Evenflo Company Inc. is recalling thousands of its high chairs.

About 643,000 Evenflo Envision High Chairs have been recalled because the recline fasteners and metal screws on both sides of the high chair can loosen and fall out, allowing the seatback to detach or recline unexpectedly. Children can fall backwards or fall out of the high chair and suffer bumps and bruises to the head, abrasions, cuts and bruises. Detached hardware also poses a choking hazard to children.

Evenflo has received 320 reports of seatbacks detaching or reclining unexpectedly, resulting in 19 reports of bumps and bruises to the head and 35 reports of other injuries including abrasions, pinches and bruises. Evenflo has also received 13 reports of recline fasteners and screws falling out of the high chair, resulting in one incident in which a fastener and/or screws were found in a child's hand or mouth but were removed before choking occurred.
