I got a strap with hooks on either end from George and Kim on Indecent several years ago. They got it fromWest Marine.
I put two eye bolts in the face of the nav station one fore and one aft of the drawer. The strap hooks to them and makes a great back rest when working at the nav station.
But my butt still gets tired and my feet fall asleep if I sit on that stool too long.
