The City Select LUX convertible stroller, with second seat kit, goes from a single to double, so your growing family is always ready for any adventure. It has the most riding options of any single to double stroller, with over 20 configurations. Thats over 25 percent more than City Select! Add the bench seat so your older child can hop a ride. Or, add an infant car seat, pram, or second seat to accommodate up to two children. Folding stroller is 30 percent smaller and automatically locks, so its even easier to carry. All wheel suspension and a decelerating hand brake provide increased comfort and control for this all terrain stroller.
