Still tossing and turning through sweaty nights? You’re not alone — overheating is one of the top reasons people can’t stay asleep. The new SweetNight CoolNest™ Mattress solves this with breakthrough cooling technology that keeps you up to 8 degrees cooler. It also provides five-zone ergonomic support for healthier rest. And at just $500, CoolNest brings luxury-level comfort to more households than ever before.
Cooling System: The Best Cooling Mattress of 2025
Unlike traditional mattresses that trap heat, the CoolNest is built with the CoolNest System — a multi-layer approach to cooling that works from the surface down:
- 3D-knitted cooling cover: With thousands of tiny ventilation pores, airflow is boosted by 35%, keeping the mattress fresh and breathable all night. In simple terms, it’s a soft, airy cover that helps heat escape, so you don’t wake up sweaty.
- PCMflux™ high-resilience foam: Infused with phase-change materials (PCM), this smart foam adapts in real time to your body temperature. It absorbs heat when you’re warm and releases it when you’re cool, keeping you balanced for up to 8 hours.
- Gel-infused memory foam: With 30% more cooling gel, evenly distributed for maximum efficiency, this layer cushions pressure points while drawing heat away — offering both comfort and coolness at once.
Together, these layers create a refreshing, cool-to-the-touch surface with 3× better airflow than conventional foams
5-Zone Ergo Design: An Ergonomic Mattress for Back Pain
CoolNest isn’t just about cooling — the CoolNest also is certified by the American Chiropractic Association. The group says it focuses on “products that are of the highest quality and have a chiropractic-related benefit for consumers and doctors of chiropractic.”
The 5-Zone Ergo Support system targets key areas of the body:
- Shoulders and legs – Gentle cushioning
- Lumbar region – Firm support to maintain spinal alignment
- Hips – Adaptive contouring to prevent sinking
- Full body – Balanced relief from head to feet
The result? Less back pain, improved posture, and deeper, restorative sleep. It’s not just a cooling mattress — it’s also one of the best ergonomic mattresses for back pain relief.
Who It’s For
CoolNest is built for:
- Hot sleepers who struggle with night sweats
- Back and side sleepers needing full-body support
- Back pain sufferers seeking pressure relief
- Couples who want motion isolation for undisturbed rest
- Budget-conscious families looking for premium sleep at an honest price
