I have a very unique player piano bench that I thought folks might
like to know about.  It is shaped like a standard large flat bench,
but it has a movable center portion in the hinged top which, when
rotated 180 degrees, reveals a padded, slanted player piano seat.

In other words, you can use the bench as a regular bench or as
a player bench by simply lifting up the hinged top, rotating the
center seat portion 180 degrees and putting the hinged top back down.
When the top is down it locks the center seat in place.  This is the
only one I've ever seen.  If anyone has any information on this style
of bench, I would be interested.
