A round rattan side table is easier to move around than a rectangular one and somehow feels less rigid in a room. The circular form works when you have an odd corner to fill or when you want to soften the lines of an angular sofa. Round tables have their own practical advantage which is that there are no corners sticking out to bump into. The rattan weave looks the same from all angles so the table feels intentional no matter where you position it. A round rattan side table works best in rooms that already have some flowing, curved furniture.
