Like a stool, a corner chair can be quite usable. It's a good way to squeeze in extra seating and fill that empty corner with something decorative. I found a few at auctions that could tempt.
This George III oak corner chair is both rustic and elegant at the same time. It's being offered at the Stair Galleries auction August 28th in Hudson, NY. It's Lot 218 and has an estimate of $400 - $600.
This wacky chair is included in the Christie's Interiors sale August 31 and September 1. I actually think it's quite interesting and would be a fun conversation piece in the corner. I'm not sure how comfortable it would be! This is Lot 484 and it's described as a 2nd half of the 19th century Rococo revival mahogany corner chair. It has an estimate of $1,500 - $2,000.
You don't see lots of them, but if you find a decorative corner chair, snap it up. Who doesn't have a corner that sits empty?
