These fit my chairs perfectly for storing them outside during our snowy winter! I found online these blow up "pillows" to put up against the back of the chair so the snow didn't sit there on the cover and keep piling up. Good for the chairs and good for the cover. Good quality material  and the tie downs were easy! My chairs are not rockers per se, but more like gliders. I measured them and these covers fit great. Wayfair had had so many things I've looked for at fair prices!!
