These are 100% bamboo viscose sheets cut for a split-top king adjustable mattress, the kind Sleep Number sells. The fitted sheet has a 32-inch split from the top down and six corner pockets for mattresses up to 18 inches deep, plus fabric wings that cover the inner split so each side of the bed moves on its own. Bamboo viscose is silky, breathable and gentle on skin, which suits hot sleepers. The set includes a flat sheet, the split fitted sheet and two king pillowcases. Against cotton and microfiber split-top sets, the draw is the cooling feel and the wing coverage over the split; the trade-off is that bamboo viscose needs gentler washing and can wrinkle.
