Coyuchi offers bedding that is 91.5% plant fibre across 206 distinct styles scanned. The rest breaks down as 8.5% animal fibre. Coyuchi’s sheets, duvet covers and pillowcases are 100% GOTS certified organic cotton or organic French linen, with undyed options and no bamboo, Tencel or polyester, and on their own they are an excellent plant fibre choice. Under the Throne Standard of completely chemical and synthetic free bedding, Coyuchi does not fully pass, because its bedding range also includes wool, down and alpaca comforters, bed blankets and duvet inserts, which are animal fibre, and its Cloud Soft line carries a bio based softener marketed as wrinkle resistant.
