A drywall cart for securely and safely carrying multiple sheets of wallboard is disclosed. The drywall cart broadly includes a platform for vertically supporting the wallboard, uprights for laterally supporting the wallboard, and casters for rollably supporting the platform and uprights. The platform includes a trough for receiving and supporting the wallboard. The trough minimizes the height of wallboard disposed in the drywall cart and thereby reduces the tendency of the loaded drywall cart to tip over. The minimal height of the wallboard is further enabled by attaching the casters laterally from the trough with outriggers. The outriggers extend from the trough and permit the trough to extend below a portion of the casters.
