1. A work platform, comprising:
a generally planar top member having a surface sized to receive a user's feet thereon while standing; and a bottom member disposed below and coupled to the top member, the bottom member having an outer edge that defines a width and length generally equal to or larger than a width and length of the top member, the bottom member having a bottom surface with a curved surface generally at a longitudinal center of the work platform defined at least partially by a radius of curvature of between about 100 mm and about 850 mm, the bottom surface including a generally planar surface at two longitudinal ends of the bottom member, a convex surface defined by the curved surface and a concave surface interposed between the planar surface and the convex surface, a front side edge and a rear side edge of the bottom member defined in a widthwise direction of the bottom member on opposite sides of the curved surface at a location that is laterally inward of the outer edge of the bottom member and vertically spaced from the outer edge of the bottom member by a distance configured to limit a tip angle in a widthwise direction of the work platform to thereby limit a heel-to-toe rocking motion of the work platform and inhibit overstretching of a user's calf muscles during use of the work platform, wherein the curved surface is configured to induce instability under a user standing on the top member to thereby facilitate active muscle engagement in the user's legs while standing on the work platform. |
