Ergonomic thigh support and method of uniformly distributing pressure on the thigh surface of a seated person

A pad for supporting a thigh of a person sitting on a seat, said seat having a supporting surface and an edge, said pad being made in the form of an elongated body filled with a soft deformable material and comprising:

• a first substantially triangular end face, a second substantially triangular end face, and two lateral sides, at least one of which has a curvilinear shape and is intended for supporting a thigh of said person in a position raised above said edge for alleviating or eliminating contact pressure between the lower surface of the thigh and the edge of the seat;
• a bottom surface for placing onto the seat;
• a substantially triangular cross-section in any plane perpendicular to the flat bottom, including said first end face and said second end face, said triangular cross-section having an apex, a height, and sides;
• and
• a ridge that connects the apex of the first end face to the apex of the second end face;
• the height of the first substantially triangular end face greater than the height of the second substantially triangular end face so that said ridge is inclined with respect to said flat bottom.
