I have 4 bar stools that are structurally sound wrought iron but the leather seats and backs are shot.
These stools sell from $350 to $1,000 each with perfect leather.
If you are good with leather and sewing leather these might work for you.
The seats are 16" by 16". Seat height is 26".

I will consider any offer.
