- Upgraded Support for Stable Sleep & Durable Resilience- Engineered for superior support and lasting performance, this 12 inch king size mattress features a synergistic blend of high-density support comfort foam and a firm stable support foam. This dual-layer support core delivers reinforced, medium firm support to resist excessive sinking and deformation, so the foam mattress maintains its excellent support and structural integrity for years of daily use.
- NanoGEL Foam for Spine Alignment & Pressure Relief- Featuring adaptive NanoGEL memory foam that precisely conforms to your body's contours, this king mattress effectively relieves full-body pressure. Combined with a dual-support core, the mattress promotes optimal spinal alignment and supports neutral sleep posture. Its targeted support eases back and waist stiffness, making it an ideal choice for back sleepers.
- Temperature Control for Restful Nights- Stay cool and comfortable from dusk till dawn. Our innovative Cooling NanoGEL Memory Foam is infused with thermally conductive gel particles that actively draw excess heat away from your body during sleep. Paired with a breathable knit cover that enhances airflow, the king size mattress memory foam prevents heat buildup, night sweats, and restless tossing, keeping you comfortably cool all night.
- Motion Isolation for Undisturbed Tranquility- Perfect for couples and light sleepers. The all-foam construction acts as a natural shock absorber to minimize motion transfer. When your partner is tossing, turning, or getting up, our king foam mattress effectively reduces motion transfer and dampens noise, creating a quiet, stable sleep surface that lets you enjoy deep, undisturbed sleep throughout the night.

Back & Side Sleeper w/ Back Pain? Try this Mattress!
Color: Grey
Size: Queen (U.S. Standard)
Set name: 12 Inch
I absolutely love this mattress. It started when I ordered one for my son’s bottom bunk bed. . . I laid in it and knew I needed one; I joked with him saying my seven year old has a nicer mattress than his parents. So I came back and bought a queen for one of our guest rooms where I sleep. I have never slept better. My favorites: the mattress rebounds fast when you get up. It is very soft, but also firm enough to provide proper support for my back and neck. It is not so soft though that I have difficulty turning sides at night - I’m a back and side sleeper. It is OKEO-TEX certified, so no nasty off-gassing of toxic vapors. Couldn’t be happier with this purchase!

Very Good For Joint Pain, But Appearance Isn't Great
Color: Grey
Size: Queen (U.S. Standard)
Set name: 12 Inch
Medium firm but more to the firm side in the best way possible. With constant joint pain from Fibromyalgia and Elhers Danlos Sydrome (loose joints that dislocate often), I'm very sensitive to mattress firmness. It can't be too firm or I hurt like I slept on the forest floor. But too soft and everything slips out of place and I can't move the next day because too many joints won't support me. I researched for a few hours to find a good mattress for these things AND that would keep me cool (heat intolerance is so much worse in this pregnancy). We had a hybrid mattress before and I was nervous to try fully memory foam, but I'm so glad we did. This is easily the most comfortable mattress I've ever imagined! I lay down and within a few seconds (everytime, no joke) feel my entire body realign and have multiple joints pop into place. My chronic pain is much more manageable with this and laying down resets my system much sooner than our old mattress ever did. By the end of the night, my big pregnant belly has a cozy nook in the mattress since I can't get myself to sleep not on my stomach, even now in the 3rd trimester. But it doesn't hurt or tick the baby off because the mattress just makes space and supports the rest of me perfectly! I don't feel the need to relocate from a "hot spot" because it doesn't get hot or even very warm. It isn't cold by any means, but it sure doesn't hold heat like most mattresses, which is a win! My poor husband puts up with the crazy cold temperatures I need in the house, and is not bothered by the cooler mattress despite NOT liking the cold! My only problem is that after unrolling and unfolding the mattress, one half stayed wrinkle-warpped on the surface. So one side is smooth fabric top, and there's a clear line where it was folded and the fabric was pressure folded as it got rolled, and it is still rippled about an inch above the mattress in a dozen or more lines across. It's not too noticeable when laying on the sheet, but you can see the ripples through the sheet pretty easily. I can manage with the appearance and feel, but it is frustrating

⭐⭐⭐⭐⭐ So glad I gave it the full 72 hours!
Color: White
Size: King (U.S. Standard)
Set name: 14 Inch
⭐⭐⭐⭐⭐ So glad I gave it the full 72 hours! We are very happy with this mattress! One thing I definitely recommend is giving it the full 72 hours to expand before deciding how you feel about it. At first, it felt softer than I expected and I was a little worried it wouldn't be firm enough. As it continued expanding and settling, though, it became noticeably firmer and more supportive. My husband is 6 ft 2 and 220 lb he normally hollows out mattresses this mattress can support him and I'm not affected when he rolls over or sits I can't tell when he's moving. The 14-inch height feels substantial, it's comfortable without feeling like you're sinking too far into it, and the king size expanded nicely. For the price, I'm really impressed with the quality and comfort. If it seems a little too soft when you first open it, give it time, it really does change as it fully expands! Definitely a 5-star purchase for us.

Very comfortable and Great Deal
Color: White
Size: Full
Set name: 12 Inch
Got this in today, it rose quickly once opened but the smell was attrocious. It filled the whole to floor of our home. It's a relativity soft mattress. Seems like it will be ok for our daughter who we got it for from a firmness, but if am adult were to lay on it, it would sink pretty far. Hoping that this smell won't last forever... Will update in a week or so. UPDATE: mattress sleeps great. The smell never fully went away, but the supplier reached out and sent a replacement from a different warehouse which seems to have been the ticket. This new one does not have the pungent odor that I experienced with the first. Thanks for your customer service!

Give it time…
Color: Grey
Size: Full
Set name: 10 Inch
I originally wrote a scathing review because I thought the bed was too soft. That was within the first 24 hours. A week out, it’s now perfect. So give it time because it does firm up. It is as others have described: firm, but not too firm. I did put a nice soft and plush mattress pad/protector on it, but otherwise it has not needed any extra additions. Had I fully believed the reviews I would have gotten the 12 inch. I went with the 10 because I figured it would need a soft gel pad to soften it up some, ultimately making it 12 inches. Nope, it’s perfect so now my bed sits a little lower than I would prefer. But hardly a big deal since the mattress is comfortable, and at a reasonable price.

Great support and stays cool
Color: Grey
Size: Queen (U.S. Standard)
Set name: 14 Inch
I’ve had this a month now. Some reviews are saying this is a semi firm mattress but I consider it firm. I find it supportive but I don’t sink into it. I’m 6’2” and 250 lbs. Smaller people fill find this more firm than I did. The mattress returns to shape each time and I have no indentation in it even though I sleep on the same side each night. I don’t like being warm so this mattress works for me. I don’t get over heated. I also have a mattress pad on it with bamboo sheets. So far I’m happy with it.

Decent!
Color: Grey
Size: King (U.S. Standard)
Set name: 12 Inch
I’m giving this mattress a solid 3 due to the fact that it is a true king size. It measures at exactly 11.5 inches not the full 12. I let it rise for the recommended 24-48 hours. The appearance is nice. It has a cotton mattress protector that is removal for washing which was nice. I haven’t felt any cooling features so far. The feel?! It’s firm!!! I don’t know if they accidentally sent me a firm but this mattress is definitely not medium firm it’s firm. It doesn’t have the edge support as advertised so I’m sure it’ll break down with edge sleeping and/or sitting. It hasn’t helped my back nor shoulder pain. It doesn’t seem to offer much pressure point support but it could be because it’s still fairly new (only had it 3 weeks so far)! If you love a firmer feel, this is the one for you. Maybe it’ll soften up and feel more medium firm but after 3 weeks, it’s still firm so I guess I’ll wait and see and come back and update my review. The three stars is for the softness of the material used, the fact that it at least hit 11.5 cuz IYKYK how mattresses can be with sizing, and the fact that it fits a king bed as it should and once again IKYKY!

Comfortable moderate priced mattress
Color: Grey
Size: Full
Set name: 10 Inch
Great mattress! I gave it 72 hours to rise to exactly 10 inches. Super comfy, soft - not hard. A bit of a smell (which is noted in the package) but I left the bedroom windows open while it expanded which eliminated the scent. I especially love that it's gray.
