Abstract
A foldable baby stroller that can comprise collapsible telescoping support shafts connected by a hinged handle. Pivot assemblies support the support shafts and two pairs of legs including at least one pair of rotating legs and one pair of fixed legs, each leg including an attached wheel. The pair of rotating legs when in a closed configuration fit below, adjacent, and parallel to the fixed pair of legs with the attached respective wheels of each pair arranged in tandem. A hinged support brace links the pair of pivot assemblies and locks in an extended configuration. Two seat supports attaching a seat to the stroller and fold upward 90° to facilitate configuring between the extended configuration and folded configuration by folding upward. The pivot assemblies facilitate folding the support shafts when in the retracted configuration, and the two pairs of legs when in the retracted configuration, together into the folded configuration.
