A high chair comprising: a seat assembly including a rear support surface and a lower support surface; a tray connected with the seat assembly; a leg assembly connected with the seat assembly, the leg assembly being configured to support the seat assembly above a floor surface; a button (100, 200) pivotally connected with the tray or the seat assembly; a linkage (102, 202) including a first end (130, 230) and a second end (132, 232), the first end (130, 230) of the linkage (102, 202) being pivotally connected with the button (100, 200), wherein pivotal movement of the button (100, 200) about a button pivot axis (114, 214) results in pivotal movement of the linkage (102, 202) about a linkage pivot axis (134, 234), which is spaced from the button pivot axis (114, 214); a cable (104, 204) including a first end (140, 240) and a second end (142, 242), the first end (140, 240) of the cable (104, 204) being connected with the second end (132, 232) of the linkage (102, 202), wherein pivotal movement of the button (100, 200) about the button pivot axis (114, 214) results in translational movement at the second end (132, 232) of the linkage (102, 202), which results in movement of the cable (104, 204) in an unlocking direction; a locking member (106,206) connected with the second end (142, 242) of the cable (104, 204) and releasably coupled with the seat assembly or the leg assembly, the locking member (106, 206) being moveable between a locked position where the locking member engages the seat assembly or the leg assembly and an unlocked position where the locking member (106, 206) is disengaged from the seat assembly or the leg assembly, wherein movement of the cable (104, 204) in the unlocking direction results in movement the locking member (106, 206) toward the unlocked position. a seat assembly including a rear support surface and a lower support surface; a tray connected with the seat assembly; a leg assembly connected with the seat assembly, the leg assembly being configured to support the seat assembly above a floor surface; a button (100, 200) pivotally connected with the tray or the seat assembly; a linkage (102, 202) including a first end (130, 230) and a second end (132, 232), the first end (130, 230) of the linkage (102, 202) being pivotally connected with the button (100, 200), wherein pivotal movement of the button (100, 200) about a button pivot axis (114, 214) results in pivotal movement of the linkage (102, 202) about a linkage pivot axis (134, 234), which is spaced from the button pivot axis (114, 214); a cable (104, 204) including a first end (140, 240) and a second end (142, 242), the first end (140, 240) of the cable (104, 204) being connected with the second end (132, 232) of the linkage (102, 202), wherein pivotal movement of the button (100, 200) about the button pivot axis (114, 214) results in translational movement at the second end (132, 232) of the linkage (102, 202), which results in movement of the cable (104, 204) in an unlocking direction; a locking member (106,206) connected with the second end (142, 242) of the cable (104, 204) and releasably coupled with the seat assembly or the leg assembly, the locking member (106, 206) being moveable between a locked position where the locking member engages the seat assembly or the leg assembly and an unlocked position where the locking member (106, 206) is disengaged from the seat assembly or the leg assembly, wherein movement of the cable (104, 204) in the unlocking direction results in movement the locking member (106, 206) toward the unlocked position.
