A comforter has a defined look and weight, and sometimes it can feel too light or too heavy depending on the season. But one of the top benefits of a duvet is you can slip almost any insert inside, like the Utopia Bedding down alternative duvet insert. It’s made from 100 percent microfiber with a synthetic fiber fill—which means it’s a great option for people who are allergic to down feathers. To buy: $29 with a coupon (was $40); amazon.com. The duvet insert is the number one best-seller in its category and has amassed 64,500 perfect ratings and over 14,600 five-star reviews. “This cloud-like duvet is so comfortable and soft,” one shopper said, adding that the product strikes an ideal balance between not being too heavy or too light, so they’re able to use it all year. The machine washable insert also includes a key feature—corner tabs—that you can use to tie it to any duvet cover and keep it in place. Also, the box stitching that appears throughout is not just there for added style. Instead, it helps to keep the filling from moving out of place while you sleep. Although the Utopia Bedding duvet insert is designed to go inside of a cover, you can also use it as a comforter. Choose from up to nine colors in sizes twin through California king—many of which are on sale right now—and give your bed a springtime spruce.
