The chair is designed to make my back comfortable seated. The arms are in the right position. This is the first desk chair I bought in 10 years and the design is much improved over the years.
Once you get the wheels on assembly is easy. You think you have them all on lift a bit to get the last one on and another falls off. My basement floor is uneven so until I firmly tapped them in one fell of. Put a board over the leg brace above the wheel and whack it with a hammer. Chair is very comfortable and easily adjustable
