Pushchair which is moveable between an unfolded position and a folded position, comprising a structure with in particular two handle uprights (1, 1′), front legs (3, 3′), rear legs (5, 5′), seat supports (7, 7′), a backrest (2), and hinges (31-35, 41-47) for folding the pushchair flat. The pushchair also comprises a textile base (16), tensioners (18, 18′) for tensioning a front part (16a) of the textile base (16), a cover (19) with at least one main bow (20), and fixing elements (23, 23′) allowing each side of the main bow (20) to be fixed for example to a fixing point of the front part (16a) of the textile base (16) close to the tensioners. In the unfolded position, the backrest (2) is held against the seat supports (7, 7′) and can hold a child in the lying position facing the rear of the pushchair. In the unfolded position, the tensioners (18, 18′) are tensioned and allow deployment of the front part (16a) of the textile base (16) and the protective cover (19). On folding, the forward swivelling of the handle uprights (1, 1′) loosens the tensioners (18, 18′), causing the folding of the front part (16a) of the textile base (16) and the protective cover (19).
