The seat cover is a little boring but I planned from the purchase to recover and you should too.  It is so much easier than you think it is.  A yard of fabric will easily cover two chairs so you should go crazy and buy a super expensive fabric.  A staple gun and a screw driver to reseat the seat and you are done.  Do it.  

Pros: Good value, easy assembly and reassembly (which isn't always true)
Cons: boring fabric - who cares!  See above.
