100% organic cotton cover is not pre-shrunk, but is cut slightly larger to allow for some shrinkage. However, we still recommend washing and drying with no heat. If your cover already fits a bit snug, air dry only is recommended. If your cover fits a bit loose on the foam, low heat is suggested. After the first wash, the cover should fit perfectly snug and stretch out after just a few plays.
Spot clean natural latex foam with mild soap and water. If the natural foam is put into direct sunlight or exposed to air for several weeks, it will begin to dry out and become brittle. If your natural foam becomes wet, remove the cover and let the components dry separately in a room.
