A valve-actuated suction apparatus includes a resilient anchor member having an inner side arranged to seal against a reference surface, and an outer side. The anchor member includes a vent port extending between its inner and outer sides. The vent port includes a free end tubule formed on a free end of the anchor member stem. A movable member is slidably movable without rotation relative to the anchor member between a sealing position wherein the movable member blocks the vent port and a venting position wherein the movable member unblocks the vent port. The movable member includes a plunger valve that blocks the vent port by slidably engaging the free end tubule with an interference fit when the movable member is in its sealing position. A coupling connection between the movable member and the anchor member prevents detachment of the movable member from the anchor member.

Modular tray systems and methods of using the modular tray systems to support a variety of items either in a free-standing orientation or by securing the modular tray system to a chair. Such a modular tray system includes a tray and one or more features for supporting the tray with or from the supporting structure. The tray has a tray member, a base member connected to the tray member, an upper surface, a lower surface, and first and second connecting features defined in, respectively, the tray member and the base member at the lower surface of the tray. The supporting features include at least one of a support rod and a support throne that have third connecting features that are complementary to each of the first and second connecting features of the tray.
