#1 Brand Independently Tested for Safety: From BreathableBaby, the original, patented breathable mesh liner with millions sold since 2002. Independently tested for safety by a 3rd party CPSC-accepted accredited laboratory. Helps Prevent Entrapment: Unlike padded crib bumpers, our mesh liners keep little limbs safely inside the crib without the risk of restricted airflow. And, also provide a visual shield to help provide a more peaceful night’s sleep. Not to mention, they keep pacifiers inside and within reach!
