queen and oh my gosh it is amazing. It was easy to install on the frame and sinks a bit on the sides but every mattress I’ve owned does that to an extent. Well worth the price. It is firm but not so much that it causes problems. Very comfortable and spacious ... show more

    • Very comfortable. Great value
Color: White Size: Queen Style: 10" Cooling Pattern Name: New Small Box
I did a lot of research before purchasing this mattress. I care about my sleep a lot and I know there are many cheaply made mattresses but sold at high prices on Amazon. This mattress is genuine. True to the description. And having slept on it for 2 months now, I can honestly say very comfortable. Never had any back issues or soreness in the morning. It as good circulation, and doesn't get stuffy and too warm in the night. I'm very, very happy with it! ... show more

    • Adequate. Not uncomfortable.
Color: White Size: Queen Style: 12" Cooling Hybrid Pattern Name: New Small Box
This bed is acceptable. It is indeed cooling, almost too much so, but it’s winter now, so I imagine I’ll love it in summer. It's very firm, not medium firm, but I like the level of firmness and bought another Zinus knowing it would be firm. It expanded quickly and is the full 12 inches. It’s bouncy, but in a nice way. The memory foam topper is comfortable. Structurally, it’s not the best- the foam can move, so I find it’s pushed out a tiny bit further on the sides not against a wall. I can easily feel the springs through the sides, as it’s just thin fabric. However, I do not feel them through the top and sleep comfortably. I understand those who complain about rolling off, though I do not have that problem. It just doesn’t have firm sides due to the foam. I would not recommend this particular mattress for those structural issues, though I would recommend the green tea foam one. However, I’m satisfied with it and will keep it. My back pain is improving, and it’s only night number 2. It’s very affordable, so make your decision accordingly. ... show more
