Sleep cooler for less: SweetNight's CoolNest Ultra gets early Black Friday pricing

Nov 3, 2026 — 10:18 AM ET

If you’ve ever kicked off your covers in the middle of the night to cool down, you know how heat can ruin your sleep. Traditional memory foam is comfortable, but it often traps body heat.

SweetNight’s new CoolNest Ultra Memory Foam Mattress delivers the perfect mix of cool and comfortable, combining a 5-stage cooling system with 7-zone support. With the brand’s Black Friday Early Access sale already live, now is a great time to invest in a perfect night’s sleep. Here’s what you need to know.

Five stages of cooling

The Gradient Cooling Ice Silk Cover feels cool when you touch it, with a Qmax rating of 0.25 — 47% higher than standard cooling fabrics. Over 10,000 micro-pores per square centimeter let heat and moisture escape.

Underneath, a layer of PCMflux High Resilience Foam uses phase change material (PCM) and gel particles to absorb, store, and release heat throughout the night. Next, AirMesh Breathable Memory Foam has a hollow mesh structure that’s up to six times more breathable than regular closed-cell memory foam. And a Ventilated Gel Memory Foam layer, with 30% gel and over 700 vents, also helps pull heat away.

Perforations in the CoolNest Ultra’s upper layers and the airflow channels in the wave-shaped support foam work together to create a 3D ventilation system. This helps move heat and moisture out of the mattress, so you can sleep up to 11° cooler.

Seven zones of support underneath

Below the cooling layers, a 7-zone Ergonomic Support Foam layer with a wavy-cut design gives targeted support to your head, shoulders, back, waist, hips, legs, and feet. It keeps your spine aligned and spreads out pressure for a more comfortable sleep.

The Enhanced Stability Support Foam base helps reduce sagging over time, while the anti-slip dotted fabric bottom keeps the mattress in place.

The CoolNest Ultra comes in Queen and King sizes, with options for 12, 14, or 16-inch thickness. The 12-inch model feels medium, while the 14- and 16-inch versions are medium-plush. The fabric is OEKO-TEX certified, the foams are CertiPUR-US certified, and the mattress contains no fiberglass. The American Chiropractic Association endorses the CoolNest Ultra, and it meets International Sleep Products Association (ISPA) standards.
