- 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: Our medium firm 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.

The mattress is a great deal, super economical, arrived within a day and expanded pretty quick within few hours. It looked bigger in width than described which is a good thing. My sleep quality has dramatically improved and my backache has gotten better because it is pretty firm. Seems pretty durable and functional especially for the price. A must have.

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 .

For the price this is a great mattress. Absolutely no odor. We waited the 72 hours; however one corner still did not fill in properly. (Small patch on corner laying more flat) Not a deal breaker as it was purchased for my daughter’s room and it does not interfere with comfort or aesthetic. The comfort of the mattress is nice and feels firm yet plush. However, the edges of the mattress remind you that it is a box mattress as you can feel every spring. As others have warned, careful when opening…it pops open quick and can knock you down. I thought I was going about it ok but made the mistake of getting caught between it and the bed rails…daughter was laughing so hard she couldn’t help me. Just know that once the plastic is about halfway ripped, game on. It will rip the rest of the way itself and take anything down in its path 😆 haha.

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

Surprisingly comfortable, and good quality bed. I was in a situation where we my husband thought he had indigestion and ended up needing a double bypass. He was in the hospital for a week, and stairs were going to be a no go for a while, so I had a week to redo the guest bedroom. I ordered this bed after researching and reading the reviews and I was pleasantly surprised by how accurate they were. Pros: The shipping was FAST. Got this thing in two days. The bed is super compressed so it made it a breeze with a lifting buddy to get it in the house and unwrap. Oh, be careful opening; im not small, nor overly large and when I cut this thing open, it LITERALLY unrolled so quick and powerfully, it shot me clearly to the far wall of the room. But that was my bad; physics and all that are not my strong suit and at least my son had a nice laugh. Nothing was harmed but my pride. This is truly a comfortable bed. It IS in fact a very fine compromise between soft and firm. In fact, id say firm isnt the word that should be used so much as substantial; it feels solid, like youre not going to fall through, and clearly you won't have dents in it inside of six months. Its actually quality. Cons: The only real con I have is that I'd agree with all reviews that say that the edges aren't as firm as one might like. You do seem to sink down a bit farther than normal if you decide to sit onnthe edge and say, put your shoes on or something. Its not a deal breaker though; My husband was able to get in and out of bed with ease, and as our upstairs bed is a Select Comfort, he said this bed made him want to go back to spring and coil beds. And he likes to sleep firm, so that's a compliment for the sturdiness of this bed. All in all, I'd say this is a fine bed and really great for the price.
