If it's a choice between carrying an inflatable pillow that weighs almost nothing, takes about three breaths to inflate, rolls to the size of a jumbo gherkin, and is comfortable to lay on... Or unravelling your neatly packed inner tube, pumping about fifty times with a mini pump, stuffing it in a bag, then spending ages squeezing all the air out and trying to neatly and tightly re-roll it again every morning... I'll take my inflatable pillow. :)
