I got a great deal on this chair and it is very comfortable. It was delivered quickly easy to build with simple instructions and tools and feels sturdy. The height adjustment works fluidly as well. Very happy with the purchase.
I paid for assembly due to my disability so paid more than I wanted to. The chair is nice but after sitting only 15 minutes in it my tailbone and rump started to hurt. After 45 minutes I had to get up because it really hurt. I will have to buy a seat cushion for it but the size is perfect for me. It is a sturdy chair too bad the seat isn't cushioned well.
