Before purchasing a coffee table for your living room, you need first to determine its shape. The proper shape depends on the user’s needs and taste, but also depends on the size of the sofa and on the seating configuration.
The arrangement of the seating area: The sofas, the armchairs, the rug, the coffee table, the end tables, any ottomans, etc form an assembly of independent pieces that moreover should work as a group. For example, when seating furniture is placed face-to-face then a rectangular or oval table is probably the best choice for this configuration. When two sofas of the same length are placed in L-shaped arrangement, then a square or round table is an advantageous choice. If the furniture placement is done in the round, then a round coffee table compliments the arrangement.
The linear arrangement of the seating furniture in U-shape dictates a rectangular coffee table.
