The South African maker of molded foam seats that help babies sit up is recalling about 4 million of the chairs because of safety problems.

Babies can get hurt falling out of the seats.

If you have one of the Bumbo seats, you don’t have to throw it out or return it. Instead, the recall works a little like one for a car. Bumbo International Trust has a free fix that consists of a safety belt to keep kids in place.

You have to get those from the company, not the store where you bought the seat.

Bumbo’s repair kit also includes a warning sticker to remind parents and caregivers not to use the seat on raised surfaces, such as tabletops.

Don’t use the seats until they’re fixed, the company and the Consumer Products Safety Commission say.

For more details, including a video on how to repair the seats, see the Bumbo USA recall website.
