An ergonomic pedestal seat that interacts with the sitter's musculoskeletal system in a way that optimizes their use of gravitational forces is provided. This seat orients a sitter toward an alignment that encourages a balance between gravity's descending force and its ascending counterforce, the ground reaction force. The seat comprises a four-tier seat base, a non-vertical central supporting column and a contoured seat pan. The base has a surface that allows the sitter to sustain a stable alignment and to rock forward or sideward or both, as well as a Lazy Susan mechanism that permits turning. This seat supports the sitter through a range of seated activities, including quiet activities such as meditation and complex tasks requiring reaching, bending and turning. When on this seat sitting becomes a source of pleasure rather than an activity of drudgery.
