Real Simple's Editorial Guidelines Published on June 21, 2024 04:00PM EDT Photo: Real Simple / Francesca Fasciglione Let’s face it. Being a “hot sleeper” is no fun, especially in the heat of summer. You toss and turn, trying to get some relief, only to awake in the morning feeling sweaty and unrested. My husband and I used to have this issue, and we’d wake up drenched in sweat in the middle of the night. We both blamed the other for overheating the bed when the real problem was our heat-retaining mattress. You see, even high-end closed-cell memory foam mattresses can contribute to a hot night’s sleep due to the foam’s inability to breathe. On the other hand, mattresses made of breathable natural fibers, or cooling gel foam, absorb and redistribute body heat. All too familiar with the issue, my friend explained how she remedied her sleepless nights with a Extrasleep’s Cooling Gel Memory Foam Mattress Topper and a set of cooling sheets, a combination that transformed their sleep experience. They wound up buying the same toppers for her kids’ beds, too. After taking her advice, I bought it as well. And right now, the cooling mattress topper is currently marked down 43 percent at Amazon. Extrasleep Cooling Gel Memory Foam Queen Mattress Topper Amazon Orig. $140 $80 at Amazon When my topper arrived, I unrolled it and allowed it to sit for 24 hours to expand before placing it on our bed (at the manufacturer’s recommendation). The adjustable elastic corner straps attached easily to my existing mattress, ensuring the topper wouldn’t slide around when we slept. Extrasleep’s topper also came with a non-slip, machine-washable cover, so I didn’t have to worry about purchasing an additional mattress protector to keep things clean. As for the cooling features, Extrasleep’s topper is made of a 3-inch gel memory foam that boasts the highest air permeability, transporting heat away from the body as you sleep. It’s also topped with premium eco-friendly bamboo fabric that is extremely soft, moisture-wicking, and antibacterial. This naturally hypoallergenic fabric is especially suitable for those with allergies, eczema, or other skin conditions. One five-star reviewer called it the best mattress topper she’s ever tried, adding, “I am generally a hot sleeper and did notice that I stayed rather cool through the whole night… I slept like a baby and did not want or need to get out of bed!” With Extrasleep’s Mattress Topper, you don’t need to worry about mattress odor or toxicity, either. (Yes, it’s a real thing!) “If one of your determining factors to make the purchase is a chemical odor, I can assure you this one does not have an odor!” confirmed another shopper. This topper is CertiPUR-US certified and Oeko-Tex Standard 100 certified as well, assuring it’s manufactured without formaldehyde and is free of harmful levels of toxic substances. My nights spent tossing and turning due to overheating are now gone, and my husband sleeps more soundly, too. (I’m only awakened by his snoring, now.) And since this topper comes in five different sizes from twin to king, I’ll definitely be ordering them for all the beds in the house during this sale. It’s worth the small cost to stay cool year-round while preserving the life of our mattresses. Keep reading for more bedding accessories to help you sleep through the night sweat-free.
