Ergonomic office chairs are designed to support the body comfortably during long hours of sitting. They often feature adjustable components, such as seat height, backrest angle, and armrest position, allowing users to customize the chair to their individual needs. This helps promote good posture and reduce strain on the back and neck. These chairs are commonly used in office environments where employees spend significant time at a desk. By providing proper support, ergonomic chairs can help prevent discomfort and long-term health issues, making them a popular choice for both home and workplace settings.
