Cooling Mattress

SweetNight mattresses use a multi-layer cooling design to regulate temperature from top to bottom. The Ice Silk Cover
instantly wicks away heat and moisture, the PCMflux® High Resilience Foam adapts to your body temperature, and the Gel-Infused Memory Foam with Dynamic Coil™ promotes airflow while dispersing heat. Combined with a ventilated hybrid structure, this system keeps hot sleepers cool, dry, and comfortable all night.

Yes. Cooling mattresses use materials like phase-change foam, gel infusion, and breathable covers to actively draw heat away from your body. In SweetNight's CoolNest® System, each layer targets a different stage of cooling — from instant surface relief to sustained temperature regulation throughout the night.

Our CoolNest® Hybrid Mattress (starting from $399.99) is widely considered the best choice for hot sleepers, thanks to its multi-layer cooling system and ventilated coil design that keep you comfortable all night. If you prefer a foam-only feel, the CoolNest® Memory Foam Mattress (starting from $329.99) is also engineered to stay cool while providing temperature-regulated support throughout the night.

When choosing a cooling mattress, consider:

• Mattress type: Hybrids with coils improve airflow, while gel-infused or latex foams offer breathability for foam-only sleepers.
• Mattress cover: Breathable, moisture-wicking covers like cotton, silk, or ice silk help keep your body temperature stable.
• Bedding: Use breathable sheets and protectors that allow airflow to maximize cooling.
• Other factors: Room temperature, health conditions like menopause or acid reflux, and lifestyle can impact how hot you sleep.

Some cooling mattresses may lose performance as lower-quality foams compress, but SweetNight’s CoolNest® mattresses are made with high-resilience PCMflux® foam and ventilated layers to maintain cooling and comfort. They are backed by a 10-year limited warranty against sagging and defects, giving hot sleepers long-term confidence in temperature regulation.

SweetNight offers multiple flexible payment options: Affirm, PayPal, Truemed (FSA/HSA). Eligible products, including mattresses and cooling pillows, can be purchased with HSA/FSA funds following our FSA/HSA guide.

For hot sleepers, yes — a cooling mattress can significantly improve sleep quality by preventing night sweats and restless tossing from heat buildup. SweetNight's cooling mattresses start at $329.99 with free shipping and a 100-night risk-free trial, making it easy to test whether cooling technology works for you.

Cooling mattresses are designed with breathable, temperature-regulating materials that actively reduce heat buildup, while regular mattresses may trap warmth. SweetNight mattresses combine multi-layer cooling, ventilated coil support, and adaptive foams to keep hot sleepers comfortable throughout the night.
