An air mattress, also known as an airbed is an inflatable mattress, usually made of plastic or textile-reinforced plastic or rubber. The deflated mattress can be rolled up or folded and carried or stored relatively easily, making air mattresses a popular choice for camping trips and for temporary bedding at home for guests. They are inflated either orally by blowing into a valve, or with a manual foot-powered or electric pump. Some are even automatically inflating (up to a certain pressure -- usually some manual work is also needed) just by opening the valve.

The three main categories for use of air mattresses are camping, temporary home use (guests) and full time permanent use (in the bedroom). Some air mattresses are specifically designed to perform both functions (camping and guest use) while others are specifically designed for one purpose alone(permanent use in the home or RV).

Lightweight, reduced-size air mattresses specifically intended for camping and backpacking are sometimes called sleeping pads, especially when a layer of foam insulation is added under the air chambers. Better quality air chambers, that are designed for permanant use in the home, are constructed of vulcanized rubber, covered in canvas or of polyurethane. These chamber(s) are then installed into a cloth shell or tic. Permanent air beds will look almost like conventional beds with the exception of having a hose (1 air chamber) or hoses (2 air chambers) coming out of the head of the bed. These hoses will be connected to an Air Inflator, with 2 outlet valves, that will have a remote controll(s) so that each person can adjust the firmness of their side to ones own exact needs. The firmness can be adjusted up or down, with the simple push of a button, on the remote(s).
