An office chair is designed to provide comfort, support, and proper posture during long hours of work or study. It typically features an ergonomic design with adjustable seat height, a supportive backrest, and armrests that help reduce strain on the neck, shoulders, and lower back. Many office chairs include breathable materials for all-day comfort, smooth-rolling wheels for easy movement, and a sturdy base for stability. Suitable for home offices, workplaces, or study rooms, an office chair helps improve productivity while promoting healthy sitting habits.
