$469.99
Product Overview
The Sweetnight CoolNest Queen Mattress offers a thoughtfully engineered solution for restful, temperature-regulated sleep. Designed with both comfort and performance in mind, this 14-inch queen mattress integrates the proprietary CoolNest System—a dual-layer cooling technology that actively manages body heat throughout the night. Ideal for hot sleepers, couples sensitive to motion transfer, or anyone seeking balanced support and pressure relief, the mattress delivers medium firmness with responsive contouring. Every component is CertiPUR-US certified, ensuring safety, durability, and freedom from harmful chemicals. Whether you’re upgrading your bedroom or furnishing a guest space, the CoolNest provides a modern foundation for deeper, more comfortable rest.
Key Features
- CoolNest System Technology: At the heart of this mattress is the innovative CoolNest System, which combines PCMflux high-resilience foam with gel-infused memory foam in a dual-layer configuration. This design enhances airflow while actively dissipating heat away from the sleeper. Unlike traditional foams that trap warmth, the CoolNest System maintains a cooler microclimate close to the body, helping prevent nighttime overheating and promoting longer periods of uninterrupted sleep.
- 5-Zone Ergo Support: The mattress features five distinct ergonomic zones tailored to different parts of the body. These zones provide targeted support to the head, shoulders, back, hips, and legs, aligning the spine naturally and reducing pressure points. By distributing weight more evenly, the system minimizes discomfort associated with side or back sleeping and reduces motion transfer between partners.
- Medium Firmness Profile: With a balanced feel, the CoolNest Queen strikes a middle ground between plush softness and structural firmness. This makes it suitable for a wide range of sleep styles—back, side, and combination sleepers alike can find adequate cushioning without compromising spinal alignment. The medium profile also supports lighter to average-weight individuals without bottoming out.
- CertiPUR-US Certified Materials: All foam layers meet rigorous testing standards set by CertiPUR-US, an independent organization focused on product safety and transparency. Certification confirms low emissions (VOCs), absence of ozone depleters, phthalates, and heavy metals, as well as formaldehyde and PBDE flame retardants. This gives buyers peace of mind regarding indoor air quality and long-term health considerations.

Benefits & Use Cases
One of the most common causes of restless nights is excess body heat trapped under standard mattresses. The Sweetnight CoolNest addresses this with its active cooling architecture, making it especially beneficial for people who run warm, exercise regularly before bed, or live in warmer climates. The gel-infused memory foam draws heat away from the surface while the open-cell structure of PCMflux foam encourages continuous air circulation. Together, they create a breathable environment that stays cool even during prolonged use.
In addition to temperature control, the 5-zone support system adapts dynamically to your body’s shape and movement. Side sleepers benefit from shoulder and hip relief, while back and stomach sleepers gain stability and reduced lower back strain. The medium firmness ensures the mattress contours gently without creating sinkage that could misalign the spine. Because it limits motion transfer, couples sharing the bed won’t be disturbed by their partner’s movements—making it a solid choice for light sleepers or those with different preferred sleep positions.
This mattress is also designed with practicality in mind. Its rolled and compressed packaging allows for easy delivery into apartments, condos, or multi-story homes without requiring large furniture movers. Upon unboxing, it expands within 24 to 72 hours to full size, though immediate light use is possible once the initial expansion phase completes. For optimal longevity and hygiene, pairing the mattress with a breathable protector is recommended.
Suitable for primary bedrooms, guest rooms, or temporary accommodations like vacation rentals, the CoolNest Queen blends performance, safety, and everyday usability. It avoids extreme softness or rigidity, instead offering a universal appeal that adapts comfortably to various body types and sleeping habits.
Important Notes
Upon delivery, carefully remove the outer protective wrap and allow the mattress to expand fully before regular use. Initial off-gassing—a natural release of minimal volatile organic compounds during unpacking—typically diminishes within a few days. Do not attempt to re-roll or compress the mattress after it has expanded; doing so may damage internal layers. Placing the mattress directly on a non-breathable surface such as carpeted frames or plastic sheets can impede airflow and reduce cooling efficiency. Always use a supportive, ventilated foundation like a box spring or platform bed frame. Please review the manufacturer’s warranty terms and return policy at time of purchase, as coverage may vary depending on retailer or region.

great mattress and comfortable
I was honestly a little nervous ordering a mattress online, but this one completely surprised me. It expanded quickly and had very little smell. The 14-inch thickness feels substantial, and it fits perfectly on my metal bed frame.I love the balance of support and comfort — it’s not too soft, not too firm. I usually wake up with lower back tension, but since switching to this mattress, I’ve been sleeping much deeper and waking up without stiffness. The cooling top actually makes a difference too; it doesn’t trap heat like my old memory foam did.For the price, the quality is impressive. It looks clean and modern in my bedroom and feels like a much more expensive mattress. Definitely a great buy!

Luxury-Level Comfort, Night After Night
I hate when people say “for the price, it’s a great mattress.” You could charge $2,500 for this mattress and it would still be worth every dollar. It’s that comfortable. It feels genuinely luxurious the moment you lay down. My sleep quality improved immediately, and I wake up feeling rested instead of overheated. This mattress sleeps incredibly cool—like, noticeably cool to the touch.Honestly, if you’re reading this review, your mattress search is over. Pair it with bamboo sheets and you’ll feel like you’re waking up in a Four Seasons suite every morning. Comfortable, supportive, and impressively cool—this mattress delivers on everything.

Nice upgrade from my old mattress
It was easy to set up and expanded pretty quickly after opening. The queen size fits my bed frame well.The mattress feels comfortable overall, with a nice balance between softness and support. It’s soft enough to feel relaxing when lying down, but still firm enough that I don’t feel like I’m sinking in too much. I’ve been sleeping on my side and back without any discomfort.I also like the height and how it looks once the bed is made. It gives the bed a cleaner and more finished look compared to my old mattress. So far it has been a good upgrade for everyday sleep.For the price, I think it’s a solid option and feels worth it.

Maybe the matress tranfer me from springbox to memory foam
I’ve always preferred firm spring mattresses and honestly didn’t think memory foam would be for me. I had this idea that it would feel too soft, sink too much, or sleep hot. I bought the Cooling King Memory Foam Mattress mainly to give it a try, and after using it for a month, I’ve completely changed my mind. The first few nights took a little getting used to because the foam contours to your body differently than a traditional spring mattress. But after about a week, I started noticing that I was waking up feeling more relaxed. I used to have some neck and lower back stiffness in the mornings, and that’s pretty much gone now. The support is much better than I expected—it feels soft on top but still supportive underneath.One thing I didn’t expect was how evenly it distributes weight across the surface. Instead of feeling pressure in specific areas like my shoulders or hips, it feels more balanced and cushioned without losing that firm base I like. I also noticed that I don’t toss and turn as much during the night, probably because my body feels more supported in a natural position. Even when I switch sleeping positions, the mattress adjusts quickly without feeling like I’m stuck or sinking too deep. That combination of comfort and stability has made a noticeable difference in the overall quality of my sleep.I was also worried about heat retention, but so far it hasn’t felt overly warm or stuffy at night. It’s actually been quite comfortable temperature-wise. Overall, I’m genuinely surprised at how much I like it. If you’ve always been a firm spring mattress person like me and are hesitant about memory foam, it might be worth trying. It definitely changed my opinion.
