Abstract
A rigid corner piece for maintaining the square appearance of a mattress having foam sides. The corner piece anchors two of the foam pieces together to form a butt joint. The corner piece is constructed and arranged to be relatively undetectable by a person sitting on the side of the bed. The corner piece preferably defines a groove into which the two foam pieces may be placed at a relatively right angle to each other.
