For a wide double bed (180×200), our king bamboo sheets give you the room and the feel to match: a 206×206 cm fitted sheet with a 35 cm pocket, two pillowcases, and a 227×227 cm duvet cover. Each set is 100% natural bamboo fiber, woven at 300 threads per inch and OEKO-TEX certified, for a smooth surface that holds up wash after wash. Bamboo is one of the most breathable bedding fabrics there is — unlike microfiber, it doesn’t trap heat, which makes a king set comfortable even through warm summer nights. It’s a natural fit for couples where one person sleeps hot, and for anyone who wants sheets that still look and feel good a year in. New to bamboo?
