Abstract: An apparatus comprises a frame and a plurality of wheels. A handle is pivotally joined to the frame. An adjustment mechanism is joined to the frame and the handle. The adjustment mechanism supports the handle at a plurality of angles. A seat assembly is configured to seat the occupant. The seat assembly is slidably joined to the handle. A locking mechanism secures the seat assembly in a first position with the seat assembly resting on the frame and the adjustment mechanism supporting the handle at an angle to recline the seat assembly in which the apparatus is configured as a stroller. The locking mechanism further secures the seat assembly in a second position with the seat assembly supported above the frame and the adjustment mechanism supporting the handle at an angle to position the seat assembly in an upright position in which the apparatus is configured as a highchair.
