Features
- CoolNest System for a Cooler Night - The CoolNest 16-inch queen mattress features our innovative CoolNest System, combining PCM high-resilience foam with gel-infused memory foam for layered cooling comfort. This advanced system helps dissipate heat and maintain a cooler surface throughout the night, creating a cooler and more comfortable sleep environment for hot sleepers.
- 5-Zone Support for Pressure Relief - Engineered with a 5-zone design, this queen size memory foam mattress integrates support foam and comfort foam to help cushion pressure areas from head to toe. It helps redistribute pressure while maintaining stability and balanced support for enhanced comfort. Recognized by the American Chiropractic Association (ACA), it's designed to promote a more restful sleep experience.
- Motion Isolation for Undisturbed Sleep - Constructed with multiple layers of memory foam, the CoolNest 16-inch queen foam mattress helps absorb motion and reduce vibrations. Additionally, these layers work synergistically to minimize motion transfer, so you're less likely to be disturbed whether your partner shifts positions or gets up during the night. Wake up feeling more refreshed.
- Enhanced Breathability for Cooler Comfort - The CoolNest cover incorporates 3D-woven technology, featuring a ventilation pore design that improves breathability by 35% compared to standard fabrics. Also, the PCM high-resilience foam with a hollow structure promotes 3X airflow. Together, these features help to wick away moisture and adapt to body temperature for a cooler, drier sleep surface.
- Restful Sleep & Mattress in a Box Queen Size - The Sweetnight CoolNest gel-infused memory foam mattress features CertiPUR-US certified foams and certified cover, which provides a comfortable sleep environment. The 16-inch queen cooling mattress is compressed in a box for easy setup. Additionally, it comes with a 10-year protection. Please allow the Sweetnight mattress to fully expand for 72 hours.

This Sweetnight mattress has been a total game-changer for my sleep! I’ve always struggled with memory foam mattresses that sleep hot, but the cooling layer on this one works so well — I stay comfortable all night, even in warmer weather. The medium feel is just right: supportive enough for my back and shoulders, but still soft enough to sink into comfortably. The 5-zone support makes a noticeable difference in how my body feels when I wake up, no more stiffness or pressure points. Setup was super easy, and it expanded fully within a day. I also love that it’s CertiPUR-US certified, so I feel good about the quality and safety. If you’re looking for a cooling, supportive mattress at a great price, this one is definitely worth it!

I absolutely love this mattress. I've always been looking for a mattress with a medium firmness, so I've been on a mattress-buying journey. Finally, I've found this mattress that suits me perfectly. It has a detachable fitted sheet and feels cool to the touch, especially when the weather is just right. Although it feels soft when pressed with fingers, you don't notice any softness when sitting or lying down. My mattress is a king size, and it fits perfectly with my bed frame, being just the right size. Its quality is impeccable, and I can finally have a good night's sleep.Thank you!

In a word- Yes. It’s very comfortable- firm yet supple without being hard, while supportive in a slightly form-fitting way. The mattress was delivered within a few days. It’s easy to unbox and set up- the mattress expands very quickly. There was no odor. Be careful opening the shipping box and cutting plastic wrap of mattress. From the first night, I noticed the difference it’s very comfortable, provides great support, and doesn’t sink. The size is perfect,I’ve been sleeping much better since I got it. It doesn’t get hot and adapts very well to the body. if you’re looking for something comfortable, affordable, It also offers great value for the price compared to other mattresses on the market.I definitely recommend this mattress to anyone looking for comfort, quality, and affordability.

We’re a couple and just got this mattress, and it was ready much faster than expected—pretty much fully expanded and usable after about a day, which was a nice surprise. After the first night, we’re already really impressed. The cooling is noticeable right away—it doesn’t trap heat like our old mattress, and we both slept more comfortably without waking up sweaty. The support feels well-balanced too, not too soft or too firm. I usually have some lower back discomfort, and even after one night I could feel a difference—it felt more aligned and less pressure in the morning. It’s also very easy to set up and use. Taking it out of the box was straightforward, and we didn’t have to wait days for it to be ready, which made the whole experience much smoother. Motion isolation works well too. One of us moves a lot during the night, but the other barely notices. Even our cat jumping on and off the bed didn’t really disturb our sleep. Overall, it already feels like a big upgrade after just one night. Comfortable, supportive, cool, and super convenient—very happy with it so far.

I’ve been using the Sweetnight CoolNest 12” King Mattress for a bit now, and overall I’m impressed. The thickness is just right, the medium firmness feels accurate, and it gives excellent support without sagging. I wake up without pressure points, which is a big win. The cooling performance is genuinely good — it stays comfortable through the night. For the price, the value is honestly hard to beat, and delivery was smooth and on time. A couple of drawbacks: the top surface is not quilted, so it feels very flat compared to mattresses with a cushioned top layer. Also, the cover isn’t cotton, so it has a slightly synthetic/artificial feel. Not a dealbreaker, but worth noting. Overall, a great value mattress with solid support and cooling, just not the plushest surface finish.

Really happy with this mattress so far. It’s very comfortable and supportive without being too soft or too firm. I noticed a difference from the first night and have been sleeping much better since getting it. It also stays cool at night and doesn’t sink in like some other mattresses. Delivery was fast, setup was easy, and the mattress expanded quickly after opening. There was no strong smell either, which was a big plus. Overall, the quality feels great for the price, and it’s been a really good value. Definitely recommend if you’re looking for a comfortable and affordable mattress.
