An article holding tray adapted to retain and stabilize a wide variety of articles during their use such as dishware, drinking glasses, eating utensils, video game joy sticks and other articles which are typically usable on a tray or lap tray. The device includes a generally flat tray or board which includes one or more connected elongated slots formed orthogonally through the tray and sized in width for slidable translation of an elongated threaded fastener therealong. Each threaded fastener releasably retains an elongated movable retaining block in a selected position against an upper support surface defined by the tray. Each movable retaining block has at least one side surface, and preferably all of the side surfaces, which is sloped at an angle substantially greater than 90 degrees, and preferably about 105 degrees, with respect to the lower flat surface of the retaining block and the support surface. This creates a wedge effect which forces articles in contact with each surface against the support surface. Two or more such slanted side surfaces slidably and rotateably positioned at different locations against an edge or side of an article immobilize the article on the tray.
