You spend almost half your day in bed. If you spent that much time at the office, your desk chair would be the nicest thing you own, so why skimp on your bedsheets? The Classic Core Set is Brooklinen's original offering. These soft, cool sheets are made from a single ply, single pick construction with 60 count yarns. The 270 thread count sheets became the base of the brand's business after they tested over 100 other fabrics. Needless to say, this is one comfy set of sheets.
