Recall of more than four million Bumbo baby floor seats after scores of injuries

The maker of the popular Bumbo baby seat is issuing a voluntary recall of more than 4.6 million of the foam mini-chairs.

The move follows reports about scores of injuries, including skull fractures, the company says.

Consumers should stop using it until they install a free repair kit, which includes a restraint belt and a new warning sticker, and never use the Bumbo seat on an elevated surface, the South Africa-based firm, Bumbo International Trust, said.

The warnings were echoed by the United States Consumer Product Safety Commission and Health Canada.

The recall involves about 4.3 million Bumbo seats in the US and about 340,000 in Canada, as well as an unknown number sold elsewhere.
