SweetNight has introduced the CoolNest® mattress, a foam mattress based on cooling materials and zoned support. Temperature regulation and pressure relief remain top priorities for many mattress buyers, especially those who carefully compare construction details before purchasing. SweetNight is positioning the CoolNest® as a sub-$1,000 option aimed at sleepers looking for cooling-focused features paired with ergonomic support.
A layered approach to cooling
Some foam mattresses can retain heat, especially when air circulation is restricted. The CoolNest® features a multi-layer construction that promotes breathability and helps regulate temperature throughout the night.
On the surface of the mattress there is a 3D knitted cooling cover with micro-ventilation pores designed to increase air circulation. Under the cover is SweetNight’s PCMflux® phase change foam, which contains phase change materials (PCM). According to SweetNight, these materials are designed to absorb and gradually release excess heat, ensuring more consistent temperature conditions over time.
The mattress also contains a gel-infused memory foam layer. According to SweetNight, this layer is designed to help dissipate heat while maintaining the contouring feel associated with memory foam. Together, these components form the basis for the CoolNest®’s cooling-focused design.
Zoned support for alignment and comfort
Cooling is just one element of overall sleep comfort. The CoolNest® also features what SweetNight calls 5-Zone Ergo Support, a zone structure designed to provide targeted support to different areas of the body.
This approach is designed to help minimize pressure buildup and promote spinal alignment, with dedicated zones supporting areas such as the shoulders, hips, and lower back. By combining zonal support with cooling-focused materials, the CoolNest® is positioned as a foam mattress that meets multiple comfort priorities simultaneously.
Prices and target group
Cooling materials and ergonomic design elements are often associated with higher-priced mattresses. With the CoolNest®, SweetNight is targeting buyers who are looking for these features without going into premium pricing tiers. The mattress is listed under $1,000, with the final price varying depending on size and configuration.
Cooling-focused designs can be particularly relevant for people exposed to nighttime temperature fluctuations. SweetNight highlights groups commonly affected by temperature-related sleep disorders, including women and older adults, people taking certain medications, those with metabolic or weight-related heat sensitivity, and people living in warmer climates.
Availability and purchase details
The CoolNest® mattress is available through SweetNight’s direct-to-consumer model. Purchase includes a 100-night trial, free nationwide shipping, mattress delivered in a box, and a 10-year warranty.
The CoolNest® was designed to address two common mattress considerations: temperature management and ergonomic support.
