The photo, the drawing and description of Amazon are wrong! In the photo you can see the underside of the seat. The seat should have been mounted rotated to take pictures 180 degrees. Then you would see that is folded, the seat when not in use upwards (unlike in the description) Even with the drawing of the mistake was made. I bought and installed the seat. The accompanying description shows the correct mounting of the seat. The quality of the seat is very good, the dowels and screws are long enough. (5 stars) I just wonder when Amazon changes the error.
