Stuartwrote a review of ALPS Mountaineering Lightweight Series Air Pad on August 5, 2010
A bit heavy for backpacking use, but much more comfortable than my lighter weight backpacking pad as well.
We use these for car camping trips instead of the two twin sized coleman air mattress that we used to lug around. The old air mattresses required a blower to air up, a big enough space for a kingsized bed, and often left us on the ground if they got a pinhole or the night got sufficiently cold. These sleeping pads however, air up by leaving the valves open for a few minutes, then topping them off with a few puffs of air. You can overlap them if the available space demands it AND once you close the valve after topping off, we've had no trouble with deflating overnight. These also work great for when the kids have a sleepover and want to crash in the basement with their friends... :)
