The play yard's rocking bassinet attachment can tilt when secured by straps (non-rocking mode) which can cause it to stay tilted without returning to a level sleeping surface while in the rocking mode. The tilted sleeping surface can cause an infant to roll to the corner or side of bassinet and become wedged in the corner or pressed against the side or bottom of the bassinet. This presents a risk of suffocation or positional asphyxiation.
