1. A reversible orthopedic seat cushion comprising:
a. a right leg support channel, wherein the right leg support channel forms a convex contoured indentation, with a right lowest point line from a right rear starting point to a right front end point, wherein the right lowest point line is substantially in the middle between a right side of the cushion and a center line of the cushion, whereby the right leg support channel supports, guides, and positions the right leg of a person seated in a standard position; b. a left leg support channel, wherein the left leg support channel forms a convex contoured indentation, with a left lowest point line from a left rear starting point to a left front end point, wherein the left lowest point line is substantially in the middle between a left side of the cushion and the center line of the cushion, whereby the left leg support channel supports, guides, and positions the left leg of the person seated in the standard position;wherein the lowest point lines have outward degrees with equal absolute value, so that the shortest distance of the respective starting points to the centerline, is shorter than the shortest distance of the respective ending points to the centerline;wherein the right lowest point line has an outward degree in a range of 1 to 10 degrees, and the left lowest point line has an outward degree in a range of −10 to −1 degrees, as compared to the centerline in order to support a natural leg position when the person is seated in the standard position and in a reversed position. |
