A review of various cooling mattresses and sleep climate-control devices, evaluating their temperature regulation, support, and overall comfort for different sleeping positions.
Key facts
- •The Nolah Evolution Hybrid ranges in price from $1,460 for a twin to $3,454 for a split king.
- •The BedJet 3 climate-control device costs $427 and is designed to regulate temperature without requiring a new mattress.
- •The Casper Snow Hybrid requires approximately two days to fully expand and dissipate initial packaging odors.
- •Wayfair offers multiple cooling gel memory foam mattresses, with prices ranging from $326 to $550 for various models.
- •Hybrid mattresses generally retain less heat than all-foam models due to the inclusion of coil systems that promote airflow.
Wired tested a variety of mattresses and sleep accessories to identify effective options for hot sleepers. The Nolah Evolution Hybrid is highlighted for its balance of spinal support and cooling features, while other products ranging from memory foam mattresses to climate-control devices were evaluated for their ability to manage heat and provide comfort.
By the numbers
Top Mattress Recommendations
The Nolah Evolution Hybrid features a standard organic cotton and cooling fiber cover, with an optional GlacioTex-fiber upgrade for extra cooling. It utilizes AirFoam and gel-infused foam to prevent heat trapping, supported by pocketed coils and a mesh gusset for ventilation. Other models tested include the Casper Snow Hybrid, which provides targeted support for back and stomach sleepers, and the Sealy Cocoon Chill, which uses phase change material to draw and store body heat. Budget-friendly options from Wayfair were also reviewed, such as the 12-inch Medium Cooling Gel Memory Foam Mattress and the 13.5-inch Medium Cooling Gel Memory Foam Mattress. These models often incorporate gel-infused foams and breathable knitted covers to aid in airflow and temperature regulation.
Alternative Cooling Solutions
For those who prefer to keep their existing mattress, the BedJet 3 climate-control device is an alternative. It uses a blower unit placed under the bed to circulate hot or cool air beneath the covers. Other mattresses like the Tuft & Needle Mint Hybrid and the Saatva Memory Foam Hybrid were also tested, with varied results regarding their long-term cooling sensations and lumbar support.
Testing Methodology and Selection Criteria
Testing involved sleeping on mattresses for at least half a month, assessing factors such as motion transfer, edge support, and overall heat retention. Key features to consider when choosing a cooling mattress include material composition—such as gel or copper-infused foams—and the use of hybrid designs that incorporate coils to improve airflow. Cover fabrics made from moisture-wicking or phase-change materials are also noted for their ability to regulate temperature.
