Positioning apparatuses mountable to a wheelchair or other such device are disclosed. An illustrative positioning apparatus can include a base unit, a number of armatures each defining an extension of the apparatus, a number of rotatable joints adapted to permit movement of the armatures, and a platform adapted to support one or more objects. A number of actuation levers connected to the rotatable joints can be used to simultaneously unlock each of the joints in a single step, allowing the apparatus to be easily repositioned. A locking mechanism within each joint may permit one or more user-defined locking positions to be set on the joint. A temporary lock-out mechanism within each joint results in the unlocking of each joint until the armatures are rotated away from the locked position, allowing operation of the device with one hand.
