We've had these covers now for about nine months (wear and tear mattered to me when I was shopping, so for that reason I've waited to submit my review). They seem "fuzzier" than when they started, but there are no holes or thin patches (I don't know if they'll last for "years and years", but so far the durability seems decent). They take a little tucking/fidgeting to get completely neat (photo is of how they might typically look, tidied a bit but still with wrinkles). They stay in place much bet...
