Beginning June 28, 2011 all cribs sold in the United States must meet new federal requirements for overall crib safety. These 5 new Federal Requirements address more than just drop-sides. Mattress supports, slats and hardware on all cribs are now required to be more durable and manufacturers have more stringent testing requirements to prove compliance.
