Flannel sheets are the best sheets for cooler winter nights. They're soft and cosy, but they also keep you warm. That's because the flannel is made of thicker cotton that has a denser weave than regular cotton sheets, so it traps more heat in your bed and keeps you toasty all night long.There are also microfibre flannel sheets available, which are less expensive than traditional cotton flannel sheets. And if you're looking for a whole new set of bedding, we have a wide range of flannelette quilt covers available as well!
