Unfortunately this chair was not for my body type. I got it as a recommendation from a friend. I am 6 feet tall and 145 lb I have no cushion on my backside. The seat of the chair has not supported it is just mesh netting it hurt my legs when I wore shorts and very uncomfortable for my tail. I thought ergonomic would be the way to go but I am returning this chair unfortunately. I also did not like the arms they barely adjust in height.
If you have any weight to you (plump folks) the bottom seat portion is MOLDED plastic and MESH. Not a good foundation for support for long term sitting. Because if your parts don't fit in the uncurved section you will sit uneven and it's very uncomfortable. Otherwise I LOVE this chair. Will buy another if I can get a cushier seat. It actually makes me very tired at the end of the day. Assembly was easy peasy.
