A suspension system with vibration isolation is described. The system can incorporate a kinematic structure comprising pairs of X-shaped supporting structures connected in parallel. The kinematic structure limits motion in the vertical direction to a single degree of freedom. Tensioning/damping of the kinematic structure orthogonally to the vertical motion limits horizontal motion of the kinematic structure with a corresponding constraint of motion of in the vertical direction. The tensioning/damping imparts passive nonlinear stiffness and nonlinear damping of the vibrational energies across the suspension system. A tuning mechanism can be incorporated enabling tension/damping adjustment to accommodate different heights and payloads. The system can provide vibration isolation at low frequencies and over a wide range of operational frequencies. The suspension system has tunable ultra-low resonant frequencies with anti-resonance characteristics. In an example application, the suspension system can be incorporated into a seat for applications experiencing whole body vibrations.
