My husband built us a beautiful outdoor couch for on our deck. It has 3 large seat cushions with attached back cushions. This cover fits the couch with couch cushions, 3 chaise cushions, swing cushion as well as several pillows all (lying flat on top of couch.) it is completely water proof ( we have had 2+ weeks of daily rain here in GA) and durable. The attached straps along with fabulous construction and material have kept everything dry, clean and securely attached. Ordering more patio furniture covers from this company!
