Have had many chairs over the years mostly low-cost task type chairs. This chair has many adjustments and is not oversized. Initial comfort testing was good comparing to the "Pedic" brand instores I preferred this one. Long term I am not super confident the mesh will last for more than a few years but the price was not too bad. I use this with a desk elliptical (Elipse) without issue. Doesnt hurt my tailbone like my kneeling chair did.
