Before buying, I compared the posted measurements to the dimensions of our couch, and it seemed like the slipcover would fit okay, but in reality it's way too small. Possibly an error on my part, but maybe there could be better fit-finding instructions before purchase. Our couch has 3 cushions and the arms are kind of thick. Probably better for 2-cushion sofas. I can get the cover to fit nicely around the sides and front; half of the back of the couch is exposed though. Still, luckily, this is alright for this couch because it's against a wall. I would have returned it otherwise. Dark denim blue is so pretty and looks so luxe.
