Best Answer

Self inflating camping mattresses are filled with open cell foam. Open cell means the air in the bubbles is not permanently trapped but can be pushed in and out of the bubbles. This foam is made from a flexible and durable plastic with a strong "memory" so that it tries to return to the same shape after pressure is removed.

When the mattresses air vents are opened on a deflated mattress, the pressure of the foam trying to revert to its expanded shape pulls air in to the mattress. The vents are then closed and the trapped air inside the mattress provides support for people lying on the mattress.

How does a self inflating camp mattress inflate itself?

The self-inflating ones are inflated by opening a valve which leads to an air bag that has a piece of foam inside it. With the open valve, the foam is able to suck air into itself so it can go back to its normal size. Air is also sucked into the other areas of the air bag. When the valve is close and you lay on the mattress, the air tries to escape the foam but it can't. This makes it just like an air mattress or sleeping on foam. To deflate it you open the valve and start rolling it up from the other end. This squashes the foam and all the air can escape through the open valve.

How to Inflate an Air Mattress?

Inflating an Air MattressAn air mattress is a convenience around any home. It makes a perfect bed for visiting guests, a comfortable place to sleep while going out camping or a great daybed for naps with young children. Understanding the methods of inflating the air mattress is necessary to make it as comfortable as possible.Start the process of inflating the mattress by laying it out on the floor. The mattress should not be rolled up or folded while filling it with air. Instead, unfold or unroll it until it lays flat. The mattress top should face upward while the bottom faces down. Usually, the valve for air is on the bottom or one side of the mattress.Pull the cap off the air valve. Most air mattresses will require twisting the cap off. Once the cap is off, attach the pump. Depending on the pump, the method will vary. Some slip inside the valve while others cover the valve on the outside. Flip the on switch to start pumping air into the mattress. If the pump is manual, it will require hand or foot pumping instead of having an electric switch to turn it on.Allow the mattress to fill completely with air. Feel the firmness and let out some air until it is a comfortable softness or firmness for personal preferences. Twist the cap back onto the mattress valve to prevent air from escaping. The mattress is ready for blankets, pillows and sleeping on once the cap is back in place.
