Cribs sold under the Simplicity and Graco names are under recall.
The Consumer Product Safety Commission says there are two problems.
First, the design and instructions can lead people to incorrectly install the drop side of the crib, upside down.
Second, it increases the chance that the hardware used to attach the drop side can fail.
Infants are in danger of becoming entrapped and suffocating.
The cribs were made in China and sold in US stores from January 1998 to May 2007.
The recall involves brand names: Aspen, Nursery-in-a-box, Crib N Changer, Chelsea, Pooh, Ultra, Whitney and Trio.
Parents should immediately check to see if the drop side was installed right side up and is securely attached.
Simplicity will provide a free repair if the crib has older or broken hardware.
