A bedroom with light green and beige wall paneling, a bed with a beige bed frame and white duvet, two nightstands, and a tall leafy plant.

Whether you've seen this method on TikTok too or are just intrigued by the name, I've got you covered with all the info you need to know. It's essentially just having your own separate duvet even if you're sharing a bed, which can help control temperature and therefore improve sleep. I've asked sleep pros for the pros and cons, plus rounded up our top comforters.
