Another CL chair re-done
This one must weigh 40 lbs, just the frame, but I was attracted to it when I saw it, and I hadn't even seen its distant cousin at Restoration Hardware. Oh, the RH one is now on sale for $1440, down from $1695...Link below
Anyway, mine was $45 and a LOT of elbow grease, but I'm pleased with the result. I cut the curve from the bottom of the back, as I preferred it without. The frame is 2"+ thick oak.
