The answer really depends on the camping situation wheather an air or foam mattress or a folding camp stretcher bed is the best option for a comfortable night camping.

Generally the weight and size of the mattress is the determining factor in what to choose. With streatcher beds being heavier and more difficult to transport than the air mattress which is the lightest option but unless it is self-inflating it can be difficult to inflate without access to a pump.

For the most comfortable nights sleep without a doubt use a streatcher bed with a topper foam mattess, this is a great option for camping with the kids and keeps them up off the ground which will quickly get cold and uncomfortable. You will need to be caravanning or camping from a car or trailer for this option to be practical as the camp stretchers are heavy. Ensure that the dimessions are wide enough as otherwise you can get a cold and uncomfortable metal bar in your side.

A good quality non self inflating air mattress will also provide a very comfotable nights sleep but requrires a ground sheet underliner, there are many cheaper air matresses that will still see you on the hard cold ground by morning so it really is a case of you get what you pay for in this regard. These can also get cold when the temp drops as the air inside also gets cold.

For hiking or general tent campng then a good light foam or self inflating mattress is probably the best choice and you will never have to worry about punctures or slow leaks. A ground sheet or tarp is still required as an added condensation protection and a wool blanket for added insulation goes a long way.

Keep a look out for smart designs that maximuise comfort and minimise weight, such as egg shell bubbles that keep air in indivudal pockets.

The average weight of a camping mattress is about 1.5 kgs. However, there are many different types and sizes of camping mattresses, so the weight can vary significantly. For example, a small, inflatable camping mattress might weigh as little as .5 kg, while a large, thick camping mattress could weigh up to 5kg or more.
