Overheating at night isn’t fun at any time, but in summer it’s doubly miserable. For cooler sleep on a smaller budget, Cocoon by Sealy is offering up to $540 off the Chill Mattress and $199 of free bedding. This cooling memory foam bed has a stretch-knit cover infused with phase change material to dissipate heat, so it doesn’t build up in the mattress. 

If you’re dealing with night sweats or hot flashes, you could upgrade to the Extra-Chill version (for an extra $300) with a premium, extra-cooling cover. With either version, you’ll get up to $199 of free cooling bedding - sheets and pillows. A queen size now costs $799 (was $1,239) at Cocoon, which is a fantastic price for a bed of this quality.

Cocoon by Sealy is one of the best mattresses in America for all types of sleepers, but especially if you love the contouring feel of memory foam yet get too hot when lying on it. The 100-night risk-free trial and 10-year warranty are average, but the lower price and free bedding bundle are far from average.

Save up to $540 - At $799 for a queen size plus $179 of free cooling bedding, this <a href="" data-link-merchant=""" data-link-merchant=""">Cocoon by Sealy mattress deal is fantastic value and will help you avoid sweltering through another summer of broken sleep. The Chill comes on a 100-night trial, giving you over three months to test it at home. If you like a bouncier bed, consider the hybrid version ($1,099 for a queen) instead.

If you’re looking for one of the best cooling mattresses for hot sleepers on a smaller budget, we highly recommend the Chill. It’s a fraction of the cost of competitor beds, though of course it won’t have the same cooling clout as premium models such as the Tempur-Pedic Tempur-Breeze or the Serta Arctic. 

As we explain in our Cocoon Chill Memory Foam Mattress review, this medium-firm bed is comfortable to sleep on, and we noticed a fresher, cooler feel from the cover compared to other memory foam mattresses we have tested. 

The Chill comes in either a 10” all-foam version or a 12” hybrid version (learn what is a hybrid mattress). We’d recommend the memory foam for maximum body contouring comfort and better motion isolation (so you and your partner won’t feel each other moving so much), and the hybrid for more bounce and response. Both deliver pressure relief plus cooling.

In addition to a stretch-knit cover infused with phase change material, the Cocoon by Sealy Chill uses Active Support Technology to direct support to the parts of your body that need it most. Think back, shoulders and hips. Fabric-encased coils reduce motion transfer, and the brand’s Quantum Edge technology provides a steel perimeter for better edge support. That makes getting in and out of bed easier.

There’s up to $540 off the Chill in this new mattress sale, plus you’ll get up to $199 of free cooling bedding with your purchase. This includes bed sheets and the brand’s best pillows for comfier sleep. This is a fantastic offer on a top-rated bed for cool sleepers, and one that could make a big difference to your summer slumber.
