It ends up with a big dip in the across middle of it that we had to try to fill in with pillows.
We did buy a good air mattress that helps, but I was actually just trying to give the OP an 'out'.
Here is what I have found with the sofa bed in question:
1. Be sure the fold out leg is fully extended. It doesnt extend to sleeping position on its own.
2. I didnt like that metal leg on the porcelain tile so we put a floor rug under that metal leg.
What I recall is that it wasnt level at all until I realized that leg needed to be pulled all the way to the stops. My boy sleeps on it on an air mattress.
