Solid tabletops usually have a very square corner. If you have little kids or the circulation is tight allow extra space at the ends so it’s easier to get around the corners without hitting your shins. Go for color with an upholstered coffee table as it will draw people to the surrounding sofas and chairs. Top it with a tray to hold books and other items (and to soften a strong color such as the pink).
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).
