Multiple ply managed friction material surface with smooth bonded seams

A substantially smooth managed friction material surface for preventing abrasion or decubitus ulcers in a living being, said managed friction material surface comprising:

• a plurality of plies, each ply having a smooth side;
• a first frictional zone;
• a second frictional zone;
• at least one adhesive ply interposed partially between adjacent plies;
• and
• wherein the plurality of plies are selectively bonded at the adhesive ply to form a first frictional zone of higher friction and wherein the plurality of plies remain unbonded proximate the first frictional zone to form a second frictional zone of lower friction and wherein the adjacent plies are allowed to move substantially freely with respect to one another in the second frictional zone of lower friction.

An apparatus for placement on a support surface between the support surface and a living being, the living being having a bony prominence, the apparatus comprising:

• a substantially smooth and seamless material surface having:
• a bonded zone, the bonded zone having a high coefficient of friction, the bonded zone configured for positioning remote the bony prominence;
• and
• an unbonded zone adjacent the bonded zone, the unbonded zone having a low coefficient, the unbonded zone configured for positioning proximate the bony prominence;
• and
• wherein the bonded zone and the unbonded zone occupy different areas on the same side of the material surface and wherein no seam exists on the material surface between the adjacent zones.
