A KEY ELEMENT FOR CREATING A COMFORTABLE SLEEP ENVIRONMENT FOR YOUR CHILD: Crafted with love and care using 100% organic cotton fibers and printed with non-toxic dyes. Baby Atelier's Fitted Bedding Set can help you create a safe, cozy and healthy sleeping environment for your child. When your child goes to sleep on a bed covered with one of their organic fitted sheets and pillow cover, rest assured that you are not exposing him/her to any synthetic chemical or harmful substances. They not only source their materials from GOTS certified suppliers, but also abstain from using any chemical-based processes during the manufacturing, printing, and finishing processes. As a result, you get fitted sheets and pillow cover for children that are completely safe, super soft, breathable, durable, and oh so comfortable! To ensure the perfect fit, their bed sheets are fitted with thick elastic that goes all around the top and bottom of the sheet, and not just the edges.
