They're quite annoying to setup to be honest, once you get to the last part - the back is all warped and the last 2 screws are really hard to line up.  They strip quite easily too.  No, I didn't tighten all the rest before the last two, I kept them all loose to better line things up - I'm not a novice.  

They're meh for comfort, the pads might as well be paper.  For the price though, honestly, they're fine.  They're sturdy and look good so I cant really complain outside of the setup.
