Removable tray for high chair

A method for attaching a tray assembly to a non-adjustable commercial high chair comprising the steps of:

• providing, a polymer tray having a main surface and a surrounding apron located continuously around a front and sides thereof, and a rear side free of apron so as to define a clearance region permitting direct engagement of a bottom face of the main surface with a top surface of armrests of the commercial high chair, a pair of opposing stop walls disposed rearward of the front and extending vertically from the bottom face and inwardly along the bottom face from the apron of each side, the stop walls having a rear surface thereof, and a strap assembly extending through a slot formed rearward of the stop walls in the surrounding apron on each of the sides and configured with an anchor feature that retains the strap in each of the slots, and having a buckle arrangement;
• engaging the tops of the armrests of the commercial high chair with the bottom face that extends continuously laterally to engage with at least a portion of the top surface of the armrests;
• positioning the polymer tray so that the rear surface of the stop walls interfere with front edges of each of the armrests in a predetermined front-to-rear position of the tray with respect to the high chair;
• and
• releasably attaching the strap assembly around a seat of the high chair to removably secure the bottom face of the tray, through a substantially downward retention force directly to the tops of the armrests of the high chair with the buckle arrangement.
