A convertible double stroller comprising a pair of cross bars pivotally connected at a common vertex connected to a pair of telescoping rods creating a generally hour-glass shaped frame assembly having a front end and a rear end, a plurality of wheels attached to the frame assembly, a handle bar attached to the frame assembly rear end, and a pair of seat mounts fixedly attached to each of the telescoping rods, wherein the convertible double stroller may be selectively transitioned between three configurations: (a) a seated configuration wherein the frame assembly is in a fully expanded position thereby positioning the seat mounts in a side-by-side placement for seating; (b) a seated configuration wherein the frame assembly is in a moderately expanded position thereby positioning the seat mounts in a front-to-rear placement for seating; and (c) a storage configuration wherein the frame assembly is in a fully collapsed position for storage.
