People put a lot of pressure on their mattresses, and that’s one reason why, every major holiday weekend, the talk is all about getting a new one from the many home sales. Even if you treated yourself to a mattress upgrade (and especially if you didn’t), you shouldn’t forget about an often-overlooked item that can work wonders toward helping you get a quality snooze: the mattress pad. This affordable bedding accessory is an easy way to make your bed ultra-comfortable, which can make all the difference when it comes to getting a good night’s rest. But how do you know what to look for? Thankfully, Amazon reviewers have already put in the work, and they are in love with this best-selling mattress topper. Oh, and it just happens to be on sale for Prime Day.

Boasting every quality you could want in a mattress pad, this one has racked up nearly 25,000 five-star Amazon reviews. It’s cool, breathable, and super soft, and it makes any mattress — including hard, lumpy, bumpy ones — feel more luxurious. Says one reviewer, “I have had this for one month and still the best purchase for bedding I have ever made!!!! Holds its shape every day and I am no lightweight. Finally a great night’s sleep!!!”

What makes this topper so fantastic? To start, the hypoallergenic stuffing means it’s a great pick for anyone with allergies and other sensitivities. Its unique design is more supportive than a typical diamond quilting seam, which keeps the filling from moving around and bunching up. Some mattress toppers are a struggle to get on the bed, but this one has elastic fabric pockets for easy installation. And since it’s made from 100 percent high-quality fitted combed cotton — 300 thread count, to be exact — it delivers extra comfort and guards against heating up during the night. One memory-foam mattress owner raves, “I didn’t sweat or get hot at all when using flannel sheets on this baby with no fan on at night! This topper totally dissipates my body heat and doesn’t hold it, I love it!”

Nearly every reviewer couldn’t help but comment on how soft and fluffy the topper is. “This topper is like lying on a bed of marshmallows,” said one. “Not too soft but so comfortable I just don’t want to get out of bed.” To maintain maximum fluffiness, you can air the topper out in the sun for a few hours to puff it up, or, after giving it a spin in the washing machine, tumble dry it on low.

If you’re still on the fence about this game-changing bedding accessory, take it from this happy husband. “Unbeknownst to me, my wife decided to replace our mattress with the hardest slab of concrete on which I’ve ever had to sleep,” he shares. “I ordered this cover hoping for a tiny bit of relief. From the first night it exceeded all my hopes and dreams, I was able to sleep again, it doesn’t slip off even with my tossing and turning, and it stays cool… ” ‘Nuff said.
