Abstract
Cushion backed carpet tiles and carpet tile installations which can be installed without adhesives are described. The carpet tiles are manufactured according to rigid specifications in order that no corner of any of the individual tiles is {fraction (1/16)}″ or greater off the floor due to curl, and no corner on the tile has cup of greater than {fraction (3/16)}″. In this way, a substantially to entirely adhesive-free carpet tile installation can be achieved, with the installation being capable of withstanding the rigors of a variety of typical types of wear, such as rolling traffic, etc., without shifting or snowplowing over adjacent tiles.
