A height adjustable pillow is a hypoallergenic pillow having a closable pillow case and preferably five cushions within that may be added or removed one at a time to adjust the height of the pillow. The top cushion is stitched diagonally corner to corner to make it easier to place an infant on the pillow so that the infant's head is able to rest comfortably in a chosen position without rolling to a less comfortable position.
