Say goodbye to sweaty nights! WIRED has rigorously tested a range of cooling mattresses to help you find the perfect sleep solution. From innovative tech to smart material design, these options are built to keep you comfortable and cool, no matter the temperature.
For those who find their current mattress a bit too warm but aren't ready for a full replacement, the BedJet 3 is a standout. This climate-control device blasts cool or warm air under your covers, offering a personalized sleep temperature without changing your bed. It’s a game-changer for sleepers who overheat easily.
In the hybrid category, the Casper Snow Hybrid impressed with its targeted support for back and stomach sleepers, thanks to a combination of poly foam, memory foam, and pocketed coils. While it initially had a slight shape and scent issue upon unboxing, it settled quickly into a supportive and comfortable sleep surface.
The Sealy Cocoon Chill Memory Foam Mattress, featuring a phase-change material, offers a noticeably cool surface and leans firm, making it a solid choice for back and stomach sleepers. Its minimal motion transfer is a bonus for couples who have different sleep schedules.
For budget-conscious shoppers, the Wayfair Sleep 12-Inch Medium Cooling Gel Memory Foam Mattress offers a balanced feel with its gel-infused foam and breathable knit cover, ensuring a consistently cool sleep. Similarly, the Wayfair Sleep 8-Inch Medium Cooling Gel Memory Foam Mattress provides excellent cooling and odor control at an incredibly low price point, punching well above its weight.
WIRED's testing methodology involves sleeping on mattresses for extended periods, often over two weeks, across different seasons and bedding. Beyond subjective comfort, the team assesses edge support, bounce, motion transfer, and crucially, how well the mattress manages trapped heat and promotes airflow, ensuring a truly cool and restful night's sleep.
