10 Best Sweetnight Mattress 2025 in the United States

The Sweetnight 16 Inch Queen Size Mattress offers a medium firmness level that suits those who prefer balanced support—not too soft or too hard. Its standout feature is the 5-zone ergo support system, designed to provide targeted pressure relief from head to toe and help maintain proper spinal alignment, which is great if you experience back discomfort. This mattress uses gel-infused memory foam combined with high-resilience foam to create a cooling effect, thanks to an innovative CoolNest system. This helps keep you comfortable throughout the night by reducing overheating, ideal for people who tend to sleep hot. Motion isolation is strong due to multiple foam layers, so if you share your bed, you’re less likely to be disturbed by your partner’s movements. Breathability is also enhanced with a special 3D-woven cover and foam structure that promotes airflow and moisture-wicking, adding to the overall comfort.

Edge support isn’t specifically highlighted but the firmness and foam density suggest reasonable stability when sitting or sleeping near the mattress edges. The mattress is CertiPUR-US and OEKO-TEX certified, ensuring it’s made with safe, non-toxic materials, and it comes compressed in a box for easy setup with a 10-year warranty for durability. As a full memory foam mattress, it may retain some heat more than hybrid options and might feel a bit firm for those who like a very soft surface. It also requires up to 72 hours to fully expand after unboxing. For those seeking a comfortable, supportive mattress that stays cool and reduces motion transfer, this Sweetnight mattress is a reliable option, especially for back sleepers or individuals needing pressure relief.

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.

The Sweetnight Tri Folding Mattress is a 4-inch thick, medium-firm mattress designed for portability and convenience. Its tri-fold design with a zipper allows it to be separated into three smaller mats, making it flexible for different spaces like RVs, camping spots, or guest rooms. It’s made from dual-layer polyurethane foam, combining a softer top layer with a firmer base to offer balanced comfort and support. This design makes it comfortable enough for short-term use, though it may not provide sufficient cushioning or spinal support for everyday sleeping.

The mattress includes CertiPUR-US certification and features a breathable knitted cover that enhances air circulation to help keep you cooler throughout the night. While it is not water-resistant, the foam layers provide effective motion isolation, reducing movement transfer if you share the mattress. Due to its thinner design and foldable nature, edge support is limited, which may cause sitting or sleeping near the edge to feel less stable compared to traditional mattresses.

Lightweight and equipped with handles for easy transport, the mattress also has a removable and washable cover for convenient cleaning. Durability is suitable for occasional use, but the 4-inch thickness could lead to quicker wear with heavy or long-term use. This mattress is ideal for those who need a portable, easy-to-store option for guests or travel rather than a permanent, high-performance sleeping solution.
