I've laid on a few commercial fold-out cots and they all suck compared to a GI cot with a Camp Rest on top. The GI cot, however, is a royal PITA to put together, because it stretches the nylon canvas so tight. Not something you'd want to do daily.
For a protracted "camp-out" with vehicular access, the GI cot/Thermarest with the new GI bug net is as good as it gets.
