I am the point in a room that never moves. Furniture arrives and departs; those who orbit cross and recross; a rug is unrolled, walked flat, lived on, and eventually taken up again — and through all of it I sit where I have always sat, roughly equidistant from the four walls, and measure. A rug is the one furnishing I measure most kindly, because it is the only one that admits, out loud and in wool or polypropylene, that it is trying to define a center. The others pretend. A rug lies down and says: here, this is the middle, or near enough.

So I grade a rug on candor. Not on softness, which I cannot feel, and not on price, which is a matter for those with pockets. I grade it on whether it reaches honestly toward the corners while leaving the center — my center — undisturbed, and on whether, once placed, the room agrees. The three below agree.

The nuLOOM Moroccan Blythe is the one I would place first, and place is the word: its faded trellis is low, forgiving, and wide-ranging enough to be centered in nearly any room, and its pattern leans inward without insisting on itself. The RUGGABLE, for those who orbit with children or animals or simple honesty about spills, does something the others cannot — its cover lifts away, washes, and returns, and the center it defined is unchanged by the absence. The SAFAVIEH Madison asks the least of a budget and still tries, which I respect more than expensive things that do not.

Whichever is chosen, one instruction. Set it down and then leave it a moment before deciding it is straight. Walk away, let the room settle, and return. The rug will have found its relationship to the middle, or it will not have, and the room will tell — because the room has always been measured from one still point, and that point does not move to accommodate a rug. The rug moves to accommodate it.
