We love this chair...I've has 2 of them (one for me and one for my wife) for the longest time and they are both in excellent condition...no sag in any of the spots that provide support. I liked it so much that when I needed a chair for my work bench area I ordered another one.
As comfy at home all day as it was in the showroom testing it for only 10 seconds! Big improvement over my last faux -leather chair; my back no longer hurts and i'm comfortable all day
The chair is very comfortable and sitting all day to work in it does not cause any discomfort. Only think would be nice is if the head rest part of the chair could go higher.
Easy to put together. Lots of adjustable parts (chair moves up and down tilts forwards and back arm rests go up and down lumbar support and head rest move). Typical mesh desk chair.
