Graco is recalling 1.2 million Harmony highchairs because they pose a fall hazard to children, the company and the U.S. Consumer Product Safety Commission announced on Thursday.

The highchairs' screws holding the front legs of the chair can loosen and fall out and the plastic bracket on the rear legs can crack causing the chair to become unstable and tip over unexpectedly.

Consumers should immediately stop using the Harmony high chair and contact Graco to receive a free repair kit, the CPSC said.

A total of 24 injuries have been reported, Graco said. Those include bumps and bruises to the head, a hairline fracture to the arm, and cuts, bumps, bruises and scratches to the body.

The company has received 464 reports of screws loosening or falling and plastic brackets cracking.

The Harmony chairs were produced from November 2003 to December 2009 and were sold at AAFES, Burlington Coat Factory, Babies R Us, Toys R Us, Sears, Target, Target.com, Wal-mart, WalMart.com, Shopko and USA Baby.
