SweetNight has introduced the CoolNest® Mattress, a foam mattress built around cooling-oriented materials and zoned support. Temperature regulation and pressure relief remain top priorities for many mattress shoppers, particularly those who closely compare construction details before purchasing. SweetNight positions 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 airflow is limited. The CoolNest® is built with a multi-layer construction intended to promote breathability and help regulate temperature throughout the night.
At the surface, the mattress features a 3D knitted cooling cover with micro-ventilation pores intended to increase airflow. Beneath the cover is SweetNight’s PCMflux® phase change foam, which incorporates phase-change materials (PCM). SweetNight says these materials are designed to absorb excess warmth and release it gradually, supporting more consistent temperature conditions over time.
The mattress also includes a gel-infused memory foam layer. SweetNight says this layer is intended to help disperse heat while maintaining the contouring feel associated with memory foam. Together, these components form the foundation of the CoolNest®’s cooling-oriented design.

Zoned support for alignment and comfort

Cooling is only one element of overall sleep comfort. The CoolNest® also incorporates what SweetNight refers to as 5-Zone Ergo Support, a zoned structure designed to deliver targeted support across different areas of the body.
This approach is intended to help minimize pressure buildup and promote spinal alignment, with dedicated zones supporting areas such as the shoulders, hips, and lower back. By combining zoned support with cooling-focused materials, the CoolNest® is positioned as a foam mattress designed to address multiple comfort priorities at once.

Pricing and intended audience

Cooling materials and ergonomic design elements are often associated with higher-priced mattresses. With the CoolNest®, SweetNight targets shoppers seeking these features without stepping into premium price tiers. The mattress is listed under $1,000, with final pricing varying by size and configuration.
Cooling-focused designs may be especially relevant for individuals who experience nighttime temperature fluctuations. SweetNight highlights groups commonly affected by temperature-related sleep disruptions, including women and older adults, people taking certain medications, individuals with metabolic or weight-related heat sensitivity, and those living in warmer climates.
