We bought this chair for the pair desk in our office its used by mainly 2 part time employees one person is rather large and we were worried it wouldn't be comfortable to him but he says if very comfy.
I sat in it at the store and played with the adjustments. It was on sale and compared to the other chairs on the floor it was the one for me. I like it even better after I got it home. I adjusted it for me personally and it makes a huge difference in how I feel after working all day at my desk.
The seat is firm yet comfortable for sitting all day. I am 5’3” and have trouble finding desk chairs that fit me and my desk. The adjustable arms make it on this one make this the perfect chair. Great purchase!
