Delta Enterprise, of New York, N.Y.

Drop-Side: The cribs' drop sides can malfunction, detach or otherwise fail, causing part of the drop side to fall out of position, creating a space into which an infant or toddler can roll and become wedged or entrapped, which can lead to strangulation or suffocation. A child can also fall out of the crib. Drop-side incidents can also occur due to incorrect assembly and with age-related wear and tear. Mattress Support: The wooden stabilizer bars on some Delta drop-side and fixed-side cribs can be installed upside down, which puts extra stress on the crib and can cause the mattress platform to collapse, creating a gap in which an infant or toddler can become entrapped and posing a risk of strangulation or suffocation.
