Features

  • CertiPUR US Hassle-Free Purchase: AN Adamant Noyau mattresses prioritize your health and safety, all memory foams are certified and tested by CertiPUR US to ensure that the products are free of harmful substances and meet the highest quality and safety standards, allowing you to enjoy a comfortable sleep on a fresh and odorless mattress.
  • Zonal Support Design: AN Adamant Noyau 12 inch hybrid king mattress adopts an ergonomic design with a zonal support system to provide differentiated support for different parts such as shoulders, waist and legs, ensuring that the spine maintains a natural curve, while the rapid rebound of the spring can effectively relieve pressure points.
  • Stay Cool and Sleep Naturally: The 12 inch king mattress is made of highly breathable fabrics, which can effectively promote air circulation inside and outside the mattress, quickly discharge moisture and heat, and keep the sleeping environment dry and comfortable, suitable for people who are prone to sweating or sensitive to temperature. At the same time, the use of breathable materials further enhances comfort and health.
  • Fit the Human Body, Sleep Freely: AN Adamant Noyau mattress adopts a high-density and high-resilience independent pocket spring system, each spring operates independently to provide precise support, the upper layer is a soft rebound layer, and the lower layer is a strong support layer, which can not only provide a comfortable fit, but also ensure that all parts of the body can be evenly supported, effectively prevent the body from sinking, and maintain a natural posture during sleep.
  • Movement Isolation, Undisturbed Sleep: The spring system of the AN Adamant Noyau mattress is dynamically responsive, adapting the support force in real time to body movements and pressure changes, ensuring optimal support and rebound whether you are lying on your side, back or stomach, improving your sleep quality. At the same time, the high resilience of the spring effectively reduces the interference when turning over.
  • Tips: We recommend that you open your mattress and wait 72 hours for the mattress to fully inflate for the best sleeping experience. If you have any questions, please contact our friendly customer support team.

  • Firm, supportive and surprisingly cool!
Size: King (U.S. Standard)
After trying some of the costliest mattresses over the years, I can confidently say this hybrid mattress stands out as the best I’ve used so far. I’ve been sleeping on it for about 10 days now, and here’s my honest experience: 1. **Cool and Breathable**: I'm prone to sweating at night, especially in warmer environments. This mattress feels noticeably cooler and more breathable, which has been a huge plus for me. 2. **Perfect Balance of Firmness and Comfort**: Unlike other mattresses that tend to sag or sink over time, this one feels firm yet soft on the surface. It offers a solid feel without compromising on comfort. While it’s still early to judge long-term durability, so far it holds its shape well. 3. **Undisturbed Sleep and Easy Movement**: One of my biggest issues with previous mattresses was the effort it took to turn or shift during the night. This mattress allows easy movement without any pressure or disruption, helping me sleep more peacefully. 4. **Great Support for Back and Joints**: I have ongoing back issues, so I needed something that offers proper spinal support. This mattress provides excellent support to my back, shoulders, and legs equally, and I’ve noticed a significant improvement in how my body feels in the morning. 5. **Solid Base Support**: The lower layers seem to offer strong foundational support, which helps maintain proper alignment and stability throughout the night. Overall, I’m genuinely impressed with this hybrid mattress. It’s exactly what I was looking for—cool, supportive, comfortable, and easy to sleep on. I highly recommend it to anyone looking for a firm yet cozy mattress that supports ... show more

  • Comfy!
Size: King (U.S. Standard)
Have been looking for a mattress for some time and the only thing i could find for the price of this one are the firmest mattresses comparable to sleeping on a sheet of wood. This is far from that. The thick memory foam padding makes you feel like you are comfortably sinking into a cloud, the foam support beams also make it sturdy enough that you don't feel like the mattress is swallowing you whole. It is extremely comfortable and i dont feel hot or sweaty at night. What i also appreciated is the boxing. It cones in a super thin rectangular box, which was important because i was moving into a new place and did not want extra costs to move this thing. It fit in my sedan. It is super easy to assemble, just open the box and let it soak air as it is completely compressed. The box did weight about 100 lbs though lol and there was a smell at first but after a fee days it went away. ... show more

  • Comfy mattress all around
Size: King (U.S. Standard)
I’ve been sleeping on this mattress for a week now and it’s been a game changer. It’s super supportive but still soft where it counts, and I don’t overheat like I did with my old one. I wake up feeling way more rested, and my back pain is noticeably better. I’d like to mention that this was in fact extremely simple to setup even tho it’s heavy with help you just simply put it on your bed frame and cut it open and let the foam rise to its original shape. I sleep cooler at night, and I don’t feel my partner moving around at all. Definitely the best sleep I’ve had in a long time. The support is great because it has more support then a traditional all foam mattress which is nice for someone such as myself that appreciates a firmer mattress rather then something super soft and plush. It’s also I’d like to add the perfect height for my bed frame and bedroom. Overall I’d highly recommend this mattress to anyone looking for something of high quality and also a great price . ... show more

  • Great upgrade from my previous mattress!
Size: King (U.S. Standard)
It’s amazing that they can squeeze a large king size mattress into a relatively small box. I’d advise you to remove your old mattress and get this one in position before you open it. Once it is open I really like the handles that they have put on the sides of the mattress, to help you move it around. Comfort is much better than my old mattress that cost a lot more than this one. I usually get up a couple of times during the night so I really like the independent spring design so as not to disturb the other person. Certified by CertiPUR-US means that the mattress is not made with harmful materials. The outer fabric is a breathable material to help keep you cool through the night. I was concerned about my sheets fitting but they easily fit this mattress just fine. Overall pleased with this mattress ... show more

  • No smell but it said to allow 72 hours to inflate but it seemed to inflate good after 13 hours.
Size: Queen
We've had this before for 3 weeks now and we both love it. It's not to soft or hard for either of us and we have slept really good on it. If I could change anything I would get a 11" instead of a 12". I'm 5'5" and with my 12" box springs it's a little high but I can get in it so we're happy in all. I will give another review next May after sleeping on it a year. Hopefully it will be great for many years. ... show more

  • Good sleep!😴
Size: King (U.S. Standard)
I recently purchased this King-size mattress, and it’s been a game-changer compared to my old memory foam bed, which was overly firm and uncomfortable. This new mattress features individually pocketed spring coils that provide excellent support without feeling rigid, paired with a layer of soft, cooling memory foam that cradles you just right. The cooling technology actually works—I no longer wake up feeling hot. Setup was a breeze, and it’s been incredibly comfortable for both me and my partner. Perfect balance of support and softness, highly recommend for anyone looking to upgrade their sleep! ... show more

  • Great Mattress, but Be Careful Unpackaging!
Size: King (U.S. Standard)
Amazing quality for the price! Love how thick and comfy it is! Already ordered a second one for our other guest room. Just be sure to read the instructions for unpackaging the mattress. We did not and I was knocked over by the mattress as it rapidly unfurled after cutting away the plastic with scissors... we later found it came with a razor blade tool for this purpose, which would have been much easier... also later saw the directions, which were tiny and hard to read, but would have prevented that from occurring. Luckily I only have a bruise on my arm, but it could have been much worse! ... show more
