One size doesn't exactly fit all.  I ordered one each for Sofa, Loveseat, a chair and ottoman.  The Sofa and loveseat covers seem to be exactly the same size.  It's a little loose on the loveseat and very tight on the sofa.  They are nice enough I'm using them in a family room so the fact they they look a little off is ok.  If I was going to use them in a more public area of my house I'd look for something that fits better.
