Bought this for my music room desk. The arms folding up really help when playing guitar. The chair is very comfortable and well made. Assembly was fine; just follow the instructions and start all screws by hand for a few turns before using the included wrench to tighten them completely.
I know I put the chair together but when I went to sit it in I ended up leaning to the left side. So I put a level across the chair and sure enough it was leaning. It's very strange to sit and I'm finding myself leaning to right side while seated. Other than that the material appears that it will last for some years but I am concerned about the stitching unraveling.
Comfortable chair - should be durable. Only time will tell. Very easy assembly with great instructions. Best organized assembly instructions I ever worked with. And good warranty.
