I've been switching it up these most recent coupla' years, between hammocks and/or groundpads. Continually advancing age and sundry injury aftereffects apparently pose priority comfort challenges. And not only "comfort" in the cozy indulgance sense, but also in resultant functionality the next day. Seems that gravity pressing me down on relatively hard surfaces (and more so the more thin the pads) results in a distinct "achey" morn. While a hang seems to more "stretch" joints, with a different kind of "creaky" morn. Both are bothering me. Some years back, I had/used a military air mattress - rubberized thing that it was, that just may have been one of the most comfortable of all time. If I recall, it was about $50 or so, but heavy and relatively large. Yet the insulation factor was fantastic, too. What might you suggest?
