The queen-size sheet is terrific. One piece, no seams. I slip the fitted corners right over my bedding, including blanket & duvet cover, no problem. Comfortable to play on; not clammy or chilly to the touch. And easy to clean, whether just a few grease spots wiped down with Simple Green; or, if really messy, machine wash in warm water, low or line dry.
