OSHA Ergonomics Practice Exam 2025 – Complete Exam Prep

An ergonomic chair is specifically designed to support the natural posture of the human body while seated, thereby promoting better spinal alignment and reducing the risk of discomfort or injury. These chairs often feature adjustable components, including seat height, armrests, lumbar support, and backrest angle, allowing users to customize the chair to their individual needs. This adjustability helps maintain optimal sitting posture by encouraging the hips to be slightly higher than the knees, supporting the lumbar region of the back and providing overall comfort during prolonged periods of sitting.

In contrast, standard office chairs may lack essential ergonomic features, which can lead to poor posture and discomfort over time. Wooden stools and lounge chairs usually do not provide adequate support for the back or adjustability, making them less suitable for improving sitting posture in a work environment. Choosing an ergonomic chair is essential for maintaining a healthy posture and can significantly reduce the risk of musculoskeletal problems associated with prolonged sitting.
