A collapsible stroller chassis has two laterally arranged scissor frameworks, which form a top part, and a substructure, which bears the wheel axles. The substructure and the facing ends of the scissor arms of the scissor frameworks are connected to one another by articulations such that, at least in the erected state of the top part, an effectively rigid structural unit is formed by the substructure and by the top part.
