You (maybe?) get what you pay for! These covers are pretty flimsy and cheap, even considering how inexpensive they are relative to other cushion covers.  One of the seat cushions came with a broken zipper and was ripped at the seam and has to be exchanged.  I'm hoping I get a year or possibly 2 out of them, because this is one of the few covers I could find that would fit my slightly larger-than-normal cushions that didn't cost as much as just buying a new patio set.  They look decent, but time will tell how they actually hold up.
