Our store, Old Plank began started in 1992, by importing country pine from Europe and in the thousands of antique pine pieces we imported, I have never run across an antique pine bench, with a back that is adjustable. You can actually move the antique pine bench back and forth, depending on how you are going to be using the pine bench. Very clever, but not sure what their original motive was? Comfortable and beautifully constructed and we believe it to be French made. **Seat height is 18.25"
