  • Must Buy!
Color: Blue Size: King Style: 12 INCH-NEW
I’ve tried a handful of “high-tech” mattresses—cooling gels, memory foams, you name it—and they always felt gimmicky and quickly lost their shape. This one from Amazon is by far my best mattress purchase ever. It hits that sweet spot between soft and firm: just enough cushion to cradle your shoulders and hips, with the right amount of support so you never feel like you’re sinking in. The cover has a subtle, modern pattern that elevates the look of the bed (even if you’ll never see it under your sheets!), and the construction feels solid—no sagging or pancake-flat spots after months of use. I wake up refreshed, without any back or shoulder aches, and it still feels brand-new every night. If you’re tired of mattresses that promise the moon with fancy technology but fizzle out, give this one a shot—perfect balance, lasting support, and total comfort. ... show more

  • Great Value and extremely comfortable.
Color: Blue Size: King Style: 12 INCH-NEW
Ive had this bed for almost a year and its held up great, even though im upset its like 100 dollars cheaper now. This bed feels great on the back and it contorts to your body like a glove. Its firm but not too firm, just enough softness to sink a little hugging your body. Im 6'1 and about 250 lbs and its absolutely perfect for me. The only con id say is because im bigger this bed retains quite a bit of heat so during the summer months use less blankets because you might wake up sweating like i did occasionally, for smaller individuals this might be a big plus though. Im lucky because I live in the PNW so I only got to worry about that for like 2-3 months out of the year. My gf, though, did have one con and it didnt effect me like it did her but shes really sensitive to dust and other allergens. This mattress seems to pick up dust and retain it in its blue fabric underneath causing her to sneeze and have bad allergies, it only happened when she slept on this bed, the room is clean and I even have an air purifier, but still, whenever she was on the bed it seemed to effect her so if you are really sensitive to that kind of thing (and if the bed is in a room with longer carpet like ours was where allergens are prevalent) i'd look elsewhere. But all in all for me its an amazing bed and really well priced. ... show more

  • Anti-displacement effect
Color: Blue Size: King Style: 12 INCH-NEW
The mattress as a whole is still very beautiful. It is very comfortable to lie down and try it. It is very cost-effective and worth the money at this price. The quality of the goods is particularly comfortable, practical, breathable, not sultry when sleeping, full of elasticity, feeling that the golden body can hold it, the waist and spine can fit well, and the sleeping feeling is great. The mattress is good, very thick and comfortable to sleep, recommended! ... show more

  • Very good in both comfort and support (and cheaper than other brands)
Color: Blue Size: King Style: 12 INCH-NEW
My wife and I bought this after a friend suggested this model. In terms of firmness, on a scale of 1-10 with 10 being the firmest, it's probably about a 7. It's actually soft, but you can tell quickly that it's not super soft like a hotel mattress. We wanted something that was not like a hotel bed because I had lower back pain from an injury. Overall, this mattress sort of covers both areas of being soft and supportive. Some people may need more support than what this provides, and some people might want more softness. For those who want a bit of both, this does it well. I don't wake up and shift positions frequently from discomfort with this mattress, so that's a benefit I appreciate. The price for value is also quite good. We actually spent much more money on a mattress from Costco that wasn't better in terms of quality. The Costco mattress was too soft, so we looked at this option among others. In terms of smell, there really wasn't much of any, which is what I prefer. Just a very subtle plastic-like smell for a day or so. Considering the price, which was about $300 less than other mattresses we bought in the past, we're quite satisfied with it. ... show more

Expanded really good it feels like sleeping on clouds it's not too firm but firm enough to where you won't sink in I'm honestly surprised I thought it would be a little thinner but it's very thick which is awesome
