The supports (P) of the invention, where users sit, are characterized by a concave shape, with an angle (Y), in their surface area where users are in contact with their ischia (A) and ( B), and pelvis (D); in addition they include two rigid and reciprocally inclined parts or half-planes (R) and (S). They are non-deformable and bear the users' weight; they are located on the stands (O) which create convex angles (X) in their centres (E). Varying the angle (X), with a range going from (0°+1 °) to (180°-1°), according to the necessities, it is possible, in compliance with geometrical and mathematics concepts, to space out the perineum area, limited by the two ischia (A) and (B) and the genitals (G), and the centres (E) of the stands (P) of the parts (R) and (S). It is consequently possible to create a situation of wellness for users. |
