Abstract
Abstract A portable collapsible chair structure which, when erected, provides a full sized high chair for a small child, and when collapsed, folds into a compact, case-like package for handling and for storage. The enclosure of the case-like structure is useful for carrying articles normally required for the care of a child. The structure includes means permitting the chair back to be adjusted in height, and the tray and armrests may be retained in their stored position in the seat back when not required as when the seat is used by a larger child.
