Abstract: A button forming assembly adapted for use in an upholstered cushion of the type comprising a backing, a flexible cover overlying the backing, and a layer of compressible padding material between the backing and the cover. The button forming assembly comprises a button forming member including a head portion in the shape of a button to be formed, and an attachment portion having a cross sectional area smaller than the cross sectional area of the head portion projecting from one side of the head portion. The cover is secured around the attachment portion with a part of the cover positioned smoothly around the head portion, and attachment means are engaged between the attachment portion and the backing through an opening in the padding material to retain the button forming member in place with the cover under tension and the padding partially compressed around the opening to shape the cushion.
