I have a black leatherette (not true leather) sofa that someone might like. It's modern, and the back folds down to turn into a bed (perhaps a twin, not a queen).
The only issue with it is that, as you can see in the photos, some of the finish is coming off especially in the folds. If you aren't bothered by that, or want to keep a covering on it, than it's a cool sofa / daybed.
Here is a link to some video on Facebook that shows it in action:

And here's a link to a page with more information on it... there are measurements in one of the photos.

If the posting is up, I still have it. If you write, let me know some times you are able to pick it up. It will not fit in a standard Sedan, but might in a larger SUV. I'm not sure.
(In my photos there are some swipes of discoloration, but that's only moisture from the sponge when I wiped dust off. Aside from the fabric wear you see in the photos it's in excellent shape).
