Shaped bodies

An ergonomic device for supporting a portion of a users anatomy comprising:

• a shaped body comprising;
• a carrier composed of at least two flexible longitudinal members;
• a plurality of transverse members, each of said transverse members being attached to each of said longitudinal members;
• said shaped body being deformable between a first position presenting a substantially flat surface to the portion of the users anatomy to be supported, and at least one other position presenting a convex surface to the portion of the users anatomy to be supported;
• a substantially non-deformable element being mountable on a frame, said non-deformable element being engaged with said shaped body such that a tractive force applied to said shaped body biases said shaped body towards the portion of the users anatomy to be supported;
• a traction cable disposed between said non-deformable element and said shaped body in a substantially transverse orientation, said traction cable being selectively tensionable between a nontensioned position and a tensioned position, and said traction cable being engaged with said shaped body such that tension applied to said traction cable applies tractive force to said shaped body to bias said shaped body towards said position presenting said convex surface to the portion of the users anatomy to be supported;
• and
• an actuator operatively engaged with said traction cable for applying said tractive force.
