Bamboo fitted sheets are typically made either from 100% viscose (rayon) derived from bamboo or from blended fabrics. Some blended options list about 60% viscose from bamboo combined with microfiber.
Bamboo fitted sheets are offered in deep-pocket and extra-deep-pocket options. Deep-pocket versions commonly fit mattresses around 16 inches deep, while extra-deep options typically accommodate up to about 19 inches.
Care instructions on listings typically say the sheets are machine washable and can be tumble dried. Blended sets are likewise labeled as machine washable and dryable.
Listings describe deep-pocket construction plus reinforced elastic—heavy-duty non-slip elastic straps at the corners and thick elastic around the sheet—to help keep the fitted sheet secure.
Some viscose-from-bamboo listings show OEKO-TEX certification numbers and explicitly state OEKO-TEX certification. Other listings (often blended products) describe using organic bamboo-derived viscose or otherwise call out eco-friendly materials.
A fitted-sheet-only listing shows a package quantity of one fitted sheet. Full sheet sets are sold as multi-piece packages (for example, listings may show 3-piece or 6-piece sets that include a fitted sheet, a flat sheet, and multiple pillowcases).
