I purchased a new Ford Edge this past weekend and the buckles are so wedged down in the seat that we're really struggling to buckle my son's booster seat in. I called Ford and they have buckle extenders I can get for free. I'm assuming if it is a Ford part and, therefore crash tested with the vehicle, and it meets all other requirements (ex. doesn't put the buckle too high), that it is safe, but figured I'd better ask here first. Technically, I'm not adding an after market product.
