I replaced my ergo office chair of 15+ years with this unit. I am an able-bodied 50 year old male 6'1" 190 lbs. After two weeks of daily use this piece does what it is designed to do.
Have to preface these remarks with the fact that I got this chair on sale at a significant discount. But that aside it’s attractive and well constructed and aside from the fact that the headrest has no adjustability as for height which makes it useless for me I am quite satisfied (thus far)
I bought one 3/2020 when sent home for the pandemic. It lasted 2 years of use 5 days a week and I am overweight. I am now working from home again periodically so bought another.
