Berkeley Ergonomics knit pillowcases are made from certified organic cotton. Soft knit made from organic cotton for breathable responsiveness Eliminates surface tension both for your mattress and pillows Machine washable at high temperatures for optimal hygiene Custom-made for us in Germany from long-staple organic cotton Made with 100% organic cotton. Good for the environment and your health Fitted design for a perfect fit Fits mattresses up to 11" thick Designed to work with your mattress and pillows Our mattresses and pillows are designed to provide maximum body conformation and pressure relief. While woven high thread count sheets and pillowcases conventionally are regarded as the ultimate choice, they will cause a certain amount of surface tension and contact pressure. On a pillow, this can mean ear pressure where you didn't feel any on the unencased pillow and a mattress might suddenly feel firmer. Our fitted sheets and envelope-style pillowcases are designed to provide stretch and breathable comfort. The long-staple organic cotton knit works with our mattresses and pillows to naturally balance body temperature and control humidity. Synthetic bedding materials and down are effective insulators that can trap humidity resulting in disrupted sleep due to overheating and night sweats. A dry and healthy sleeping climate allows your body to relax, reduce your heart rate and blood pressure and achieve more restful sleep. A well-ventilated, dry sleep environment also means fewer allergens like mold and dust mites, improving breathing. Clean comfort Like all our components the stretch cotton in our fitted sheets and pillowcases is certified chemically safe by Oeko-Tex Standard 100.
