The office chair is a usual one with wheels and black, but been fixed and soldered and painted a lot for over 2 years (don't khow how long this chair was being used by the previous owner. To get the sound i just sit on it, put my phone on a tripod using the apk easy voice recorder pro by digipom, and then started moving with my feet trying for 30 minutes to get interesting sounds out of it, sometimes falling to get one continuous sound, but i never did that so my experience and technique is lacking also i dind't edit in audacity i just recorded send to email and uploaded here. The thing is that i got as a gift from a family friend and me and my dad soldered that thing probably 6 times to fix the sounds,pieces falling off, me geting in the ground after the entire base broked!( i wished i could show the picture in the center down of it) so before i went ahead to fix it again, i decided after talking to friends if i should record and upload, so here it is!. I hope is useful somehow to someone, now i can feel more at ease in repairing this chair again.
