ThatDailyDeal has this Self Inflating Inflatable Lounger for as low as $13.99 w/ FREE shipping (Reg. $59.99) when you buy 2 or more. As a price comparison, this item is currently selling for $25-$40 on Amazon.
Once filled with air, simply roll the top of the Hangout and clip it shut, effectively turning it into a comfy lounger that you can sit on and lie down on. It can handle weights of up to 350 pounds, so up to 2-3 people can comfortably plop down and kick back in comfort. A recessed center area is designed to cradle anyone who lies down on the lounger, making the darn thing feel like a non-swaying hammock. It stays at a good rate of inflation for around four hours under normal use, at which point, you simply unclip the top and feed it a gallop of air to restore the fluffy, bouncy shape. Construction is durable ripstop nylon so it should handle most anything on the ground, short of large, sharp rocks.
