Only took an hour to put together. Would have been easier if I'd had someone else to help hold the back and seat while positioning them but I managed. All the parts were there and all screws and holes lined up properly. The instructions were clear (I would have added 2 small steps or pictures to make it even clearer). Sits up nice and high. My old desk chair did not go as high as this one and I had to use a cushion. It's also nice and big. I've only sat it in for 2 days now but I like it.
Purchased this for my husband who works from home. It is comfortable enough to keep the day pleasant but you won't fall asleep in it. 360 rotation height lever sturdy armrests and back support. Bought the black chair. Paid for staples to put it together for us. So far so good. Would recommend or even bought an additional chair if I needed it.
