A product display system includes a product-support structure with a plurality of cabinets, a plurality of spacers, a base tray, and a cover plate. The cabinets and spacers are inserted into a cavity in the base tray in an alternating pattern around a peripheral wall of the base tray and the cover plate is placed on a top end of the spacers and cabinets, opposite the base tray. The product display system includes a display header that is slidable along a vertical axis with respect to the product-support structure. The display header includes an elongated header tube which includes sidewall panels.
The product display system can include one or more elastic members that connect the display header to the product-support structure and bias the display header to an upright position.
