Terrible. The measurements are not real. I measured my couch and it was 1 inch shorter on all measurements except 1. That measurement was the same as the description. Meaning this cover should fit. It didn't come close. In fact, I was only able to fit 2 cushions into the slot for 3. And the bottom piece intended to cover the whole couch stopped halfway down the back. In addition to bad measurements, the quality is also janky: At some point, the elastic cushion cover string popped as i was trying to heave the third cushion into the 2 inch leftover space. 
DO NOT BUY -- unless you have a love seat. 
And Boo this product and its description writer.
