Features
- Precision Support & Comfortable Sleep: UltraSnooze 12 inch king size mattress combines the precise support of individually pocketed springs with the softness of premium memory foam. It adapts to your body's contours, evenly distributing weight to effectively relieve pressure points and help alleviate physical fatigue and soreness. It helps you drift off effortlessly, ensuring restful sleep throughout the night and significantly improving overall sleep quality.
- Breathable Comfort: The king mattress features premium knitted fabric that feels soft against the skin and offers excellent breathability, effectively preventing nighttime stuffiness for a cool, airy sleep experience. Memory foam and individual pocket springs work together to enhance airflow, quickly wick away moisture, and prevent heat buildup, maintaining a cool and comfortable sleeping environment. This mattress is particularly suitable for those prone to sweating or with sensitive skin.
- Motion Isolation & Edge Support: The 12 inch hybrid king mattress features individually pocketed springs and zoned silent technology to effectively absorb vibrations and noise from turning over. Even if your partner gets up or tosses and turns at night, you can still enjoy deep, uninterrupted sleep. The edge reinforcement support technology can effectively prevent the mattress from collapsing and sagging, avoid the risk of edge sliding, and provide long-lasting and stable support.
- CertiPUR-US & OEKO-TEX Certification: UltraSnooze 12 inch king bed mattress features a fiberglass-free design and holds both CertiPUR-US and OEKO-TEX certifications. Free from harmful substances in your sleep environment, it safeguards your health and safety. We offer a 365-night comfort trial and a 10-year limited warranty. The hybrid mattress provide you with a safe, non-toxic, and comfortable sleep experience.
- King Mattress in a Box: The 12 inch hybrid king size mattress is shipped compressed and rolled for easy handling and installation. It fits most bed frame types, including flat beds, box spring beds, platform beds, bunk beds, floor beds, slatted beds, and hospital beds. Allow the mattress to fully expand and rest for 72 hours to achieve optimal support and comfort. Our boxed design facilitates passage through hallways and doorways.

Super comfortable mattresses and of excellent quality The mattresses are very comfortable, with the perfect firmness to sleep well without back pain. My daughters rest a lot and no longer wake up with discomfort. The surface feels soft but with good support, and they keep their shape after weeks of use. In addition, they do not have strong odors when unpacking, which is very much appreciated. They look well made and durable for the price they have. Definitely a great purchase if you want comfortable and good quality mattresses 👍

After using this mattress for some time, I can confidently say that this is the best mattress I have ever bought for my home. With the perfect balance of firmness and softness, this mattress provides excellent support for shoulders, lower back, hips, legs and more while remaining comfortable. I will never be tortured by my old mattress again. This mattress was also very easy to install. The mattress expands to its maximum capacity within 72 hours, has no odour and is ready to use right out of the box. This mattress is much cheaper than similar mattresses I've tried in shops, but it performs just as well as the same model that sells for twice the price. For those who are hesitant to buy a mattress online, this mattress delivers what it promises - perfect comfort, high quality construction, and excellent value. It has totally improved the quality of my sleep and I would not hesitate to recommend it to friends and family.

Delivery was quicker than expected and the mattress was received in excellent condition. I was pleasantly surprised by the fact that the mattress had absolutely no memory foam smell and was literally ready to use straight out of the box. The comfort level of the mattress is perfect, achieving the ideal balance between support and softness. Since I started using this mattress I have woken up every morning feeling refreshed and very comfortable. I also really appreciate the fact that it does a great job of motion isolation and doesn't wake up the kids and my partner when I get up in the middle of the night. I can confidently say that this mattress is of good quality at a low price. It is supportive enough to keep the spine in the correct position and provides plenty of comfort whether you are lying on your side or prone.

Will return with an update of durability but for the price and feel it is so far worth it. It is very firm the edges do sink a bit but the person using it is 6’1 and 225.
