Air mattress

The air mattress is an inflatable mattress formed of an elastic, airtight material (PVC, natural or synthetic rubber ), which forms one or more separate cavities, so-called chambers. One or more valves are used for inflating and exhausting the mattress, usually with a blower or air pump.

In addition, a sunburn of the skin by the rays reflection of the water surface and by the refraction of water splashing occurs much faster than on land.
