Abstract
An adjustable orthopedic support pillow which includes a contoured top layer, a plurality of supporting layers, each having tongue-and-groove structures to enable the contoured layer to be removably supported by one or more additional supporting layers.
Claims3
An adjustable neck support pillow comprising:
- a first layer having a first, contoured surface and a second surface having at least one cavity extending along a length dimension of the first layer;
- and
- a second layer having a first surface having at least one projection that fittingly and removably engages the at least one cavity of the first layer and having a second surface having at least one cavity extending along a length dimension of the second layer.
An adjustable neck support pillow comprising:
- a first layer having a first, contoured surface and a second surface having at least one cavity extending along a length dimension of the first layer;
- and
- a second layer having a first surface having at least one projection that fittingly and removably engages the at least one cavity of the first layer;
- a second surface on said second layer, said second surface opposite said first surface of said second layer;
- and
- at least one lower layer, where each of the second and lower layers have opposite surfaces and combinations of conduits or projections on either said opposite surface.
