Does anyone use a slipcover on an arm chair? We're getting the house prepared to have company a lot of the holidays and are looking at the furniture in the basement for possibilities to bring up into the living room. We have a wing chair in the basement that is like 20 years old (thanks, mom!) that is in good shape except for the cover. It's not worth re-covering because we'll eventually get a new chair and get rid of it. But I was thinking to save money and add seating, we could get a slipcover. Do they look cheap? Do they actually work? I don't want to make the room look crappy.
