I CURRENTLY HAVE TWO HARMONY JUVENILE BACKLESS BOOSTERS. THEY CONSTANTLY TIP OVER WHEN MY KIDS GRASP THEM TO GET INTO THE CAR. LAST WEEK MY FRIEND'S DAUGHTER FELL OUT OF OUR PARKED CAR DUE TO THE TIPPING OF THE BOOSTER. SHE BASICALLY LANDED HEAD FIRST ON THE CEMENT! THESE BOOSTERS ARE EXTREMELY UNSTABLE! PLEASE RECALL THEM!!! *TR
