Napsie TriCool Matrix: Our TriCool Tech combines a breathable TENCEL cover, cooling gel foam, and charcoal-infused egg crate foam. This advanced matrix actively wicks heat, regulates temperature, and increases airflow for all-night comfort, ideal for aching backs and hot sleepers.
More Breathability: TENCEL fibers move moisture better than common fabrics, while the egg crate structure creates dedicated 3D airflow channels that actively circulate air—working together to prevent heat buildup and sweat accumulation for scientifically cooler sleep.
Enhanced Pressure-Relief: The contoured surface of egg crate foam cradles high-pressure areas like shoulders and hips more effectively than flat foam, paired with the spinal alignment maintained by the BraceSleeper Support Foam, reducing pressure points for sore backs.
Eco-conscious and Certified Safe: This mattress features TENCEL fibers and natural bamboo characoal, known for their Plant-based properties. CertiPUR-US Certified foam provids a Child-Safe & Chemical-Free sleeping environment especially for the health-conscious sleepers.
Full Mattress in a Box: No Assembly, No Heavy Lifting. The full size mattress is rolled, compressed and delivered straight to your door in a compact box for shipping. It is also compatible with most bed bases and frames.

I'm really happy with this mattress! It popped up quickly once I unboxed it and didn't have much of a smell at all. The medium plushness is just right — comfy enough for a good night's sleep but still offers good support for my back. I've been feeling a lot less pressure on my shoulders and hips too. Plus, it sleeps cooler compared to my old memory foam mattress, which is a huge bonus. The quality seems great, and the fact that it's CertiPUR-US certified makes me feel even better about my purchase. Such a good deal for the price — I'm sleeping way better now!

Best Sleep I’ve Had in Years
I’m really impressed with the NAPSIE 12-inch Memory Foam Mattress. As soon as I took it out of the box, I could tell it was made well. It expanded quickly, had no unpleasant smells, and felt plush from the start. Sleeping on it has been —literally. The memory foam fits my body just right without being too soft, and I wake up without any pressure-point discomfort. The cooling feature works great too; I don’t wake up hot anymore, which has been an issue with other foam mattresses I’ve tried. The medium-plush feeling strikes the right balance between comfort and support, helping me fall asleep faster and stay asleep longer. It’s a huge upgrade from my last mattress. Plus, knowing it’s CertiPUR-US certified gives me extra reassurance. For the quality and comfort, this mattress is worth it. I’d recommend it to anyone wanting a supportive and cool sleep experience.
