According to some sources there about 2 billion wooden pallets in circulation and about 65% of them get used just once. It makes sense to make something out of them instead of sending them all to landfills, which in turn makes that new stuff cost less. It's a win-win situation. This here (The Pallet Armchair from Pierre Vedel) is one example of what's possible. I love seats with wide armrest so as long as this baby's sanded down to a no splinter finish, I would love one of these.
