I was just thinking about that trying to work out the hospital bed issue that wildman would need to negotiate.
I work as a nurse and I'm going through all the logistics of moving folks around in hospital beds that I do on a daily basis.
Depending on the mobility of my patient or loved one, a teardrop could work with a few modifications such as grab bars and being able to elevate mechanically the head and knee segments of the sleeping surface.
Not easy but manageable.
