This chair is not as comfortable as the ratty, more than 17-years-old chair that it replaced, but it sure looks better!  My bet is that it WILL be as comfortable as the chair it replaced when it's 17 years old!  Our old chair could rock back and forth some, but the height was not adjustable.  I think I like the adjustable height better than the rocking back and forth, though.  (This chair does not rack back and forth).  This chair also has very good back support.

Pros: Good value for the money.  Very stable.  Adjustable height.  Good back support.
Cons: The seat is a bit on the hard side.
