I've used the futon mattress for a few weeks now, it works perfectly as a couch and it's very comfortable as a bed. It fits 2 adults comfortably. I love the density not too hard and not too soft. It's a little heavy for my cheap futon frame, but a bit of muscle power still works. I seen reviews for the odor and yes it has a slight odor from packaging but it dissipates within a couple days.
