Looking for a sleeper sofa

The sleeper sofa we now have is the inflatable bed type... by morning it's significantly deflated. I've changed it out twice with new aereo beds with the same outcome. I'm fed up with the inflatable option and I want to replace the sofa with the type that you just fold out and it's ready to sleep on. I realize that I will loose the storage space underneath but I'm more than willing to give that up.

Right now I'm looking at the trifold ones that they sell in CW.

Has anyone tried these? How do you like it?
How hard is it to take apart, put it in the trailer, etc...

Welcome your thoughts and comments.

Thanks in advance
