We purchased these  to prevent the cats from tearing up our new cloth dining chairs. I tend to think slipcovers usually look a little sloppy, since they never fit quite right. These fit as nice as could be expected. These even fit our two taller, winged chairs (though just barely). 

Pros: Soft fabric; nicely stretch to fit chair
Cons: Wish there was a short and a tall option to accomodate chairs of various sizes
