We all know, or should know, that a good nights sleep is important for your health. Typically speaking most tent camping beds leave a LOT to be desired for overweight / obese campers of which I am clearly in that range... Airbeds are typically too low to the ground, and many don't support sufficient weight limits. We also should have the decent sense to know that many people find outdoor activity a good way to help fight their struggles with weight... I have found some conflicting info, but I am going by what is on the product label. I assume there are changes over the years. I am using cots. Specifically Stansport Big Ol Cot which is an 86" x 42" sleep surface 19" high with a 600lb weight limit. The specs match, and the pics match what they are selling as the Heavy Duty GI Cot. I top it with an early 90s Therm A Rest Camp Rest, 3" self inflating sleeping pad. But still not soft enough. On top of that, I have a 6" cut to fit convoluted memory foam topper. That gives me 9" of "mattress". I wrap the mattress with an old sheet that I use these elastic sheet tensioner things that look like suspenders and then top off with my regular bedding. Sleeping bag etc... The drawback to this setup is most tents have walls that come IN very fast. We set up the cot on each side wall and set up an AC in the back wall of the tent in the summer. We have plenty of room to move around the tent, and do what we need to and be comfortable.
