While some users perfect to use them with their existing mattress, air mattress, or camping cot, there are some minimalist campers that forgo these things all together to be able to pack as lightly as possible. If you plan on using these items on your next camping trip without a cot, we suggest ensuring that they come with a base. Then you can simply set up your sleeping bag, pillow, and blankets directly on the ground. You might not be as warm as you would if you were propped up off of the ground, but it will be an excellent way to keep the bugs, weather, and moisture off of you while you sleep.
