Features
- The DCOOLAULTRA hybrid mattress is designed with innovative materials, featuring four layers of different foams. The combination of gel memory foam and comfort foam helps distribute pressure and contour to your body. As you sink deeper into the mattress, the pressure-relieving foam becomes firmer, providing you with a unique sense of comfort.
- Highly breathable and cooling: The mattress is made with finely woven, breathable fabric that allows air to flow freely, effectively dissipating steam and sweat from the surface to keep your body comfortable and dry all night long. Additionally, the increased foam content and egg-crate foam structure, with its numerous breathable openings, enhance airflow throughout the mattress, preventing heat retention and ensuring you stay cool throughout the night.
- Enhanced Responsive Support: The DCOOLAULTRA hybrid mattress uses more elastic materials, with enhanced coils and additional lumbar foam working together to provide stronger support. This helps prevent the hips and lower back from sinking, keeping the spine in proper alignment. It offers extra pressure relief, assisting in alleviating back pain every night.
- Zero Motion Transfer, No Disturbance: The core of the mattress features the most advanced pocket spring system, with each spring encased in its own fabric pocket to prevent tangling. This design ensures zero motion transfer, so whether you're sleeping alone or with a partner, you wont be disturbed. Reinforced edges allow you to enjoy every inch of the mattress without worrying about rolling off.
- Safe Materials and Worry-Free Warranty: All memory foam is CertiPUR-US certified and tested, and we offer a 10-year warranty. We recommend allowing your new mattress to fully expand within 72 hours. Please maintain a safe distance when unboxing, as the mattress may expand quickly and pose a risk.

The media could not be loaded. This mattress has been a big upgrade for me. The surface has a nice balance of softness on top with steady support underneath, which makes it comfortable without feeling too firm. I sleep mostly on my side, and I’ve noticed less pressure on my shoulders and hips compared to my old mattress. It came well-packaged, expanded quickly, and didn’t have much of an odor after opening. The edges hold up better than I expected, and the materials feel reliable. I also appreciate that it doesn’t trap much heat — I stay cooler through the night, which has made my sleep more consistent. For the price, it delivers very good value. If you’re looking for a mattress that combines comfort, support, and quality at a fair cost, this one is worth considering.

The media could not be loaded. Got this mattress 5 days ago and it's been great so far. Arrived well-packaged and expanded super fast - no weird chemical smell which was nice. It's definitely firm but still comfortable, gives good support without feeling like you're sinking in. I'm a hot sleeper and have noticed I'm sleeping cooler than before. The pocket coils do have a slight bounce to them, which took a little getting used to, but honestly it doesn't bother me much. My partner moves around at night and I barely feel it on my side. Best part is I've been waking up without my usual lower back pain. It's not the most luxurious mattress out there, but for the price and the 10-year warranty, it's doing exactly what I need it to do. Solid buy if you're looking for a supportive hybrid that won't break the bank!

The media could not be loaded. I was a little skeptical about ordering a mattress online, but this one exceeded all expectations. The medium-firm feel is perfect — supportive enough for my back but still soft with the memory foam top. It arrived well-packed and expanded fully within a few hours. No fiberglass, no weird smell, and CertiPUR-US certified gave me peace of mind. I’ve been sleeping through the night without any back pain since switching. Highly recommend if you want a hotel-quality mattress without the huge price tag!

Perfect mattress ！ Last month, I was still hesitating which mattress I needed to buy to best meet my expectations. Now, I am lying on this perfect mattress and I am amazed at how comfortable it is. It is really suitable for people with back pain like us. It has two sides to sleep on, one side is soft and the other side is hard, which is in line with the best hardness for both adults and children. In just a few seconds, I purchased queen size. The size is completely suitable for me. Its surface feels very comfortable to the touch and it has excellent cashmere texture, I don't feel any discomfort with the built-in conversation at all. It's really perfect, and I wouldn't hesitate to buy it again for my parents.

Just buy it! First off, this was my first time buying myself a new mattress. All of mine throughout the years have been handed down from other family members getting new ones. So, I took the risk and bought this one because of the positive reviews. The quality is amazing, good material and good layering. It was actually VERY easy to setup, expansion only took about 3-4 hours MAX. Slept on it same day! It is firm, but once you lay on it, it’s not an uncomfortable firm, it’s actually very nice. Overall functionality 10/10!

The mattress arrived faster than I expected. Delivery went smoothly. As soon as I opened it, it immediately took shape. I let it sit for a few hours, but I slept on it that night, and it was incredible. I didn't notice any strong odor when I opened it. From the first night, I noticed an immediate improvement in my back pain. I've had this mattress for a couple weeks now. The constant back pain I used to have is completely gone. Although it's firm, it's not uncomfortable. Unlike my old mattress, I can effortlessly change positions throughout the night. This is a huge plus for restless sleepers like me. I really like this mattress; I sleep much better now, and that's all that matters.

I god the king size 14” . It’s very heavy so to place it by one person it’s not the easiest thing to do but still possible. It fit great to the frame i got and doesn’t move at all!! It’s very comfortable feels like a hotel bed and I waited almost 4 months to write the review to make sure its stay like that and it actually did!! I was surprised because usually with other matterses after 1-2 months it starts to get loose and drop . I sleep on the same side of the bed and it looks and feels like the first night! The very edges aren’t as strong as the center but for me it’s not something bad because its very minor the difference. It’s super quiet, no noise while moving at all . And the best part is that when my partner moves or gets up I don’t feel the movement. Very comfortable
