I just read about the Spa Sensations mattresses in that other thread here, and an idea hit me.
I have been looking for an affordable custom mattress to use in my TC to make the dinette into a sort of futon. The Spa Sensations can easily be cut down to the 68" I need, and costs a mere fraction of a custom futon mattress.
Those of you who have them, do you think the 6" mattress will stay folded 90 degrees roughly in the middle for use as a futon-style sofa cushion? Or, will it tend to want to flatten itself out, even in the face of gravity?
