Looking around in Northern Tool today, came up on an aisle with TRACTOR seats--thas' rite---Tractor seats. Durable quality HD vinyl covers, no seams to split, w/ folding or rigid seatbacks. Some were high backrests. Plastic or metal frames, pretty good selection of styles in several colors, http://www.northerntool.com

Not flashy but if you need some basic durable inexpensive seating for your resto, these might work. $89-$229 per each.

Jus' tryin' to help a brotha' out!
