What Every Type of Sleeper Needs For a Better Night's Rest

Can you keep a secret? Wool comforters regulate temperature, so they're the absolute best if you always sleep too hot or too cold. If you're a hot sleeper, this material will make you warm — but never, ever sweaty. (Likewise, if you get cold at night, wool will keep you toasty.) This Natural Home Australian Wool Twin Comforter ($115) has 100 percent wool fill and a combed cotton exterior, and while it seems impossible that one comforter would work for all four seasons, this one does.
