The name dates the piece as much as the materials do. It was built in the long, sour hangover of the 2008 financial crisis — the same banks that caused the crash were the ones getting bailed out, and by 2010 the recovery still hadn't really arrived. The name was half pun, half hope: that the banks, and the economy tangled up with them, would spring back.
Built from two discarded Ikea bent-laminate chair leg frames — since identified by readers as the discontinued Klackbo — joined with threaded rod after Andrew discovered their existing bolt holes lined up perfectly. Onto those legs he remounted the seats and original steel springs salvaged from two antique oak banker's chairs with broken legs, using two lengths of closet rod as posts. The banker's-chair seats have a recess on their underside that locks onto the springs exactly, so the finished seat floats free with a real bounce and give.
The two banker's chairs came from the same load of salvaged wood Andrew acquired when he first moved to Los Angeles — the same load that produced the original 2008 69 Leg Table. The chair found its way onto IKEA Hackers almost by accident: a photographer shooting another piece at Andrew's loft spotted it, asked if he knew the site, and insisted they shoot it on the spot to submit. Andrew wrote up the build himself, and it ran in October 2010.
At the time, Andrew mostly saw it as a joke — and a fun thing to sit on — rather than "real" furniture; he still had an idea that furniture needed to be more formal, more considered, than a mash-up of two broken chairs bolted together. He hadn't yet come across Martino Gamper's 100 Chairs in 100 Days, which he only discovered years later. Looking back now, he sees what he was actually doing as something closer to DJing than woodworking: taking two existing, unrelated records — an Ikea leg frame, a banker's-chair seat and spring — and mixing them into a third thing that hadn't existed before, hip-hop-style, sampling furniture the way a DJ samples tracks.
