Update: I received an open box instead of a new chair (items were not packaged in original bags, some were packaged  in garbage bags). I decided to keep the chair because Wayfair was offering me discount on the item. a month later I found that the chair is sinking - probably a damaged cylinder.. Wayfair sent me a replacement part which I just received today - when I opened the package I found ROCKS instead of a new cylinder for a chair. NO WORDS.

I just finished installing the chair. The adjustable armrest and headrest are most - would be able to use the chair without it. Overall good product for 150CAD but if price would go up there would be better options out there.
