The IWH mattress I use in the travel bed. She is wrapped in a kind of plastic bag with zipper. The mattress can be good three-part fold up and can be used as a seat cushion. The only temporary shortcoming, it stinks terribly after unpacking. I always leave overnight in a warm room, which must be well-aired the next day, evaporate. I am satisfied with the performance, so I buy this mattress after, although others are now cheaper.
