A pad for supporting a thigh of a person sitting on a seat in a position that alleviates pressure applied to the lower surface of the thigh and thus for improving blood circulation through the leg without numbness or similar phenomena associated with long-time sitting. The pad is made in the form of a soft deformable body filled, e.g., with a silicone gel. The pad has a flat rectangular bottom surface and curvilinear lateral sides. In the plane perpendicular to the bottom, the pad has a triangular cross-section with heights of the triangles gradually reduced from one end face of the pad to the opposite end face of the pad so that the ridge that connects the apexes of the triangular cross-sections from one end face to the other is inclined with respect to the flat bottom.

A portable harness that wraps around the rib cage and thoracic spine is disclosed. Unlike other harnesses, the present invention has an extension allowing it to be suspended above the user's ribcage to apply an upward pull. This suspension strap provides a distracting/unloading force on the lower back by holding the upper torso in place while the weight of a patient's lower body creates traction on the lumbar spine. The harness can be used with any chair back, including office chairs, or vehicle seats. This allows people with lower back pain to sit more comfortably while sitting in a regular chair, driving a car, or flying in a plane. This will decrease low back pain since sitting for long periods will no longer compress the lumbar spine, it will actually be therapeutic by allowing a person to sit in an unloaded position.

A support comprising a first pillow having a first pillow body comprising a first arm and a second arm, a second pillow comprising a third arm and a fourth arm, the first and third arms being attached to a first joint, and the second and forth arms being attached to a second joint wherein the first and second pillows can be rotated about the joints and optionally the joints are extendable to allow the relative angle and separation of the pillows to be varied. The support provides a user with myriad options for positioning the pillows and supporting their upper body, particularly during long periods of sitting upright, such as during travel in an aircraft or bus.
