Easy assembly. Very comfortable chair with almost all the features/functions of significantly more expensive chairs. I wish I could change the tilt of the seat, but otherwise, I have all the adjustments I need. Good value -- and great value when it was on sale for ~40% off.
The only issue was a major one. The back seat would not come up enough. Sitting in the chair felt like I had no back support because the back part would not come up to meet me.
The chair was easy to assemble, though quite heavy. But it may be the single most uncomfortable chair i have ever sat in, and its lowest setting jams my legs against the desk. the lumbar is not great-the support is there, if you like what feels like a steel bar rammed into your spine, even though it is padded, it just juts very far forward. unfortunately i have to disassemble (I assume) and return it.
The first chair I got had a broken locking mechanism. The back would not stay locked in one of the 3 positions. After speaking with support, they sent me a whole new chair as a warranty replacement. The second one works properly. I love all the adjustments, and the lumbar support is great. The one annoying thing is the arms rotate just by moving them and I am constantly moving them unintentionally. Other than that, I love the chair.
This is a great chair. It was not hard to put together and its is very comfortable. I like how adjustable it is, the arm rest height and lower back suppordt can be moved. If I want to lean back I don't have to fight to keep it back. I recommended this chair to family who have office jobs because of how comfortable it is.
