I love this slipcover - it fits like a glove.  The foam inserts that are supposed to keep it in place are worthless, but you really don't need them anyways.  The cover doesn't shift much, and when you get up, it's quite easy to just straighten out the cover where you were sitting.  If I could give this one more stars, I would (speaking as someone who has purchased SEVERAL failed slipcovers this year).
