A device for releasably securing a tray to a chair having two extending arms with a plurality of consecutive recessed grooves on the underside of each arm which comprises a one-piece pivot bar; a pivot element for pivotably connecting the pivot bar to the bottom of the tray; the pivot bar comprising an operable front portion forward of the pivot element, a back portion rearward of the pivot element, and at least two pins extending from the back portion for engaging the grooves; attachment elements proximate the pivot element for rotatably securing the pivot bar to the bottom of the tray; and a biasing element associated with the pivot bar for urging the pins toward the bottom surface of the tray and into corresponding grooves when the tray is positioned on the arms of the chair to secure the tray to said arms, whereby operation of the pivot bar in opposition to the biasing means causes the pins to retreat from the grooves.
