Had reservations about ordering the cover without seeing them in person.  To my delight, and surprise it fit perfect.  I did pay close attention to taking measurements of my sofa patio chair to ensure I purchased the closest fit.  With recent gusty winds the velcro fasteners at the legs kept the covers secured.   Thick durable plastic has protected my chairs and I ended up leaving the pads inside so I wouldn't have to store them in my garage.  Very happy with my purchase.
