I always rate instructions first when reviewing products.  The instructions for this chair definitely need some help!  The hardware was hard to decipher and the diagrams took some time to understand.  Getting the pieces to fit together and get the screws to go in properly was nearly impossible.  The Allen wrench provided could not be used to get the screws in.  A power screwdriver was definitely needed and we’re still not sure they’re in right.  Putting the chair together leaves a lot to be desired.  The style is pretty simple and suitable for many different people.  The back is a little low but not terrible.  Just wish it were a little higher.  Overall the comfort is fine.  Mechanisms to move the seat work ok, nothing difficult.  Overall, kind of disappointed in this chair simply because of the instructions and building it being difficult.
