inflatable rubber mattress that is pumped full of air and is used as a bed or water floatable, airbed
For sleeping An air mattress 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.
