This Snuggle Me® Infant Lounger Cover is made with soft 100% organic cotton to protect your lounger from minor leaks and spills. It is made to easily slide on and off your lounger for quick washing, and to easily switch up colors. Washing Care: Machine wash on a cold gentle cycle with gentle dye free detergents. Do not pour detergent directly on the cover. Wash by itself, and disable top loaders with agitators. Air dry on a flat surface until damp, then tumble dry on low. Adding heat to any of our covers will shrink them.
