We have not had guests sleep on the mattress yet. It doesn’t look like it would be comfortable though, so I am buying a foam topper.
However, it is a very nice piece for the price. I like that it is all wood including what the mattress sits on. Personally, I would not have it in my living room, but in a small bedroom it is perfect. 
Also, the directions to assemble were amazing! Color coded, if you mess it up it would be because you didn’t pay attention to the color coding. This was the easiest piece of furniture I’ve ever put together! The only thing that takes 2 people is lifting the 
couch onto the base.
