This thing is very tiny for its weight. The memory foam is hard and dense (even with days to recover), and the airbag inside (about like a freezer bag with a blow-up) does nothing for comfort. I returned it--the ThermaRest brand pillows filled with "recycled scraps" from the self-inflating pads are far more comfortable.
