Chair is great and is well suited to a LARGE bottom & WIDE hips.  
My only complaint:  The height of the backrest can be adjusted but it ratchets up until you hit the highest level then releases back to the lowest point.  It's the way it's meant to work but if you want it at the highest point it seems to always drop back down if you wiggle around while sitting.  I'm going to fix it in the highest position with a screw for a semi-permanent position.  Other people have put a block at the base of the seatback once it's at the right height which would be good solution if you prefer to keep it easily adjustable.
