Abstract: A car seat/stroller has a rigid tubular telescoping handle assembly and wheel bracket assembly which are fitted thereto in a manner which does not interfere with normal operation of the device as a car safety seat, but rather enhances the seat's safety and convenience. The handle assembly consists of a series of telescoping sections of tubing. Two holes are drilled at a diagonal angle into an infant car seat at respective top corners of the seat's sides, and further through respective flares at armrest portions of the seat. A tubular sleeve is inserted into each hole and is fed through to an underside of the flare. A clamping adjustment device is then affixed to one or both tubular sleeves at an upper portion thereof. Tubular L-shaped upper handle members are inserted into the tubular sleeves.
