ABSTRACT:
A floor system (20) includes a plurality of cushioning devices (22) attached to a lower side (40) of a wood floor (32). Each cushioning device (22) includes a spring (46) that may be attached at each of its ends to first and second caps (48, 50). The spring (46) includes longitudinally aligned regions (58, 60) interposed between the caps (48, 50). The region (58) exhibits a lower spring rate (64) than a spring rate (66) of the other region60. In response to an imposed force, the first region (58) of spring (46) first compresses. When the imposed force is great enough, due to a user's weight, the second region (60) of spring (46) will then compress.
