Softer and smoother shapes give your living room a more comfortable and laid-back energy, while still providing useful storage and surface space in a choice of styles and materials.
You can use a round coffee table to add some softer lines and more organic edges to your living room. Round tables can also help to add more space in cramped living rooms, creating more open areas where corners would be.
There is no set size for a coffee table. They should be as big or small as the space dictates. You need it to be big enough to have practical value but not so big that it takes up too much space or dominates your living room.
It depends on the size of your coffee table and the overall style of your living space. If you have taken a minimalist approach, you might want to keep your table surfaces clean. But you can also decorate your coffee table with a selection of reference books, candles and other ornamental pieces.
