+The target is a chair positioned near the center of the scene, tucked behind the low coffee table and in front of the dark sectional sofa. Visibility is limited—only the upper backrest and a sliver of the seat are seen between sofa cushions and decor items, with the rest obscured by the table and surrounding pillows. It appears compact and dark-toned, aligning in height with the sofa’s seat line, which distinguishes it from the larger sofa and the side plants that are not the target.
