We are selling a Britax Pinnacle ClickTight Combination Harness-2-Booster Car Seat that our child has outgrown. This car seat expires on April 1, 2024. It comes from a smoke-free and pet-free home. The car seat has very high weight and height limits. It features side impact protection cushions and a foam headrest. The headrest and harness adjust simply by pulling up or down. It can be reclined while the seat is in harness mode. We have found this car seat/booster to be very EASY to install. In harness mode, it can be used with children who weigh between 25 and 90 pounds and are between 30 and 58 inches in height. In booster mode, it can be used with children who weigh between 40 and 120 pounds and whose height is between 45 and 62 inches. The user guide fits nicely in the car seat itself so it is always close at hand when needed.
