  • Multi-chamber airbed
    Patent number: 6463610
    Abstract: A multi-chamber airbed reduces the effect of weight movement by one or more persons sleeping or sitting on the airbed. In the multi-chambered airbed of the present invention, there are at least two chambers inside the airbed, each chamber having its own air valve and representing its own portion of the airbed. The chambers are completely sealed off from each other by a barrier or septum within the airbed. Thus, when one person shifts his or her weight on the portion of the airbed over one chamber, air does not flow to the other chamber or portion of the airbed.
