Eucalypso founder Elle Liu knows firsthand that sleeping in the wrong sheets can be seriously disruptive. After having her sleep ruined by night sweats and waking up with breakouts, Liu dove into researching all things sheets and discovered some issues: Many cotton sheets are woven in a way that traps bacteria and sweat, and much of the cotton we use is grown and harvested unsustainably. In searching for an alternative, Liu came across Tencel — a silky, temperature-regulating fabric made of sustainably harvested and processed wood pulp — and knew she’d found her solution. She founded Eucalypso, which upends the traditional bedding-industry practices, from creating less-wasteful fabrics and fair labor practices to encouraging conscious purchasing by consumers. The result is a product you’ll love and use for years.
