ABSTRACT In different sectors of industry, sedentary employment frequently results in physical discomfort and pain, which lowers productivity. With the purpose of reducing pain and enhancing wellbeing, a modified palliative chair is suggested. The chair offers support for the lower back, neck, and shoulders and incorporates on demand massage and heat treatment elements. The research on the health advantages of massage and heat therapy is discussed, emphasizing their potential to lessen the adverse consequences of extended sitting. The adopted design may increase productivity and well-being, which would be advantageous to both employers and employees. To completely comprehend the effectiveness and user satisfaction of this technology, more research is required. Employees can improve their physical well-being while at work with the help of this updated ergonomic chair design. KEYWORDS: Sedentary employment, Ergonomic chair design, Massage therapy, Heat treatment, Productivity, Workplace well-being. INTRODUCTION Sitting for extended periods of time is becoming common in fields such as information technology, higher education, and management positions. This can result in physical discomfort and suffering, which in turn lowers productivity. While designed to support and comfort workers during long shifts, ergonomic chairs may not always be able to fully alleviate the pain and discomfort brought on by prolonged sitting. In response, we suggest a modified palliative chair with features for on demand heat therapy and massage to reduce pain and enhance physical well-being. This review paper examines how the suggested modified palliative chair design can help sedentary workers. We will go over the research on the health advantages of massage and heat therapy, emphasising how they might lessen the impacts of prolonged sitting. We will also look at the difficulties and restrictions that come with using this technology, such as the price, technical needs, and user preferences. This redesigned ergonomic chair design has the potential to increase productivity and well-being, benefiting both individuals and employers, by offering an affordable option for professionals to improve their physical well-being while at work. Other fields that necessitate extended sitting, such call centers and financial institutions, may benefit from the proposed design. To completely comprehend the effectiveness and user satisfaction of this technology, more research is required. LITERATURE SURVEY In their study, Mohanty et al [1] provide a comprehensive approach that combines statistics and artificial intelligence to create industrial or office workspaces that consider the physical and psychological needs of employees, resulting in greater effectiveness and production. They use measurements from the Bureau of Indian Standards to conduct a case study on office chair design to evaluate their methodology. The authors discover that creating items with the best criteria can increase customer attractiveness while minimizing user weariness and damage. Workplace settings can be created to encourage productivity and well-being by considering the physical and psychological demands of employees. According to Samad [2], ergonomics is becoming increasingly crucial in boosting efficiency, safety, and comfort in industrial production as technology progresses. Ergonomics seeks to optimize the interaction between people, tools, and the workplace, which includes designing tools and equipment to match the worker's demands and tailoring the environment to the worker's requirements. Backaches, neck pain, and muscle strains caused by inadequate seating and posture are major concerns in ergonomics. This can be addressed by creating pleasant and user-friendly workplaces, giving workers with ideal surroundings, lowering physical workload, and optimizing working postures. Chandra et al [3], highlights how the advancement of information technology has resulted in the establishment of "office ergonomics," which entails creating desks, workplaces, and workstations that may be utilised by different persons at different times. This includes examining corporate operations and creating workstations with furniture, equipment, computer systems, and environmental
aspects in mind. Overexertion and repetitive strain injuries at work underscore the need for a better understanding of workplace ergonomics and workstation design, especially in flexible office employment. The paper includes an in-depth examination of these problems, as well as the development of flexible office design to reduce negative consequences and boost good ones, while also emphasising worker health and safety and analyzing the critical ergonomic challenges in office work. The COVID-19 epidemic has raised demand for ergonomic computer workstation chairs, as more individuals work from home using computers. According to Math et al [4], the global market for these chairs is predicted to reach $ 29.67 billion. In response to this desire, the authors created an ergonomic office chair for laptop users using Indian anthropometric data and Solid Works, with the purpose of decreasing muscular tension and increasing productivity. A CAD model of the workstation's parts was created using design inputs derived from common human traits. This project focuses on laptop users, who have fewer ergonomic design requirements than desktop users. Xu et al [5] emphasize the relevance of employing ergonomic principles to analyze human sitting position and dynamic behaviour in current office work. To produce new design concepts for office chairs that are pleasant, productive, and safe for human health, extensive research is required. Modern office chairs should be constructed with the body's posture in mind to reduce negative health impacts while also promoting comfort and productivity. The authors recommend that while designing ergonomic workplace chairs, numerous elements be considered, including human posture and interactions between people and seats. The authors illustrate how to develop safe and comfortable workplace chairs by using design examples that combine ergonomics concepts. By taking these factors into consideration, ergonomic office chairs can increase workplace efficiency while decreasing the risk of musculoskeletal issues. Employees must sit in a supported and comfortable position in office chairs because many modern western jobs require them. A study was done by Roland Zemp et al [6] to evaluate the precision of objective methods for calculating sitting comfort. They discovered a relationship between users' perceived levels of comfort or discomfort and office chair pressure measures, suggesting that pressure readings may provide some insight into how comfortable users are. To completely comprehend the connection between objective metrics and unique sitting comfort experiences, more investigation is necessary. The study stresses how important it is to evaluate office chair ergonomics and design from both an objective and subjective standpoint. In their overview of international ergonomics regulations and recommendations for designing computer workstations, E.H.C. Woo et al [7] note the variations and their effects on health issues. To address the accelerating development of computer technology and its effects on computer users' health and wellbeing, they offer arguments and suggestions for modifications to the current standards and guidelines. The best practises for input devices, visual displays, lighting, environmental factors, and furniture arrangement and design are suggested in the article. The authors stress the significance of upholding current ergonomics norms and recommendations in order to reduce the risk of health problems
