The pushchair 10 includes a back rest which is preferably formed of a single sheet 26 of a resilient plastics material such as 3mm thick polycarbonate or 2mm thick ABS so that the back rest is supportive when the pushchair 10 is erected and is flexed when the pushchair 10 is collapsed into a compact form for storage; the resiliency of the sheet 26 is such that the back rest returns to its flat supportive condition when the pushchair is re erected. The sheet comprises flexible plastics or fabric covers 34 and 36 and a layer 32 of cushioning material. Apertures 28 are provided to receive a safety harness and slots 30 facilitate flexing. <IMAGE>
