I've had this chair for about 3 months.  It's my work chair and I am 6'2" and weigh about 315 lbs.  it fits great, sturdy, and almost feels like a recliner.  I sit in it 6-9 hours a day M-TH and 2-4 hours on Friday.  The seat is already starting to go flat.  By Monday it's regained some of its shape but not all.  I will need a seat cushion by the end of the year.  For the price of the chair they could have used a better seat cushion.

Update 9/25/20
The chair is broken and the warranty I purchased did not cover the damage.  The chair was definitely defective.  The weld holding the threaded nut in place failed.  I'm an engineer that works in the manufacturing industry.  The experienced welders I work with all said the same thing.  The chair is rated at 401 lbs.  I weigh 287 lbs.  I use the chair for about 6 hrs a day.  All I do is sit in it.  It stays in the same spot every day.  I don't mistreat it in any way.  I will never buy anything from Wayfair again.  I'm am so disappointed.
