Couch cushions are thin, including the back cushions. They are about half the depth of my living room couch cushions. I purchased this couch for my young kids, they love it, but I do not see it lasting but a couple years. I already had to replace their previous couch from a cheap couch I purchased on Wayfair that wore out quick. If I had purchased this couch as my primary living room couch, I would have been highly disappointed. You get what you pay for though!
