- 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.

This mattress is really wonderfully upgrade to my sleep. I am very picky when it comes mattresses because we are spending 1/3rd of our lives on a mattress. The twelve inch foam design offers the perfect balance of support and comfort. The medium firm design is perfect for those that sleeping on mattress that’s neither too fork not too soft. The packaging was well designed also. It arrived at your doorstep in a single box that can fit through any door. The directions were easy to follow. Remove the plastic layer and let the mattress expand for 72 hours. And wow how much it actually expands! The best thing I love about this mattress is how cool and breathable it is. I don’t wake up sweating anymore. It’s a perfect combination of soft and supportive. From the moment I opened it up, setup was simple. It expanded quickly and didn’t have the string disk smell I was worried about. If you are looking for the newest technology when it comes to mattresses look no further!

This king mattress is incredibly comfortable and provides great support. The medium firm feel is perfect, not too soft and not too hard. I really like the hybrid design because the memory foam relieves pressure while the pocket springs give solid support. It does a great job with motion isolation, so movement on one side doesn’t disturb the other. The mattress expanded quickly after opening. I’ve noticed much better sleep and less back discomfort since using it. The edge support is strong and doesn’t sink when sitting. It feels well made and high quality for the price. Over This mattress is an excellent value and I would definitely recommend it.

I’m really happy with this mattress! It’s comfortable, supportive, and I’ve been sleeping so much better since I got it. The material feels high quality and it expanded quickly with no smell. Not too soft, not too firm—just perfect. Great value for the price.

For a Amazon mattress I actually only have a few honest complaints, it does fit queen sheets well except it doesnt quite fit for all bed frames it’s hit or miss consider buying a larger bed comforter to fill in any extra space between your bed and frame it runs a bit small for American queens the texture of the fabric overlaying the bed will get stained easily and it’s hard to clean in between all of the crevices since it’s a more wrinkly texture keep in mind if you have small children, the comfort of the mattress is above average the spring foam hybrid style has improved my lower back pain within weeks of use! the noise level is nonexistent you do feel other movement throughout the bed if another is moving on it except it’s less noticeable then a normal spring mattress but I do feel the overall quality for $260 is a great deal for a mattress of a queen size delivered in a box I was worried about the bed sitting to long in the warehouse and the memory foam not expanding correctly you may be thinking the same but my mattress was of top quality no trouble inflating if anything it inflated faster then 72 hours.

I have been sleeping on this for a few months now, and I am honestly shocked at the quality. As far as I'm concerned, this feels just as good as the $1,000 name-brand beds I've tried in stores. The comfort level is spot on. It hits that "medium-firm" sweet spot perfectly it’s supportive enough that you don't sink in too far and hurt your back, but it has enough plushness on top to feel luxurious. If you are on the fence about buying a mattress in a box, don't be. This is an incredible value for the bedroom.

This king size mattress is so comfortable. Easy to set up with instructions, just took out from the box and jet it inflated for around 24 hours .It is medium firm , but still provides enough support to your back . It really help me ease my backache a lot. The material of the mattress met my expectations compared to its price. Definitely worth it
