I have a Harman-Karden Aeron office chair that made my legs go to sleep Also the arms would frequently release and I was constantly fighting it. This chair from Staples is great. No leg problems and I can work at the computer for hours. Well worth the price (AND much cheaper than the Aeron)!
I bought this chair to replace an aging model at home. The store didn't have it in stock but ordered for delivery the next day. After receiving the chair and assembling it I found the base was bored crooked and the chair sat at an angle. I was going to return but realized I would have to disassemble box up and reorder then reassemble when the new chair came in....."whew"...So since the base on the old chair was in great shape I swapped bases and will just discard the new one. Much less work in the long run...However this chair is comfortable and I hope will serve me as long as the last one...
