Abstract
Abstract A baby carriage stroller has a hollow main body which is mounted on wheels. Parallel pivot arms connect an upper body portion with the main body for movement between an extended upper position and a lower storage position in which the upper body portion is contained within the main body. A foldable main seat assembly is carried on the upper body and a second seat assembly is detachably mounted to an elongate handle by which the carriage may be pushed. The handle folds to a storage position wherein it lies along the main body. A removable canopy structure is included to overlie the main seat assembly.
