Graco is recalling 1.2 million of its Harmony high chairs after 24 children were injured in tip-over accidents caused by a defect in the chairs. One of the children suffered a hairline fracture to the arm while others sustained bumps, bruises and scratches to the head and body. Astoundingly, there were 464 reports of the high chairs coming apart before the recall.

The screws holding the front legs of the high chair can loosen and fall out and/or the plastic bracket on the rear legs can crack causing the high chair to become unstable and tip over unexpectedly, according to the recall notice from the Consumer Product Safety Commission.

This recall involves all Harmony high chairs. They were manufactured from November 2003 through December 2009 and on the market until this month. They are no longer in production. Multiple model numbers are affected (check the recall notice for details). The model number can be found on the label on the underside of the foot rest.

Retailers that sold the seats include AAFES, Burlington Coat Factory, Babies "R" Us, Toys "R" Us, Sears, Target, Target.com, Walmart, WalMart.com, Shopko and USA Baby.

The CPSC is telling parents and caregivers to stop using the high chair and contact Graco to receive a free repair kit at (877) 842-3206 or via Graco's Web site.
