The mattress itself is comfortable when laid out, but in couch form, it’s not. The part you sit on isn’t deep enough to sit comfortably as you have to sit up dead straight. Even then, you can’t sit too close to the edge because the edges haven’t been reinforced, so they “collapse” down under your weight and you slip off . We’ve set it up without the back up, and have it essentially folded in half to use as a lounging area, and it’s comfortable that way! I think it’s a good product but needs some work to make it more comfortable as a sofa as it’s intended.
