I ordered  these covers for two swivel chairs and a sofa April of 2017.  They were outside and kept everything dry for 5 months. I stored the furniture in my basement with the covers still on and brought them out to use this year. The chair covers now leak after two months of use the lining on the inside is flaking off like dust.  They were great for one season but are now worthless.  They seemed like they were good quality but dont waste your money. The company that makes them really brags about their quality product but in my opinion it should last more then one summer.  Buyer beware!!!!
