The kids have outgrown their cots and mine is reaching the sagging/stretched out phase so about time to pick up 4 new ones. This is for car camping so don’t need to be ultra light, but don’t want them taking up all the space in the back when hauling them. The largest person is me at 6’2”, 200 lbs. any recommendations for something comfortable that won’t be stretched out after a week of use? No air mattresses.
