"Create an image of a modern dining chair featuring a rounded tubular metal frame. The chair should have a minimalist design with sleek, curved lines. The seat and backrest should be comfortably padded and upholstered in a fabric sleeve that is easily removable for cleaning or replacement. Show the sleeve slightly unzipped or partially removed to illustrate its functionality. The chair should be set in a stylish dining room with a wooden dining table and contemporary decor. Use neutral tones for the chair, such as gray or beige, and ensure the overall aesthetic is elegant and modern."
