In the first place, they don't tell you which screws are which.. in the pictures, all the screws look the same, so I put the wrong screws at the bottom and the top and then had to disassemble and start again. What a waste of time! Secondly, they say that there's lumbar support. Nope. I will have to add my own lumbar support. Otherwise, it's a good looking chair. Hydralics are good, foot rest, good. Seat will also need a cushion. Thought I could tilt seat back, but nope. Seems fine if I'm sitting at my sewing machine sewing, as I'm leaning forward anyway. But if I'm sitting up high at a table to cut fabric, totally uncomfortable.
