As a non-profit sleep research leader with 10+ years of experience, Sleep Foundation'"Best Cooling Mattress" selection is renowned for strict neutrality no brand sponsorships, no paid placements, and a specialized cooling test protocol that includes thermal imaging, 72-hour heat retention tracking, and real hot sleepers' 2-week field trials. The SweetNight CoolNest's win isn't just a title; it's proof of passing rigorous, data-driven scrutiny for temperature regulation a rare feat for an affordable foam mattress.

 

Certification Endorsement

 

Sleep Foundation explicitly named the CoolNest its "Best Cooling Mattress" for 2025, praising it for "sleeping considerably cooler than the average memory foam model" and effectively addressing the biggest pain point of foam mattress users: heat retention.

 

Cooling Technology Breakdown

The SweetNight CoolNest is engineered with a multi-layered approach to ensure superior temperature regulation, drawing directly from advanced material science:
 
  • 3D Breathable Woven Cover: Features 10,000+ micro vents designed to boost air circulation by 35%, actively preventing heat buildup on the mattress surface.
  • PCM Phase-Change Foam: Infused with specialized temperature-regulating particles that intelligently absorb excess body heat when you're hot and release it when you're cool, maintaining an optimal sleep temperature.
  • Gel-Infused Memory Foam: This innovative layer draws heat away from pressure points, counteracting the common "stuffy" feel associated with traditional memory foam.
 
Open-Cell Foam Structure: The internal construction of the foam layers is designed with an open-cell structure, significantly enhancing internal airflow to reduce heat trapping within the mattress core.
SweetNight CoolNest mattress layers: CoolNest Cover, PCMflux, Gel-infused & Ocean memory foam, comfort foam, zoned support.
