It's a big world out there but your baby can sleep safe and secure in his or her own little world. Our crib bumpers fit standard cribs (using mattresses measuring approximately 28" x 52") and meet regulation standards with approximately 12" long ties and 2-3" thick batting so that you can rest easy-- at least when the little one does! Our crib bumper batting is made from recyclable hypoallergenic polyester fiberfill.
