what do you think of this stool?

Very clever
I like the idea. I think it's even kind of funny when not being used. Might look like you have a tail. Of course, it's only really useful to sit on hard surfaces. If you tried to use it in a park, you'd sink into the grass with that small of a foot.

A tremendous amount of design has gone into dairyland over the past fifty years, making the milking stool almost obsolete, if not antique.

got, milk.
