was super easy to assemble other than getting the wheels one which seemed to need a bit of a trick to get on -- wiggle them in so that the clip goes in at an angle Comfort level is good for this kind of chair
It's a very comfy chair. The arms give me much needed support now that I'm working from home sitting at a desk all day long. ((Not sure why I got sent 2 different items to review that I didn't buy though...))
Assembly was fairly uncomplicated. But the reason for 4 stars is that it is not as comfortable as the one tried in the store. Had to add a pad to the seat and pads to the plastic arms.
