We purchased this cover to cover our newly purchased outdoor chairs for the GREAT CANADIAN WINTER we suffer through here in our home city of Pickering ON.  Although the snow has not arrived yet our chairs are securely covered and are safe in advance of the snow fall. Right now we are experiencing cold and wet weather and on several days I have checked the covers for any leakage and possible cracking.  Much to my delight neither has occurred. The cover remains in place despite some high winds that have come our way.  The cover is very durable and the price is also very reasonable.  I highly recommend this cover for your chairs.
