Air beds are also known as blow up mattresses and are commonly used for camping as they are convenient and easy to carry. A lot of these air beds come with foot pumps but can be blown up in minutes with an electric pump. Air beds are also great for visiting guests.
Water beds are just that - beds filled with water! There are two types of water bed, soft sided water bed or hard sided water bed. The more expensive water beds are made to lessen the wave effect which was common in the early models. Water beds are usually heated and a thermostat controls the temperature.
