Investigating the paradox of bad seating postures despite good ergonomics: identifying causal factors

Abstract

This study explores the puzzling phenomenon of individuals maintaining poor posture while sitting in ergonomically designed chairs intended to promote good posture and comfort. The goal of the research is to identify the underlying causes of this paradox and provide practical recommendations for addressing the persistence of poor sitting postures in environments that adhere to sound ergonomic principles. Using a mixed-method approach, the study involves a diverse sample of participants from various industries and occupations, incorporating quantitative posture evaluations, questionnaires, qualitative interviews, and observations. The research investigates the most common poor seating postures observed in settings with well-designed ergonomic chairs and examines the psychological and behavioural factors influencing posture, including personal habits, peer influence, and workplace culture. Findings indicate that despite ergonomic interventions, certain tasks and prolonged sitting periods contribute to the adoption of poor seating postures. The study highlights the potential impacts of these postures on musculoskeletal health and overall well-being, even in environments with established ergonomic practices. This research contributes by shedding light on the intricate relationship between ergonomic chair design and seated posture behaviour, showcasing the complexity of the issue. It offers evidence-based solutions for addressing the challenges posed by poor seating postures, providing valuable insights for chair designers, employers, and individuals to promote healthier seating practices in ergonomic settings. The practical applications of this study are extensive, offering potential benefits for workplace ergonomics, posture training programs, and chair design to enhance the well-being of individuals who spend significant time sitting. By uncovering the persistence of poor postures in ergonomic environments, this study aims to advance ergonomic practices and encourage healthier seating habits for improved health and comfort.
