Even though $70 is a good deal for this chair, considering how much use our computer chairs get I would suggest investing $300 into a barely used Herman Miller or full leather chair on Craigslist. They'll last for a decade or more and you can sometimes get them for even cheaper if an office is having a liquidation sale. It's a great investment and after long hours your body will thank you for it.
Yes sir Doctor!
Yeah, the cheap of today standards chairs "stink" imho.
I have a 12 plus year old cloth chair that's still alive without a tear or stitch broken/torn, can't find one that good today.
