Abstract: The present disclosure provides a support device including a body interface layer resting against a user's body, a core adjacent the body interface layer with a plurality of independently acting micro coils surrounded by an enclosure layer, a stabilizing layer more rigid than the enclosure layer and the body interface layer, and an outer layer adjacent the stabilizing layer and which rests against an external surface such as a seat back when the device is in use. The body interface layer includes a curvilinear or parabolic profile with its inflection point toward a central region of the device and tapering toward lateral ends thereof. The body interface layer is thickest toward its intermediate portion which aligns with a central row of the spiral biasing devices, the body interface layer thinner outer intermediate regions aligning with outer spiral biasing device rows, providing for a consistently distributed pressure against the body.

Abstract: A method and a device are disclosed for a multi-adjustable body-rest structure suitable for use in a sitting position, including sitting positions in a multi-row seating arrangement such as those encountered on board of airplanes, busses, ferries, and trains, among other similar arrangements. The multi-adjustable body-rest structure is generally configured to be used for rest or sleep while leaning forward from the user seat onto the back of the seat in front of the user seat. The multi-adjustable body-rest structure is further configured to be folded into the back of the seat in front of the user seat when not in use. The multi-adjustable body-rest structure is further configured to be adjusted to a position that comfortably accommodates the head, chest, and arms of users with different body sizes.
