Abstract
A rocking chair comprises a base portion and a seat portion and includes a pair of C-springs for coupling the base portion to the seat portion. The C-springs flex to provide the seat portion with a desirably smooth and soft rocking motion while providing excellent structural integrity. Each C-spring has a contoured cross-sectional profile that provides a spring stiffness adapted to provide a smooth and comfortable rocking motion for a wide variety of body weight. The contoured cross-sectional profile also provides a high torsional resistance for minimizing lateral rocking movement of the seat portion.
