We claim: 1. A high chair, comprising: a frame; a seat; a tray positioned a distance above the seat; an actuator to adjust the distance between the seat and the tray; and a post slidably suspending the seat, wherein the actuator releasably secures the seat to the post to define the distance. 2.

We claim: 1. A high chair, comprising: a frame; a seat; a tray positioned a distance above the seat; an actuator to adjust the distance between the seat and the tray; and a post slidably suspending the seat, wherein the actuator releasably secures the seat to the post to define the distance. 2. A high chair as defined in claim 1, wherein the frame is structured to stand upright when folded. 3. A high chair as defined in claim 1, wherein the actuator is a threaded knob. 4. A high chair as defined in claim 1, wherein the actuator is a spring biased pin. 5. A high chair as defined in claim 1, further comprising a connector slidably coupling the seat and the tray to the frame to enable height adjustment of the seat and the tray relative to a ground surface. 6. A high chair as defined in claim 5, wherein the connector includes a release mechanism to releasably secure the seat and tray at a fixed height relative to the ground surface. 7. A high chair as defined in claim 6, wherein the frame includes a leg having a plurality of apertures, and wherein the release mechanism includes a pin that is dimensioned to engage at least one of the plurality of apertures to secure the seat and tray at the fixed height. 8. A high chair as defined in claim 1, further comprising: a crossbar carrying at least one of the seat and the tray, and a footrest coupled to the cross-bar via an extension, the footrest being adjustable along a length of the extension. 9. A high chair comprising: a frame; a seat; a tray positioned a distance above the seat; an actuator to adjust the distance between the seat and the tray; a crossbar carrying at least one of the seat and the tray; a footrest coupled to the cross-bar via an extension, the footrest being adjustable along a length of the extension; and a spring biased pin to releasably secure the footrest to the extension. 10. A high chair as defined in claim 1, further comprising a crossbar carrying the seat, the seat being rotatably coupled to the crossbar. 11. A high chair comprising: a frame; a seat; a tray positioned a distance above the seat; an actuator to adjust the distance between the seat and the tray; and a crossbar carrying the seat, wherein the seat is rotatably coupled to the cross bar by a joint, the joint comprising: an inner gear wheel; an outer gear wheel engageable with the inner gear wheel to lock the seat against rotation relative to the crossbar; and a cam; wherein the cam is actuatable to disengage the inner gear wheel and the outer gear wheel to release the seat for rotation relative to the crossbar. 12. A high chair as defined in claim 11, further comprising a lever to actuate the cam. 13. A high chair as defined in claim 12, wherein the lever is disposed on a rear of the seat. 14. A high chair as defined in claim 1, wherein the seat further comprises: a seat pan; a seat back; and a post to adjustably couple the seat back to the seat pan. 15. A high chair as defined in claim 14, further comprising an actuator coupled to the seat back to selectively release the seat back for movement relative to the post. 16. A high chair as defined in claim 1, further comprising a harness including shoulder straps. 17. A high chair as defined in claim 16, wherein the seat further includes a crotch post and the harness is coupled to the crotch post. 18. A high chair as defined in claim 1, wherein the tray further comprises: a base tray; and a top tray coupled to the base tray. 19. A high chair comprising: a frame; a seat; a tray positioned a distance above the seat; a first actuator to adjust the distance between the seat and the tray; and a second actuator disposed on a rear of the seat and actuable to move a foldable bolster wing between an extended position and a retracted position. 20. A high chair as defined in claim 1, wherein the seat comprises a slick foam. 21. A high chair as defined in claim 20, wherein the seat is molded as a unitary structure. 22. A high chair as defined in claim 1, further comprising a fabric support for the seat. 23. A high chair as defined in claim 1, wherein the seat defines a slot and is shaped to funnel spills toward the slot. 24. A high chair as defined in claim 23 further comprising a catch basin removably secured beneath the slot.
