Abstract: In an infant-safe comforter fitted to the foot end of a crib mattress, the grasping power of the two boxed corners of the comforter on the corners of the mattress is controllably reduced by limiting the extent of an elasticized central segment of the free edge between the two corner seams in the foot end of the comforter. The terminal points of this elasticized central portion are spaced 11/2 inches inboard from each of the corner seams. The nudging head of an infant crawling under the comforter to the foot end raises the free edge above the bottom perimeter bead of the mattress to admit access of air under the comforter and releases the grasp at the corners to prevent asphyxiation under a comforter of low air permeability.
