The Consumer Product Safety Commission said Friday it has taken the first step to ban infant "bean bag" cushions because of 30 reported cases of babies found dead on them.

The commission voted Thursday to publish a notice of proposed rule making in which it will seek public comments to help it develop an accurate definition of the product.The cushions are filled with plastic foam beads or other granular material that can conform to the body of an infant, especially to the face, when the infant is placed stomach-downward.
