Seen and tested at George Taylor Specialties
in Tribeca, this Lyon Industrial stool
(no longer available as of 9/2013 - sorry!) is remarkably light and stable with a stylingly industrial look. We can easily see having these in a NY kitchen in grey or painted a special color (a la Martha Stewart).
They can be found at C & H Distributors for about $50 each, but you should be sure to also order the rubber feet which make them soft on the floor. The feet can be seen on their Diesel stools here.
We pulled a bunch of pics below because the site is hard to navigate!
