Air mattress

Due to its buoyancy, it is also often used as a water toy or flotation device, and in some countries, including the UK and South Africa, is called a lilo ("Li-lo" being a specific trademark — derived from the phrase "lie low") or a Readybed.

Higher quality air chambers use vulcanized rubber, covered in canvas or of polyurethane with a cloth shell or tick(ing).

These hoses will be connected to an air inflation device, with two outlet valves, that will have a remote control(s) so that each person can adjust the firmness of his or her side to his/her own exact needs.

Air mattresses can also improve the quality of life (and potentially provide some measure of relief) for people who suffer with back pain.

New air mattresses can be washed in the same manner as with hygiene related issues but using hot (70 deg Celsius) instead of warm water.

[9][10] The term air mattress may also refer to a certain inflatable swimming pool or beach toy, which has an air-sac "pillow" and several (usually four or five) tubes running its length.

[12] Although it bears some resemblance to an air mattress, it is typically not built as strongly and may not reliably stay inflated all night long, making it impractical for use as a bed.
