Abstract
An article that is suitable for use in surface coverings, such as laminate floorings, wherein the article has at least one interlocking edge of a first profile and at least one interlocking edge of a second profile. The interlocking edges provide the ability to interlock adjacent articles without the need for an adhesive, and yet form a substantially gapless seam between the articles. The articles may be joined and unjoined from each other a plurality of times without any substantial deterioration of the interlocking edge profiles.
