I bought one of these for me a couple of months ago and every time I left my desk I would come back to it with someone else using my chair. I have a small office so maybe this addition will let me have my chair back. I would recommend this chair.
It's pretty comfortable to use for extended periods of time. I like the mesh design for the ventilation to stay feeling cooler - no back sweat one can get with a solid back and seat.
Chair is of good quality! However if your big person would recommend a different chair. I’m only 6ft and weigh 210 and the chair is not the best fit for someone my size or larger!
