About This Product

Designed for hot sleepers and couples who can't agree on a thermostat setting, the SweetNight CoolNest® Pro Memory Foam Mattress pairs an advanced four-stage cooling system with a contoured 7-zone support layer to keep you cooler from the moment you lie down through the early-morning hours. More than half of U.S. adults say they sleep hot, and overheating is one of the top reasons Americans wake up during the night. This upgraded model from SweetNight's best-selling CoolNest® series is engineered to address that—managing temperature across four stages of the night so you can sleep deeper and wake up refreshed

Features

4-Stage Cooling System – Ice Silk cover (Qmax 0.23) delivers instant cool-to-the-touch feel; PCMflux® foam with phase-change material absorbs body heat; gel-infused memory foam with 700+ ventilation holes carries heat away; perforated 3D airflow core exhausts warm air throughout the night
7-Zone Ergonomic Support – Contour-Cut precision peak-and-valley structure provides firmer support under hips and lower back, softer cushioning under shoulders and legs for better spinal alignment and pressure relief
Full-Depth Ventilation – 3 perforated airflow layers with 700+ precision ventilation holes allow air to move efficiently across each layer, working with the wave-cut 7-zone base to disperse excess heat from below
Motion Isolation – Multiple adaptive foam layers absorb movement and reduce motion transfer, minimizing sleep disruptions from partner movement
Easy Setup – Ships compressed in a box; expands to full size within 72 hours; fits most bed frames, box springs, slatted bases, and adjustable bases
