Tried and tried but could not get the back bolted to the seat without being crooked (see photo). I guess the holes were drilled incorrectly. The seat depth is a bit short for me (I'm a 5'6" woman) and the seat tilts forward so I slide out a bit and it is not as padded and comfortable as I would have liked. The lumbar support is good and I like that the back tilts and the arms are low so you can pull up to the desk. Overall, not great but you get what you pay for.
