Features
- 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 airworking 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 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.
- Queen Mattress in a Box: No Assembly, No Heavy Lifting. The queen 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 am honestly blown away by the NAPSIE 12-inch Memory Foam Mattress. From the moment I opened the box, I could tell this was going to be a high-quality mattress. It expanded quickly, had zero chemical smell, and felt incredibly plush right away. Sleeping on it has been a dream—literally. The memory foam contours perfectly to my body without feeling too soft, and I wake up with no pressure-point pain. The cooling feature is real too; I don’t overheat at night anymore, which has always been a problem for me with other foam mattresses. The medium-plush feel is the perfect balance of comfort and support. I fall asleep faster and stay asleep longer. It’s honestly such a noticeable upgrade from my previous mattress. The fact that it’s CertiPUR-US certified just adds even more peace of mind. For the quality, comfort, and price, this mattress is absolutely worth it. I’d recommend it to anyone looking for a supportive and cool night’s sleep.

I’ve been using the NAPSIE 14 Inch Queen Memory Foam Mattress for a while now, and it has exceeded my expectations in every way. Right out of the box, it expanded quickly and had very little odor, which was a big plus. The medium plush feel is just perfect—not too firm and not too soft. It provides great support for my back, and I’ve noticed a real improvement in back and pressure-point pain since switching to this mattress. It contours nicely to the body while still keeping the spine aligned. One of my favorite features is the cooling Tencel cover. I tend to sleep warm, and this mattress truly helps regulate temperature. I wake up feeling comfortable, not overheated or sweaty. The fact that it’s CertiPUR-US certified and made with foam manufactured in the USA gives me peace of mind about quality and safety. For a mattress-in-a-box, the overall build feels very high-end and durable. ✔️ Great back support ✔️ Cool and breathable cover ✔️ Medium plush comfort ✔️ Easy setup ✔️ Excellent value for the price If you’re looking for a comfortable, cooling mattress that supports your back and delivers premium quality without the premium price, this one is a fantastic choice. I would absolutely buy it again and highly recommend it to anyone in need of better sleep.

We bought this full-size memory foam mattress for my kid and it’s been great so far. It was easy to set up and fully expanded pretty fast. It’s comfortable but still supportive, not too soft, not too firm. My kid sleeps really well on it and doesn’t wake up complaining about being uncomfortable. No strong smell either, which I appreciated. For the price, the quality is better than expected and it feels sturdy and well made. Overall, really happy with this purchase.

I was honestly surprised how comfortable this mattress is. The texture feels very dense and well made, not cheap at all. It’s soft and cozy when you lay down, but at the same time it really supports my whole body weight. I don’t sink too much and my back feels relaxed in the morning. It gives a balanced feeling between softness and support. I’ve been sleeping much better since I changed to this mattress. Very happy with this purchase!

Very comfortable to sleep on it. However, the edges are too soft. I'm used to a very firm mattress.

I am absolutely thrilled with my new 12-inch Full mattress! As someone who sleeps hot but needs pressure relief for my shoulders and hips, this mattress is a dream come true. The combination of the TENCEL cover and the cooling gel-infused memory foam actually works—I no longer wake up feeling overheated. The 'medium plush' feel is perfectly described; it's firm enough to support my back without any sinkhole feeling, yet soft enough to relax and cradle my body. The 12-inch profile gives it a substantial, quality feel. The fact that it arrived in a box, handled easily, and expanded quickly was just the icing on the cake. Highly recommend for anyone seeking a cool, comfortable, and supportive sleep experience!

I have not had much luck with these types of mattresses in King size. But I decided to give this one more try since I had a friend who recommended this brand. I had much success in all of the other sizes but for some reason king size have never worked for me. But this one is finally a good one! This one does not sink in the middle like all of the others have. This one is 30 and firm yet soft at the same time. It has just a support I need. The edges aren't so soft that it falls in like my last one. This one has good sturdy edges. Highly recommend for an affordable roll out bed. This puffed up and we let it out on my living room for 3 days. It probably would have been fine before that but I wanted to be sure. It was instantly comfy.
