After Ikea chests tipped over and fell and fatally injured two children, safety regulators say consumers should stop using Ikea's dressers and chests for children unless the products are mounted to a wall.

The Swedish furniture giant is offering a free kit to help consumers do that. The kit will be available to consumers who bought 27 million chests and dressers.

Ikea and the U.S. Consumer Product Safety Commission say two boys, both about two years old, died in 2014 after chests that had not been secured to walls tipped over and fell on them.

They say consumers shouldn't use children's chests and drawers taller than 23 1/2 inches and adult chests and drawers taller than 29 1/2 inches unless they are securely anchored to the wall.
