Almost four fifths of an inch thick, this build suits a dedicated lifting corner rather than a whole room. Twelve tiles of 24 by 24 inches cover 48 square feet, enough for a rack footprint plus working space, and 24 borders close the edge. The rubber wear layer sits on high-density foam and the two are fused through an adhesive-infused bond, so the tile stays intact when a loaded bar comes down on it. Extra depth means more impact absorbed and less noise reaching the rest of the house. Scissors trim the outer pieces to fit against skirting, and the 30.5-pound set moves one tile at a time.
