Abstract: A product display unit (10) has a product support surface of selectively adjustable area. The unit comprises an attachment (13, 14) for securing to a support structure (15) and a cantilevered support member (11) extending from the attachment in a first length direction. A plurality of elongate support arms (23) extend lengthwise in a direction substantially perpendicular to said first length direction. Each support arm (23) is pivotably attached to the cantilevered support member for movement between a first position and a second position to vary the area of the product display unit available to support product. Each support arm may also be telescopically movable from the second position to a third position to further vary the product support area.
