10 Best Sweetnight Mattress 2025 in the United States

The Sweetnight CoolNest 14 Inch King Size Mattress presents a compelling option for those seeking a cool and supportive sleep surface. Its standout feature is the dual cooling technology, combining PCMflux high-resilience foam with gel-infused memory foam, which is especially beneficial for hot sleepers, as it promises up to 8 degrees cooler sleep temperatures. The mattress is rated as medium firm, which can be ideal for individuals desiring a balance between support and plushness.

Support is a key strength of this mattress, with a five-zone system designed to relieve pressure and promote proper spinal alignment. This can be particularly appealing for those who suffer from back pain, and its endorsement by the American Chiropractic Association adds credibility. It’s also efficient in isolating motion, meaning that movement from a partner won’t disturb your sleep.

In terms of breathability, the mattress excels with its 3D woven cover and hollow-structured foam, which optimizes airflow and wick moisture, potentially enhancing comfort throughout the night. However, at 90.1 pounds, this mattress could be cumbersome to move and set up, though it does come compressed in a box for seemingly easier handling. One potential drawback could be its lack of options in firmness levels, as only a medium firm is available. Additionally, while the mattress is CertiPUR-US certified, ensuring no harmful chemicals, the long-term durability remains to be tested despite a 10-year warranty.

Best suited for those who prioritize temperature regulation and pressure relief, the Sweetnight CoolNest mattress holds promise for a comfortable and cool night's sleep, but those preferring a softer or firmer feel might need to consider other options.

The Sweetnight 12” Hybrid King Mattress combines gel memory foam with pocket innerspring coils, offering a balanced medium-firm feel. This hybrid design ensures body contouring and provides good support, making it a suitable option for those with back pain due to its ability to keep the spine aligned. The mattress also excels in edge support, thanks to an added layer of foam which is beneficial for individuals who prefer sleeping near the edge of the bed.

Another strong point is its temperature regulation; the gel memory foam and moisture-wicking cover help maintain a cool sleeping environment, which can be crucial for those who tend to overheat at night. Motion isolation is also a highlight, as the individually wrapped coils minimize disturbance from a partner’s movements. Durability is another strength, backed by a 10-year warranty, ensuring long-term use.

However, the mattress is relatively heavy at 115.3 pounds, which might make it cumbersome to set up or move. This mattress is well-suited for those seeking balanced support, good motion isolation, and temperature control, especially if they sleep hot or have back pain.

The Sweetnight CoolNest Queen Mattress is a 14-inch memory foam mattress designed for a cool, comfortable sleep. One of its main strengths is the CoolNest System, which uses both PCMflux high-resilience foam and gel-infused memory foam to keep sleepers cool by actively regulating temperature and reducing overheating. This is particularly beneficial for hot sleepers who struggle with night sweats.

The 5-Zone Ergo Support system offers targeted pressure relief and promotes proper spinal alignment, which can help alleviate back pain—a feature endorsed by the American Chiropractic Association. The mattress also excels in motion isolation, making it a good choice for couples since it minimizes disturbances caused by movement. The enhanced breathability feature, thanks to its 3D-woven cover and high-resilience foam, ensures a cooler and drier sleep environment. Additionally, the CertiPUR-US and OEKO-TEX certifications point to a safer and healthier sleep experience.

However, the mattress is rated as medium firm, which may not suit those who prefer a very soft or very firm sleeping surface. The edge support is not specifically mentioned, so it might be less robust compared to other high-end options. While the mattress offers a 10-year warranty and comes conveniently compressed in a box, it's essential to allow it 72 hours to fully expand before use. Weighing 61.7 pounds, it may require some effort to set up. Ideal for those seeking a cool, supportive, and motion-isolated sleep experience, this mattress strikes a balance between comfort and functionality.
