My daughter loves the song 'All about the base' - listen to the great version below. I'm not sure how appropriate it is as she is only ten but it is a good description of the Back App - well almost as the seat is pretty special as well.
The Back App base is not so big as the one in the song. At 600mm across is similar to most office chairs but like the song this base can move! You get a core muscle exercise from using it.
