WASHINGTON – The Consumer Product Safety Commission is recalling more than 770,000 children’s products, including the largest-ever recall of strollers.

Century Products of Macedonia, Ohio, is recalling about 650,000 strollers after receiving 681 reports of strollers collapsing or the carrier portion breaking loose, the safety commission said Thursday. Three concussions, two skull fractures and a broken elbow were among 250 injuries reported.

The recalled 4-in-1 strollers are for toddlers when used alone and for infants when a car seat-carrier is connected to the stroller. The safety commission said the carrier part of the product is safe when used only as a car seat.

Model names for the recalled strollers can be found on the footrest, the seat pad, the legs of the frame or on a white label on the side locks.

The names and model years of the recalled strollers are Take 2, 2000; Travel Solutions, 1999-2000; Pioneer, 1998-2000; Travelite, 1997-1998; Pro Sport, 1996-1999.
