WASHINGTON — Ikea is recalling 29 million chests and dressers that can easily tip over and trap children underneath. Six children have been killed and three dozen others injured, and federal safety officials Tuesday urged consumers to take immediate action.

The Swedish retailer issued the recall Tuesday, saying the furniture can pose “a tip-over and entrapment hazard that can result in death or injuries to children” if not properly anchored to a wall.

“Consumers need to act immediately because it’s a very present hazard, especially if you have kids in your home,” Elliot Kaye, chairman of the Consumer Product Safety Commission, said in an interview.

Kaye said consumers “need to either get their anchor kit from Ikea for free and install it on their furniture, take it back to the store for a full refund or have Ikea come and pick it up from their homes for free.”

The recall, which only applies to customers in the U.S. and Canada, is for several types of Ikea chests and dressers, including the Malm line. Ikea said the units under the recall are children’s chests and drawers taller than 23.5 inches and adult chests and dressers taller than 29.5 inches.

The recalled units were sold at Ikea stores “at various times through June 2016,” the company said.

All of the children killed were 3 years old or younger, the CPSC said. One child was killed about 27 years ago. The other deaths were more recent, between 2002 and 2016. The CPSC said it received 36 reports of injured children.

Ikea said it will give a full refund to owners of recalled chests and dressers made between 2002 and 2016. For recalled units made before 2002, customers can receive a store credit for half the original price.
