computer chair back to life

My computer chair was on its last legs so I Frankensteined it back to life!

This is my computer chair that I've had for many years. It's getting gross and the cushion is all flat so I've been on the lookout for a new one.
Found this for $7 at Goodwill. Score!
After using the new chair, I realized the old chair had MUCH better wheels. The new chair's wheels felt like they'd scuff up my floor pretty badly eventually, so I thought I'd just swap the seats. New cushion, mesh back, nice wheels – what could go wrong?
Of course, the bolt holes are in different places. I thought about swapping out the cylinders, but they are different sizes. Then it hit me!
Swap out the support boards!
I brought a heavy-duty staple remover home from work to help with this. It broke after one staple so I did the rest with a tiny jewelers screwdriver and a pair of vice grips. 3 hours and 5,000 staples later…
Attached the new cushion to the old support board with lots of staples and voila!
My perfect chair!
