If you don't sit in or recline these, they're perfect.  It's one of those things that does the job in covering nasty fabric or leather, and is great for an occasional chair that isn't used often.  If you do use the seating often, be prepared to re-adjust when you leave the chair.  They are pretty much working for me.  I had bonded leather chairs in my movie room that turned into a disaster when wet bottoms sat on them.  We have 8 chairs, only 2 are used all the time.  I got a nice look in our movie room when I added these slip covers, and I only really adjust 2 of the chairs often.  I will agree with another reviewer in that there seemed to be a lot of material in some places, and little in others, but I was able to make it work.
