I think the covers are pretty good.  I like the material used and think they are good quality.  The only thing I would critique is the length.  The one end folds over the top of the chair so far that the other end of the chair comes up short.  If they were about 4" longer they'd be perfect!  Either that or shorten up the pocket used to fold over the top.  I've had several people see mine on my outdoor furniture and ask where I got them.  I've referred them to Wayfair.  Since I've raved so much about them you'll probably get 4 or more people ordering the same thing.
