If you want to sleep comfortably on an air mattress without a cot, the first thing you need to do is make sure it is level. Using a level is the most accurate way to ensure that your air mattress is perfectly flat. Simply place the level on the surface of the mattress and adjust accordingly until it is perfectly horizontal. This will prevent any uncomfortable slopes or dips that can disrupt your sleep.1.

Another important factor in achieving a comfortable night's sleep on an air mattress is to use a flat surface. This means avoiding any areas that may have bumps, dips, or uneven terrain. If you are setting up your air mattress outside, make sure to clear away any rocks, sticks, or other debris that could cause an uneven surface. If you are using your air mattress indoors, choose a room with a smooth and level floor.2. Use a flat surface
For those who are more meticulous about their sleeping arrangements, using a measuring tape can ensure that your air mattress is perfectly level. Measure the distance from the ground to the top of your air mattress at various points to make sure it is consistent. If you notice any discrepancies, adjust accordingly until the measurements are the same.3. Use a measuring tape
A ruler can also be used to measure the distance from the ground to the top of your air mattress. This method is especially helpful if you are setting up your air mattress outdoors and do not have access to a measuring tape. Simply place the ruler against the side of the mattress and adjust until it is level with the ground.4. Use a ruler
If you want to take precision to the next level, using a carpenter's square is a great option.

A bubble level is a small tool that contains liquid and a bubble that indicates when it is perfectly level. This can be a useful tool for those who are setting up their air mattress on uneven ground.

If you are setting up your air mattress on an outdoor surface that is particularly uneven, using a piece of plywood can help create a flat and stable base. Simply place the plywood on the ground and then set your air mattress on top of it. This will help distribute your weight evenly and prevent any uncomfortable sagging.7. Use a piece of plywood
If you are in a pinch and don't have any tools or flat surfaces available, using a stack of books can work as a makeshift level. Stack the books on one side of the air mattress until it is level, and then repeat on the other side. This may not be the most precise method, but it can help in a pinch.8. Use a stack of books
Similar to using a stack of books, a stack of magazines can also work as a makeshift level. The thinner and more numerous the magazines, the more precise this method will be. Place the stack of magazines on one side of the air mattress until it is level, and then repeat on the other side.9. Use a stack of magazines
If you have extra towels lying around, they can also be used to create a level surface for your air mattress. Roll up the towels and place them under the low side of the mattress until it is level. This method may require some trial and error, but it can be effective in creating a comfortable and level sleeping surface. By using one of these methods, you can ensure that your air mattress is level and ready for a comfortable night's sleep. Remember to regularly check and adjust the level throughout your trip, as the surface may shift or settle over time. With a little bit of preparation and effort, you can enjoy all the benefits of sleeping on an air mattress without a cot.10. Use a stack of towels
