Plum sheet options are made from microfiber, 100% viscose (from bamboo), and a rayon-from-bamboo blend that includes polyester.
Fitted-pocket depths vary by set, commonly 16", 17", 19", and up to 21" for extra-deep options.
Plum sheets are offered in Twin and Twin XL, Full, Queen, King, California King, and some listings include Split-King.
Most plum sheet listings recommend simple machine care: machine wash and tumble dry.
Bamboo viscose options commonly list a 300-thread count and a sateen weave. Microfiber options typically indicate thread count as not applicable.
Bamboo viscose sheets are marketed as breathable and moisture-wicking for cooling comfort, and some product bundles are explicitly sold as cooling sets.
