I am hoping someone can give me the measurement from the top center of the seat hoop to the center of the rear most tube of the frame. When I put the plastic seat bucket in firmly on the front and sides of the seat frame the rear of the plastic seat bucket is a few inches away from the seat hoop at the top. If my hoop is right it would be like a rocking chair.
Thanks in advance

Kerry,
I have 2. One measures 17 1/8” and the other is 17 1/4”

Thank you. Mine measures 15". I knew something was off.
