An inflatable positioner includes a low coefficent of friction (COF) on a top surface and a high COF on a bottom surface. The inflatable positioner is slid under the patient and then inflated by an air pump. At least two positioners can be inflated and deflated with the air pump and a timer. A non-inflatable positioner may be inserted into a positioner bag with a high COF outer surface. An inflatable gusseted or non-gusseted positioner may be created from a single sheet of material or from two sheets of material. A tail may be attached to a positioner to allow thereof to be pulled under a patients body. A strap may be attached to the positioner to allow the positioner to be secured to another object. The sheet of material may be breathable or non-breathable. A plurality of breathable vent perforations are formed through the non-breathable sheet of material.
