Abstract: A modular flooring assembly, includes at least two floor members, each including top and bottom portions, and edge portions configured for operative engagement with the edge portion of an adjacent floor member to form a common joint, wherein the engaged edge portions are further configured for facilitating radial movement of the juxtaposed floor members about the common joint, a resilient, elastic material supporting the bottom portion of the floor members in contact with the ground, and an attachment system including clip with a cross-piece member having first and second ends, a pair of opposed legs, each extending from the corresponding first and second ends inwardly toward one another, and the legs each configured for operatively engaging the top portions of corresponding one of adjacent floor members to securely retain the engaged floor members in juxtaposition and prevent lateral separation, while permitting radial movement of the adjacent floor members about their common joint.
