i once went to a dinner party at a restaurant with stools for seats-cafe asia dc, to be exact: 9 of the 16 guests had major back pain the following day from slumping for several hours. i can see why you would choose a backless seating option: they can be cool...but painful. if you prefer fashion over feelings, you probably love this pluto "bench" by simon pengelly, shown at neocon last week...
goes with my velcro lamp.
