I purchased a leather sectional and matching recliner chair from Craigslist. The set looks brand new except one seat of the sectional which is a bit faded and the cushion needs a bit more stuffing. Obviously this is where the owner sat every night. Is it possible to only have the one seat refinished? Can I do it myself? If so any ideas of the cost?

I am using this set in a rec (wreck LOL) room for my kids in the basement so I don't want to spend a fortune, just want it all to look as nice.
