If you wake up in a pool of sweat it could be that you’re showing the first symptoms of some bizarre tropical disease, but unless you have red spots all over it’s more likely that you’ve discovered a naugahide-a-bed.

Especially in the budget and backpacker price ranges hoteliers sometimes try to protect their mattresses from spills, absorbed odors, sweat and other bodily fluids even more discomforting to consider by covering them with something impermeable.

Some use fake leather upholstery fabrics like naugahyde, others have plastic backed mattress pads and some simply leave the mattress in the plastic bag that it arrived from the store in.
