PRIORITY 
     This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/692,515, filed Aug. 23, 2012, which is expressly incorporated by reference herein. 
    
    
     BACKGROUND 
     The present disclosure relates to a juvenile seat, and particularly to a juvenile seat assembly including a seat and seat-support legs coupled to the chair. More particularly, the present disclosure relates to a high chair for young children. 
     SUMMARY 
     According to the present disclosure, a juvenile seat assembly includes a seat bottom and legs for elevating the seat bottom above the ground to support a child seated on the seat bottom in an elevated position above the underlying ground. In illustrative embodiments, the juvenile seat assembly further includes a seat back arranged to extend upwardly from a rear edge of the seat bottom. 
     In illustrative embodiments, the juvenile seat assembly is a high chair adapted for use to feed young children. The juvenile seat assembly includes separate and spaced-apart first and second molded side frames that are molded of a plastics material to include slots or other fixtures sized to receive and orient portions of other components. These other components include, for example, a footrest, a rear strut, a seat bottom, and a seat back. In illustrative embodiments, these other components are made of wood. Fasteners are used to retain these wooden components in predetermined fixed positions relative to the spaced-apart first and second side frames so that the wooden components cooperate with the molded side frames made of a plastics material to form a high chair that appears to an observer to be made primarily of wood. In other embodiments, these other components are made of any suitable material. 
     In illustrative embodiments, a tray unit is mounted for sliding movement on a first armrest provided by the first molded side frame and on a second armrest provided by the second molded side frame. Each molded side frame is molded using a plastics material to form outwardly facing latch-receiving slots sized to receive inwardly extending lugs included in latches mounted on a slidable tray top for movement into and out of the companion latch-receiving slots at the option of a caregiver. In an illustrative embodiment, these outwardly facing latch-receiving slots are formed in an outer shell that is coupled to an outboard portion of a companion armrest. The tray top is arranged to slide on the armrests toward and away from the seat back. The latches are movable relative to the slidable tray top to engage the latch-receiving slots formed in the outer shells that are coupled to armrests to retain the slidable tray top in one of several predetermined positions on the armrests. 
     Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
