An immobile siobhan sounds like an *extremely* frustrated and bored one....

Some massage people have massage chairs as well as tables, which resemble a cantalievered contraption with a ring-shaped pillow at the top. One sits facing the pillow, and rests one's face in the opening of the ring, giving support it a mostly-vertical position. Getting up from teh chair can be done with mostly arm and leg strength if one is careful, so this option may be an option while you're undergoing your (hopefully speedy, but not speedy enough) recovery.
