I am a Retired builder and Originally I designed these for a club we built in 1979, called the Ocean Deck , Daytona Beach . In 1993,i was asked to design and build a stool that would hold up , and There still going strong . Previously to that , with the beach crowd , many different kinds were lasting a year and 2 at most.
The trade magazines will all tell you that stools without backs will do 17% more alcohol volume. In some instances it could determine whether your in the red or black.
In addition your customers do appreciate a nice padded seat.
