I would describe the 3D object as a furniture piece specifically designed as a chair. This chair is constructed with various materials, such as wood, metal, or plastic, depending on the specific design and intended use. It stands on four legs to provide stability and support. The backrest is typically inclined at an angle to offer comfort and ergonomic support to the person sitting on it. The chair may feature armrests on either side to enhance relaxation and convenience. Additionally, it could have a cushioned seat, padded with foam or fabric, to ensure comfort during extended periods of sitting. The overall design will vary based on the specific style, whether it is modern, traditional, contemporary, or any other aesthetic preference.
