The Boulevard ClickTight Convertible Car Seat with Cool Flow features an innovative fabric and provides stylish safety. At Britax, we’re making safety cool – your child will enjoy a comfortable ride thanks to our Cool Flow technology. The ventilated mesh fabric improves air flow and the padded seat and head rest ensures added comfort, along with the 7-position recline. Car seat installation is easy as buckling a seatbelt thanks to the ClickTight Installation System. In the Boulevard Car Seat you are surrounded in safety. This convertible seat features the patented Britax SafeCell Impact Protection system which includes a steel frame, energy-absorbing base, V-shaped tether to minimize seat rotation and staged-release stitches that slow and reduce forward movement in the event of a crash.
