I bought this slip cover for my chair as well.  It makes the chair look very nice and the fabric is richer than most slip covers, however, the sofa cover is identical but does not have seperate covers for the three seat cushions.  The seat cushion on the chair is on top of the cover and holds the chair cushion in place.  When you sit on the sofa, the cover does not stay tucked in and has to be fixed each time.  I wish I could get three seperate seat covers for the couch and the sofa would look nicer and more finished.
