upright away from the caravan walls after vacuuming. This helps aid air circulation and prevents mildew occurring, especially in units with solid ply bed bases (as opposed to slats). A further measure to keep upholstery in top condition is to cover with a breathable material such as old cotton sheets to keep the dust off. Ideally if you have room, store cushions at home in the warm, which is also a deterrent against caravan theft.
