This breakthrough crib liner keeps baby's limbs safely in the crib, while promoting healthy airflow. And no more guesswork: the new, universal design fits both slatted and solid standard cribs. Crib liner is made of soft, padded, breathable mesh that maintains better air access inside the crib. Attaches easily to the crib side panels with textured fasteners (a safer choice than ties). Hypoallergenic. Machine wash. Imported.
