A collapsible support frame (10) particularly for an infant pushchair comprises in an erect configuration at least a centrally located elongate spine (12) and a seating cavity (18) within the support frame in which to receive a seat. The spine being coupled at or towards one end to a coupler (20) and at or towards its other end to a handle assembly (22). The spine (12) comprises at least first and second, elongate, rigid spine members mutually interconnected at a pivot defining a moveable spine joint lying part-way along the length of at least one rigid spine member and, on at least one side of the moveable spine joint, subsidiary spine members each pivotably connected to one of the rigid spine members. The subsidiary spine members being pivotably secured together remote of the movable spine joint such that the spine defines at least one closed loop kinematic linkage being moveable between an erect configuration in which the rigid spine members and subsidiary spine members diverge and a collapsed configuration in which the rigid spine members and subsidiary spine members generally lie adjacent one another along their lengths. The connections of the rigid spine members and subsidiary spine members being such that the closed loop kinematic linkage is uniplanar.
