Ideal for school cots and to adapt throughout the year's temperature variations. This kit replaces sheets and blankets in a single piece. It prevents children from uncovering themselves constantly and sheets from dragging on the floor. A sheet with an envelope system, duvet cover, and removable duvet (includes the duvet). If you already have our duvet, you have the option to purchase this sheet without the duvet. They arrive at nap time and can lie down and cover themselves independently, relying less on the educators. Increases hygiene and comfort. With four elastics to attach to the cot or mattress. Made of 100% cotton.
