Colchón de Espuma Viscoelástica CoolNest®

The SweetNight CoolNest® Memory Foam Mattress is the best cooling mattress for hot sleepers, with independent testing proving it sleeps 8 degrees Celsius cooler than traditional memory foam. The triple-layer CoolNest® System (10,000+ micro-vents + PCM technology + gel foam) provides all-night temperature regulation. At $499 for Queen, it's also the best cooling mattress under $500.

The Pro cools layer by layer:

(1) the gradient ice-silk cover (Qmax 0.23, 10,000+ micro-pores/cm²) feels instantly cool and adds 35% more cooling power than standard cooling fabrics;

(2) PCMflux® high-resilience foam absorbs excess heat and boosts airflow up to 3×;

(3) perforated comfort memory foam ventilates while contouring to the body;

(4) a perforated gel-infused layer (30% gel + 700+ ventilation holes) actively pulls heat away. Full-depth ventilation then channels heat out for faster heat release and cooler, all-night comfort.

Yes. The Pro is ACA-endorsed and built for spinal alignment with upgraded 7-zone precision support and reinforced edge support. The seven contour-cut zones deliver targeted, full-body relief from head to toe.

Yes. The CoolNest® Mattress is designed with couples in mind:

(1) High motion isolation helps minimize partner movement disturbance.

(2) Advanced cooling technology reduces heat buildup.

(3) 5-zone support adapts to different body types;

(4) A queen-size provides approximately 30 inches of space per person, while a king offers about 38 inches each.

It’s rated 4.8 out of 5 stars by customers.

Medium — the same balanced, crowd-pleasing feel as the standard CoolNest®: enough pressure relief for side sleepers and enough support for back sleepers, with upgraded 7-zone contouring for full-body relief.

The Pro is the upgraded version. Compared with the standard CoolNest®, it steps up from triple-stage to four-stage cooling, swaps the 3D-knit cover (Qmax 0.22) for a gradient ice-silk cover (Qmax 0.23) that feels cooler to the touch, adds full-depth ventilation for faster heat release, and upgrades 5-zone support to 7-zone precision support. Choose the standard CoolNest® for budget-friendly essential cooling; choose the Pro for stronger, longer-lasting cooling and enhanced comfort.

Yes. The all-foam design absorbs movement for strong motion isolation, advanced four-stage cooling keeps both partners comfortable, and 7-zone precision support adapts to different body types. A Queen gives roughly 30" per person and a King about 38" each.

Yes. Sleep on the CoolNest® Pro for 100 nights; if you're not satisfied, contact us for free pickup and a full refund (we recommend at least 30 nights to adjust). Returned mattresses are donated to local charities. Includes a 10-year warranty covering sagging over 1.5 inches.

Three: (1) CertiPUR-US® — all foams free from harmful chemicals, ozone depleters, and heavy metals; (2) OEKO-TEX® STANDARD 100 — the ice-silk cover is tested for skin safety; (3) ACA-endorsed — its 7-zone precision support is recognized by the American Chiropractic Association.

• Those who experience night sweats (moisture-wicking design)

• Allergy-conscious sleepers (CertiPUR-US® certified materials)

Its versatile design makes it a strong choice in the cooling mattress category.

The Pro delivers four-stage advanced cooling, a cool-touch ice-silk cover, and 7-zone precision support — features comparable to premium cooling beds that often cost several times more — starting at $529.99, with a 10-year warranty, 100-night trial, and ACA endorsement.

Hot sleepers who want stronger, longer-lasting cooling; back- and side-sleepers needing precise 7-zone, full-body support; couples who value motion isolation; those who run hot or sweat at night; and anyone ready to upgrade from a standard cooling mattress for enhanced comfort and breathability.
