I just bought a nice, trundle bed to go out on our covered, back porch. My husband is starting to enclose the porch with windows and screen, but that may take awhile. I'm worried about moisture (and critters) damaging the 2 mattresses while out there in the elements. I don't want to put the beds into storage...it's summer and we want to enjoy them. I bought some mattress pads, but they don't cover the undersides of the mattresses, just the tops and sides. Has anyone seen covers that completely enclose a mattress?

Thanks!
