I agree with the general comment that the sofa isn't immensely comfortable - but also agree that no past
DVC sofa with a convertible bed inside has ever been comfortable. Comparing the old to the new Murphy sofas, I actually prefer the new Murphys. As a sofa, they're a bit hard...fine for when I'm sitting upright, wanting to chat or eating or on my computer - when trying to lean or lay a bit more casual for watching TV or a movie, they're a bit too hard - but I just grab some of the extra pillows from the bedroom and use those to soften where I want.
With the old pull out sofa bed couches, I hated how much I sunk down into them, to the point where the hard outer edge dug into the back of my knees - I had to stick the throw pillows under the couch cushions so I didn't sink down so far.
And as a bed, of course, the new Murphys are a significant advantage over any previous fold-out designs. Even the best, most recent pullouts, which were relatively flat platforms once extended, still squeaked and groaned getting out, and had super-thin mattresses that always required egg-crate cushions to make them tolerable, then they were difficult to fold back up with the egg-crates in place...and storing cushions all around the room when the bed was out made the entire living room basically unusable when the bed was out. With the murphy down, you can still move around the room, use the chairs, use the balcony, etc very easily.
