Hard to complain for the price. Arm rests are a little wobbly Headrest is reasonably adjustable. I really like that the back doesn't only recline but also locks in place in multiple positions. Shipping was unbelievably fast.
It's not comfortable as in you can sleep in it it just makes ur back hurt less after sitting in a chair all day. If the armrests were more adjustable (horizontally) i'd have no reason to upgrade.
Easy to assemble. Seems well built no issues so far. Adjustable comfortable and cool. Good value for money spent. Best cheap chair I have owned. It won't be mistaken for a high end chair but still nice.
