These chair covers are wonderful.  We live in Fountain Hills, Arizona.  These chairs covers are in the hot Arizona sun almost all day long, they hold up the best that we have ever used.  I formally would purchase covers from a large well known retail store here in Fountain Hills, they would last for not more then one summer and they would be tearing apart.  These covers last 2- 3 years in this intense heat.  Very pleased with your product and would highly recommend them.  Your customer service and shipping free is the best.
