Inflating Types

Manually Inflated

Closely related to the air mattress a pad of this type requires an external pressure source to inflate, typically in the form of a pump or by blowing orally. Convection of the air inside the mattress reduces the amount of insulation it provides and more complicated mattresses include methods to reduce this by either partitioning the internal cavities, or by filling the cavities with material to trap the air such as down feathers or synthetic insulation. An air mattress is an inflatable mattress, usually made of plastic or textile-reinforced plastic or rubber. ... The down of birds is a layer of fine feathers found under the tougher exterior feathers. ...


Self Inflating

An extension on the conventional manually inflated mattress this type is capable of self-inflation due to the open-cell foam that fills the internal cavity. For many years this design was protected by various patents held by Cascade Designs [1] and they were an unusual and premium item. But since these patents expired many other manufacturers are now producing this type of mattress and they are now commonplace. Cascade Designs is an American company specializing in outdoor recreation products. ...


Solid Types

Closed cell foam is used to produce simple mats that do not require any inflation. Variations include textured or shaped foam to increase the unrolled volume and/or change the stiffness of the mattress. Sea foam on the beach Foam on a cappuccino Fire-retardant, foamed plastic being used as a temporary dam for firestop mortar in a cable penetration in a pulp and paper mill on Vancouver Island, British Columbia, Canada. ...
