A tray table apparatus including a tray table and a tray table support assembly coupled to the tray table. The tray table and the tray table support assembly are configured to transition between a stowed position and a deployed position. The tray table support assembly includes: a support shelf; a support arm having a first end pivotably coupled to the support shelf so as to be pivotable about a first pivot axis and a second end, the tray table pivotably coupled to the second end of the support arm so as to be pivotable about a tray table pivot axis; and an adjustable pivot stop positioned to limit pivot movement of the support arm about the first pivot axis in the deployed position, such that a selected adjustment position of the adjustable pivot stop determines an angle of inclination formed between the support arm and the support shelf.
