SweetNight Unveils CoolNest® Ultra Cooling Memory Foam Mattress for Hot Sleepers and Expands Its Cooling Sleep Portfolio

WILMINGTON, Del., Aug. 21, 2026 /PRNewswire/ -- SweetNight, a sleep brand focused on accessible premium comfort solutions, today announced the official U.S. launch of the CoolNest® Ultra Memory Foam Mattress, alongside two new cooling bedding products: the CoolNest® Cooling Comforter and CoolNest® Ergonomic Cooling Pillow. The launch marks the next step in SweetNight's evolution beyond its mattress-focused roots, expanding its cooling sleep portfolio across the broader sleep environment to address the interconnected needs of cooling, comfort, and support. By bringing advanced cooling technologies to both mattresses and bedding, SweetNight aims to create a more comprehensive cooling sleep experience for hot sleepers.

CoolNest® Ultra Memory Foam Mattress: Advanced Cooling Meets Advanced Support

As the latest addition to the CoolNest® Series, the CoolNest® Ultra Memory Foam Mattress is built around two core pillars: advanced cooling and advanced support. The all-foam design combines SweetNight's latest cooling and ergonomic technologies to address common hot-sleeper concerns around overheating and support.

The new mattress features SweetNight's upgraded 5-Stage Cooling System, designed to help manage nighttime heat and night sweats while promoting continuous airflow throughout the mattress. The system combines a cooling Ice Silk Cover with temperature-balancing PCMflux® High-Resilience Foam, AirMesh™ Breathable Memory Foam, and ventilated gel memory foam to support heat dissipation and airflow. A 3D airflow structure further enhances ventilation within the mattress, helping create a cooler, fresher, and more breathable sleep environment throughout the night.

Beyond temperature management, the CoolNest® Ultra delivers enhanced support through a Refined 7-Zone Support System that targets key pressure points of the body. Its ergonomic design is intended to promote natural spinal alignment and more even weight distribution, while a high-density support base provides added stability for lasting comfort.

"CoolNest® Ultra marks another step in SweetNight's commitment to advancing the cooling mattress experience for hot sleepers," said Amber ZHU, Marketing Director at SweetNight. "We're focused on creating thoughtful sleep solutions that address real consumer needs and bring greater comfort to everyday life."

CoolNest® Cooling Comforter & CoolNest® Ergonomic Cooling Pillow: Cooling Beyond the Mattress

The launch expands the CoolNest® portfolio beyond the mattress with two new cooling bedding products, each designed to address a different aspect of nighttime comfort. The CoolNest® Cooling Comforter combines advanced dual-cooling technology, silk-inspire fabric, and a lightweight comfort design to deliver cooler, drier comfort without the heavy feel of traditional comforters. The CoolNest® Ergonomic Cooling Pillow pairs precision neck and spinal support through its ErgoContour™ Neck Support Design with progressive cooling technology that provides an instantly cool feel and helps release heat throughout the night.

"A comfortable sleeping environment goes beyond the mattress. By expanding the CoolNest® portfolio into cooling bedding, we're taking another step toward creating a more complete cooling sleep experience across the bedroom," added Amber Zhu.
