An infant's feeding mat is provided with a substantially flat bottom and an upstanding ridge lying within a marginal zone adjacent the peripheral edges. The mat is formed of a base ply of foamed resilient flexible plastic and a top ply of nonfoamed flexible plastic. A thick border strip of foamed flexible resilient plastic is interposed between the plies and within the marginal zone, and the two plies are subsequently heat sealed to one another along their peripheries. An additional heat sealed seam between the plies surrounds the inner border of the strip and encloses the strip. The strip is held under compression between the plies and imparts the ridge to the mat.
