Still searching for a solution to those hot summer nights? Fans and the best portable air conditioning units are nice, but they might not be enough to keep you from a restless, sweaty sleep. Instead, you should look for something that stops the problem where it begins: bedsheets. Sure, using sheets when your bedroom feels more like the inside of an oven might not sound appealing, but that’s where cooling sheets and comforters come in. 

More specifically, Costco’s Sutton Place cooling comforter has rave reviews from many buyers — and it doesn’t break a budget, either. Starting at $49.99 for a queen and $59.99 for a king, the Sutton Place cooling comforter comes in white and gray. It features cooling fabric on both sides of the comforter that, according to many of the comforter’s reviewers, help you regulate your temperature while you’re asleep so you stop waking up sweaty. Wondering whether cooling sheets really work on hot nights? Costco customers have answers: “I bought mine a month ago and it WORKS! [sic] It stays cool all night. I love it,” reads one comment on a TikTok showing off the Sutton Place comforters in a Costco. Another review from Costco’s website added that “every time I moved the blanket you could feel the coolness.” Could this comforter be the energy-efficient way of saving your summer?

Costco’s cooling comforter isn’t composed of your typical organic cooling materials such as cotton or silk. Instead, the Sutton Place cooling comforter is made with polyester and nylon. This came as a surprise to some customers, since cooling sheets are typically made of more breathable materials. However, polyester generally works as a moisture-wicking fabric rather than a breathable one, which explains why Costco’s cooling comforter works so well. The comforter is machine washable, another bonus for those who don’t want to deal with the struggle of successfully removing and cleaning a duvet. Reviewers tend to agree that the fabric is soft and comfy, though some also add that it can be a little bit slippery; you might want to visit a Costco store near you to see and feel the fabric for yourself before you buy.

As with every product, not all customers are equally satisfied with their cooling comforters. While Costco’s online reviews are generally positive, some social media commenters say that the comforters’ cooling powers stopped working after a wash or two. Others said that it just didn’t do enough to keep them cool. Fortunately, Costco has a fairly generous return policy; you can always confirm your comforter is returnable at checkout, and bring it back if you’re not a fan.
