According to some embodiments, an apparatus includes a first tray portion and a second tray portion able to be configured with the first tray portion in an expanded tray configuration. Moreover, an attaching portion (e.g., a clamp) is coupled to at least one of the first and second tray portions and is adapted to be removably attached to a tabletop. Such an arrangement may help a person in a wheelchair utilize the tabletop even when the wheelchair is unable to fit under the tabletop.
