Nice firm cushion and backrest. Someone else said there was no backrest tilt - and to some extent they are correct. The tilt is included on the backrest and allows a sufficient amount of tilt (without needing a whole tilt mechanism). If you are looking for a chair to tilt back and slouch in, this is not it. If you are looking for a chair that is ergonomic but allows you to lean back a little, this chair is perfect.This chair almost forces you to sit up straight (which I like). The footrest is perfect for my garage workbench, and the arm rests are sufficient. I do wish the arm rests were a little wider on the surface area, but they do provide adequate support. At first i thought they forgot to include the screws for both the bottom plate and the arm rests, but soon realized the screws were already inside the bottom of the chair. You have to unscrew them to use them for mounting. Also, as others have stated, there is no mention of how to install the foot rest, but it's pretty easy to figure out.* You can also look at the box of extension parts to see a diagram of how to install, but otherwise, here you go: *1) After assembling the bottom legs/casters, put item C (the black pipe with openings on both ends) into the center hole.2) Install the ring and push down to seat it into item C.3) Then place the hydraulic system into the ring with the clear/white button facing upwards.3) Install the plastic sleeve mechanism with the big opening towards the bottom.4) Place your assembled seat/back/armrest on top.I attempted to cancel this order prior to it shipping, but it ended up shipping anyway. I was going to return it, but decided to see how it felt before I did. After assembling it and trying it out - I already love it too much to send it back. It really feels like a quality ergonomic chair for $115 - and definitely worth it in my opinion!
