A tray assembly includes an articulatable arm assembly coupled with a tray and selectively held in place by a locking mechanism (e.g., a locking gas spring). A release mechanism coupled with the tray selectively activates and deactivates the gas shock mechanism and is coaxial with and free rotating with respect to an axis of rotation of the tray. The tray may rotate between a horizontal position and a stored position substantially orthogonal to the horizontal position. The arm assembly may include at least one frictional hinge comprising a tapered pin, a tapered bushing in rotational frictional contact with the tapered pin, and an adjustment mechanism coupled to the tapered pin to provide adjustable contact force between the tapered pin and the tapered bushing.
