add the chair shown in the reference image to the visualization place one identical chair at each table matching the design proportions materials colors finish and overall style of the reference chair position each chair so it is slightly rotated angled view rather than showing only the back side the chairs should be oriented in a way that partially reveals the table surface and the table legs creating a natural and visually open composition ensure realistic placement correct scale and proper perspective alignment with the scene do not modify anything else keep all existing furniture architecture materials lighting colors decorations dimensions proportions camera angle framing composition perspective and layout exactly as they are maintain the original image aspect ratio crop viewpoint and all spatial relationships the only change should be the addition of one reference chair per table with a slightly rotated natural viewing angle
