All of the ES pull-out sofa beds I've encountered have either been full size (~54") or queen size (rarely). So it should be big enough for the mattress. However, it might not be strong enough or provide enough support for a regular mattress.

Have you considered bringing an air mattress and pump? I've done this when traveling with younger children and it works very well.
