I have one cot, the cover is so tight, it bends the whole cot, once you made it to get the tubes in place:
Beside is another, older cot with a little "worn" cover: It´s OK to set up and it doesn´t bend the whole cot.
Have you guys any idea how to "stretch" the cover permanently? How did you do it back in your days in the military? I always need a crowbar to set up the cot to stretch the cover
