These slipcovers are a joy compared to the heavy, stiff, canvas slipcovers I bought in the past. They fit very easily and only takes a few moments to install. The stretch of the fabric helps it snug over all the curves of the chair. I've sat in it and it doesn't seem to move much. Sure, there will likely be some retucking or we can by slipcover rods (or use a cut up pool noodle) to help it all stay in place. So far, that's not a problem. I loved these covers so much that I went ahead and even bought a second one for the other chair.
