Purchased this for a patio heater that I purchased from another vendor. The size is roomy and the full length zipper will make it easier to put on. The heavy duty flannel-backed vinyl is what I expected for the price. Appears to be well made and will suit my needs well. But I do expect it will not hold up for more than a couple of years in the sun here in AZ. The metal pole that several people have mentioned slips into a sleeve at the left side of the zipper and stabilizes the zipper making it easier to put the cover on the heater.
