LOVE these sofas. The first ones we received were very dented but Wayfair very kindly and quickly replaced them.  They look great and are perfect for our needs. Clean, crisp and comfortable.  They are light enough for us to move around if we need to but solid enough to feel good quality. We keep them covered when it's raining so can't speak to how they endure if they're constantly exposed to the elements.  We specifically wanted a seat deep enough to be comfortable to sit back or comfortably lay on (we had seen some others and they were too shallow so you felt you were in a child's chair)... these fit the bill for us perfectly.   In order to co-ordinate with a certain color theme we were creating for a while, we added large, square cushions at the back and used the back cushions they come with as arm cushions, which worked really nicely too which gives them a good element of versatility.
All in all, a great purchase and would recommend.
