Product is very well made...heavy fabric and seems quite durable.  I have two tub-style chairs and these fit fine.  Since they are brand-new, I haven't experienced how they will withstand the winter months but based on the heaviness and texture of the fabric, I am confident my patio chairs will withstand the snow and cold weather.  They've already been rained on and the furniture stayed nice and dry.  I like the Velcro ties for the legs.  So far I'm very happy with this purchase.
