ABSTRACT:
Tray assembly for attachment to folding chairs and other supporting structures. The tray assembly includes a base adapted to be mounted on a supporting structure, a support arm which is mounted on the base, and a tray which is mounted on the support arm. The support arm has first and second cylindrical mounting pins which are received in tight frictional engagement in semi-cylindrical mounting ferrules on the base and the tray. The pins can be rotated within the ferrules to move the support arm and table to different angular positions relative to the base and the support arm, with the support arm and the table being held securely in the different positions by the frictional engagement between the pins and the ferrules.
