Abstract: A pushchair of the type which includes a chassis which is born upon one or more primary wheels on a primary wheel bearing axis, the chassis further having one or more forward and/or rear secondary wheel(s) or stabilizer(s) that in normal use of the pushchair during horizontal travel is/are not ground engaging but which limit tilting of the pushchair about the primary axis, the pushchair being characterized in that it further includes a selectively operable stabilizer which may be deployed to bring a prop into ground engagement to substantially prevent tilting of the pushchair about the primary wheel axis when the pushchair is stationary.
