A coffee table for a sectional sofa should complement both the style and layout of the room. Ideally, it should be around two-thirds the length of the sofa and low enough to be comfortably reached from each seat. Consider a round or oval table for an open, accessible look, or a square or rectangular shape to match right-angled sectionals. Ensure there’s about 18 inches of space between the table and sofa to allow for easy movement. A lightweight table on casters is perfect if you plan to rearrange often.
