We opted for a mesh chair for our home office. Wanted the ventilation and the lighter weight. We've only had it for a month but so far seems good. We bought the extended warranty at the recommendation of the sales person who says these kind of chairs begin to have problems at the seams after a couple years.
Love it! I have used the black Hyken chair at work for the past 5 years or so. Assembly was easy for me. It's so comfortable that my colleague purchased one as well. I just purchased the red chair to use at home when I work remotely. Shipping was fast. My 16-year-old put this one together easily. Thank you Staples!
