Not very comfortable. The sides have a hard plastic rim that cuts into your hips when you sit. The rollers on the chair stick and makes it hard to move the chair when you are sitting on it and when your not sitting on it and just want to move it out of the way when you are cleaning.
I am very pleased with this task chair. Due to the Pandemic I've been working at home for about 9 months and just recently decided to upgrade my "work" chair. It is like night and day. The support this chair gives is incredible. Definitely would recommend it. It was easy to assemble and went together like a breeze.
Bought this as a gift to replace an older chair that was uncomfortable and getting squeaky. This one is a big improvement the headrest is a nice height and the mesh is comfier and breathable.. also our cat can't claw it up like the old one :)
