Replacement 60" Jackknife Sofa without Arms
Does anyone know where to find a 60" jackknife sofa without arms? I am looking to replace the original one that serves as the bottom bunk in the rear slide area of my Sunseeker 3170DS. It's basically affixed directly to the slide-out floor, and, when converted to bed mode, lies flush with with a side cushion that extends the sleeping surface area.
This seems to be a non-standard size. All the ones i've found online without arms are 62", 68", 70", 72". But the space available for the sofa is exactly 60". I was wondering if perhaps this is actually a 68" sofa without the arms, assuming that the arms are 4" apiece?
Any ideas, suggestions?
