If you don’t want the coffee table to be the focus of the room choose one with a glass top and a finish that blends with others in the room as in this example. This will keep the eye interested in all the items in the room not just one layer of the design. Coffee table metal bases with glass tops are another good choice to keep rooms feeling open. They’re also great when you have a special rug and don’t want to block views of it. Keep your glass cleaner handy though as there is no way around fingerprints.
For a perfectly square table you may be tempted to use four matching pieces for a perfectly symmetrical look. However you can get a more intriguing look by using two pieces or groups one in each corner. Try a tall vase or lantern in one corner with a stack of two or three books in the other (and an airy sculptural accent on top).
