Last year, I finally gave in to the fact that sixty years of sleeping on bad ground on a wide variety of pads just wasn’t that fun any more, and found the Helinox Lite cot at REI that weighs less than three pounds and folds into a space less than most roll-up pads. Pricey, but well worth it. Good for backpacking or airplane camping! Also gets you of the floor for when those rivers come through the tent after an afternoon thunderstorm....
