Had a discussion with Paul Jansen about this today and they are actually in production for a new pneumatic style bench. The old one was hydraulic and that's where they encountered some problems. The new one will operate just like the old one with a toggle to raise and lower. Supposed to be available within a couple of months. David Love davidlovepianos at comcast.net www.davidlovepianos.com
