You'll always be dreaming with our Saturday Park Sesame Street full size sheet set with Elmo, Cookie Monster, Big Bird and Oscar the Grouch! Made of 100% GOTS certified organic cotton and OEKO-TEX certified, you can sleep well knowing our sheets have been tested for over 300 harmful chemicals and synthetics. Our sheets are composed of durable long-staple cotton with a crisp percale weave that gradually softens over time. Four piece set includes one fitted sheet, one flat sheet, and two standard pillowcases. To clean machine wash cold. To dry, air dry or tumble dry on low.
