ABSTRACT:
A rocker provides complex rocking motion by virtue of a volume-compressible foam section sandwiched between two substantially rigid upper and lower plate sections. The upper plate, volume-compressible foam, and lower plate sections are secured to form a single integral unit that provides complex relative motion between the upper and lower sections, which motion exhibits pitch and roll characteristics about a vertical axis through the center of gravity of the rocker when occupied.
