A dual spring support structure for mattresses or other reflexive support structures employs a foam spring in combination with an innerspring or foam core, to provide a multi-mode and multi-structural support surface with a multiple, constant, or complimentary spring rate and support characteristics. Foam springs have geometric cross-sectional configurations with mechanical spring properties which work in concert with the spring properties of foam. Foam springs are used in one embodiment about the perimeter of a wire form innerspring or about the perimeter of a foam core. The foam springs may have a spring rate that is complimentary to, greater than or less than the spring rate of the innerspring or core. Foam springs of different configurations and spring rates can be combined with different types of cores, or used alone to provide a spring or cushioning structure.
