The features that make these cot beds now unique are that they are all elevated from the ground unlike the portable air bed that you lay out on the ground when using them. One advantage of the elevated cot bed is that the bed is well above ground level, safe from getting wet in case of unexpected heavy summer downpours that some times flood the summer tents unprepared for strong rains in the summer. 

You will not have any problem of your beddings getting wet in such unexpected rains, unlike the portable double bed down on the plain ground before. In those sudden rains, you experienced having last year, you had to dry out your wet beddings hurriedly as you did not have any other set of beddings then.

This time the designers of the cots have taken care of such types of problems. Maybe the changing temperature and weather patterns dictated the redesign of the outdoor sleeping gear, knowing that rains may come unexpectedly even during the height of summer, as is happening now in many places around the globe. Many observers say that this is the first time that these unusual summer rains and storms are happening. These could be the outcome of the global warming problem now manifesting itself in many unusual storms in the off-season months.

It is of course advantageous that communication throughout the world is that easy and convenient now with all the modern media means. Happenings in remote place now spread through out the globe so fast for the information of all the people.

The way we know of the summers we had before in the previous years maybe changing now. This we will confirm in the coming three months or so.

Makers of camping equipment may be correct in the new cot beds, which are different from the previous designs and different in the materials used for their manufacture. Wood materials this time may be starting in its phase out as preferences shift to the stronger and more durable synthetic materials.

In fact, the use of wood for making many things may no longer be viable, as concern for the revival of the forests continue to grow as the only recourse to restore world temperatures to what was normal before. The disappearing forest woodlands in many countries have largely caused the occurrence of the global warming problem, now becoming more evident worldwide.        

This is the main message advocacy groups now are seriously pursuing, in an effort to rally the populations of many countries for the improvement of the environment. Many are beginning to see the seriousness of the problem; especially that food is already getting scarce, as food-production levels start to decline.
