Abstract
A baby walker is provided and includes a base, seat for carrying a load, a frame operably connecting the base and the seat for permitting relative movement of the seat and the base between a fully collapsed position and at least two elevated positions, and a control system coupled to the base for selectively engaging the frame to position the seat in one of the at least two elevated positions to aid in preventing inadvertent movement of the seat to its fully collapsed position. The base includes a pair of eccentrically mounted pivot arms for lowering the base to a braking position upon movement of a support wheel on one of the pivot arms over an edge of an underlying surface.
