Abstract A folding device stroller includes a positioning seat securely mounted to an upper end of each of two front members and a retainer seat securely mounted to an associated end of a handle of the stroller, the associated end of the handle being pivotally mounted to the positioning seat. The positioning seat includes a transverse positioning ring formed on an upper end thereof and a spring-biased button partially received in the positioning ring. The retainer seat includes a cutout defined therein thereby forming a handgrip and a transverse bore defined in a lower end thereof through which the button is passable. The button is biased to a position partially received in the bore to retain the stroller in an extended position, and the stroller is foldable when the button is pressed inwardly to disengage from the bore.
