From what we could tell, no other bed on our list had as great a weight limit as the ACTIVE ERA QUEEN SIZE AIR MATTRESS. At 550 pounds, the rating is high enough for two people and then some. This is a particularly good thing for an air mattress, where usually if you even approach the weight limit you might start to experience air leakage.
However most camping cots have a pretty good weight limit considering that they are only built for one person. Usually this number is around 300 pounds, which should be more than enough for the sleepy adventurer.
