as a suggestion, you may want to ask questions specific about hybrids on the Expandable section here.
this is a common issue with FR hybrids. other hybrid, like Starcraft, have vinyl on the bottom of their mattresses. these seem to be less vulnerable to condensation, as the FR hybrids are. but it may be that the moisture just stays inside the foam.
the FR hybrids have a fabric bottom and the heat of the humans radiates to the coolness of the bunk door. this causes moisture.
some have tried Reflectix underneath. we had some success but it didn't eliminate it.
we are trying an old wool blanket with the Reflectix. we hope this will allow some air in between and some heat reflection.
others have tried a product called Hypervent. it's used in marine applications and is expensive. they also had limited success.
