Good bedding starts with good sheets. You can get 20 percent off the Luxe Sateen Core Sheet set in 21 colors across six sizes; they're some of our favorite sateen sheets thanks to their silky, cooling texture and thick, quick-to-warm weave. They're slick and slinky, and they warm up faster than traditional cotton sheets. If you don't love sateen or you don't need the warmth it provides, there's also a deal on crispy, crinkly percale sheets that WIRED bedding expert Nena Farrell recommends.
