The couch itself is nice, quite firm, but still comfy. I like that I can fully stretch out across the length. The main reason I bought this couch was the additional section that you can clip into the couch to make the sofa bed. It’s perfect because it creates an extra seating area, or foot rest or even a coffee table, and the storage is perfect for keeping the pillows and duvet for guests. 
My only downside was putting it together, it was not easy. It seems easy on paper.. but physically not easy, especially if you’re on your own. Plus the marking for the clip section that you’re meant to screw in don’t have pilot holes, so I needed to drill those myself. And the instructions were in French... 
But after all is said and done I’m happy with the couch!
