1. input mesh is a rounded rectangle into a bevelled extruder (a 3D box with all edges rounded)
2. add subdivision and segs on the extruder to make extra vertices for the deformers.
3. route this rounded box through a grouper to rotate/align. Pillow/Cushion needs to face -Z for the Pillow Deformer
4. facing Z, the Pillow Deformer ‘squishes’ the left, right, top , and bottom independently, along the Z axis.
5. Inflate Deformer creates the body depression
