Product Description
The Sweetnight CoolNest 14-Inch King Size Mattress is engineered to deliver cooler, deeper, and more restorative sleep through advanced cooling technology and ergonomic pressure relief. Designed with premium memory foam layers and a 5-zone support system, this medium-feel mattress adapts to different areas of the body to help reduce pressure buildup and improve spinal alignment.
Its exclusive CoolNest® cooling system combines gel-infused memory foam, breathable airflow construction, and temperature-regulating materials to help sleepers stay cool throughout the night. The mattress is designed for motion isolation and responsive support, making it a strong option for couples, combination sleepers, and hot sleepers.
The 14-inch profile offers enhanced cushioning and deeper contouring compared to standard foam mattresses, while CertiPUR-US certified foams ensure the mattress is made without harmful chemicals, heavy metals, or ozone depleters. Compressed and shipped in a box, the mattress expands fully within approximately 72 hours after unpacking.
