    I don’t know how you can not like this mattress. It’s so comfortable. It is much softer than our king size memory foam mattress in our room, wich is on the firmer side. But I love both. Delivered super fast couldn’t be happier.

    I haven't slept on this myself, but my parents recently visited and slept on the mattress and reported it was a big improvement over the coiled spring mattress that came with the sleeper sofa. My father, who has had back surgery and is not slight of build, reported that he couldn't "feel the bar" and had no problems overnight which was quite a change from past visits. My sleeper sofa had smaller dimensions so my choice of mattresses was limited but I am very happy with this purchase, I would certainly buy it again. I am rating this 4 starts only because I don't have first-hand experience sleeping on this item but am sure it is at least "good".

    I could sleep on this as well as on a thicker mattress -- good quality, and very little smell (so the sleeper isn't poisoning herself). On the other hand, I couldn't fold it into my sleep sofa. Too thick and unyielding? Or is this sofa bed made only for its original airbed? However, I'm keeping it, because it's much more comfortable to actually sleep on. (Storing it when not in use for sleeping.)
