Care Instructions & Use

Care Instructions

Pebble & Dimple: Turn SafeSleep™ cover inside out and zip up. Machine wash cover alone in cold water with mild detergent. Line dry or tumble dry on low heat. Do not use fabric softener, chlorine bleach or dryer sheets. Crib sheet optional.

Print: Unzip and remove cover. Machine wash ALONE on gentle cycle with gentle detergent. DO NOT use bleach, stain removers or fabric softeners. Dry ALONE on low heat. No dryer sheets needed for your print covers. Just like your favorite T-shirt, your print cover gets softer with each wash AND the benefits of your cover get re-invigorated!
