I am a fairly heavy male and have casually shopped several months for a new office chair. I probably have sat in about 50 or so. I was not intending on making a purchase until I sat in the Staples Sorina. That was it! I purchased it on the spot.This is not only the most comfortable but it comes with a 7 year warranty. It is at least half the price of a comparable yet not as comfortable alternative.I highly recommend.
