“I am one of those people that generates a lot of body heat when I sleep, so I am happy to report this mattress pad has been perfect,” one reviewer wrote. “It does not make me hot at night! I guess that “cooling ultra-tech bamboo blend” really does work. Highly recommend this product!” To buy: $45; amazon.com. “Recently purchased a nice 10 inch memory foam type mattress. Loved the support it provides, but woke up hot each morning, ugh!” another chimed in. “This mattress protector solved that—it makes my new mattress feel comfortable like it should. I wake up refreshed instead of sweaty. If you need to cool down your memory foam, this will do the trick.” And unlike other options on the market, this cooling cover provides heavy duty protection against spills and allergens, but it feels—and sounds—like nothing is there. “I am very picky when it comes to these because I cannot stand sleeping on something that crinkles or feels like you’re sleeping on plastic,” one reviewer wrote. “This protector is so soft to sleep on and easy to wash. I feel like I’m sleeping on my mattress alone.” While nothing will stop you from sweating entirely, investing in this $45 mattress topper will help to keep things cool and protect one of the most expensive pieces in your home. And it may be just the thing to help you sleep through the night, which in our books, is priceless.
