Very comfortable I use as a dining table chair as I have some physical issues . Gives good support to thighs and is adjustable to fit under most dining room tables.
The seat is a good size which makes it attractive to large people especially disabled like me. Small problem. On my old office chair the back is attached behind the seat which leaves the entire dimension of the seat to sit on. When you attach the back to this chair it sits on top of the seat which takes up at least 2". If you are relatively thin this is an adequate size seat. But if you are anywhere near large or extra large it is too uncomfortable. I felt like I was sitting on the edge of something instead of on top of something. I bought 2 other large black office chairs a few years ago and still have them. On these office chairs the back is attached behind the seat which leaves the entire dimension of the seat to sit on. Neither of them have this sensation and they are not special chairs. Just meant for large people like this one is supposed to be. I am selling this one to a friend as I cannot use it.
This is a nice chair it is very comfortable makes working long hours a little easier. I bought this because my back was bothering me from my old chair. So glad I found this also came next day!!
I have only been using it for a week but it is great for me. I can't speak to assembly because my lovely co-worker assembled it for me but he said it wasn't hard.
