Specifications for a mass producible static lounge chair for the elderly

Area of Science:

• Ergonomics and Human Factors
• Geriatric Care Design
• Rehabilitation Engineering

Background:

• Designing furniture for the elderly requires specific considerations for comfort, safety, and accessibility.
• Existing lounge chairs may not adequately meet the unique needs of individuals in long-term care or rehabilitation settings.

Purpose of the Study:

• To develop and refine the design of a static lounge chair specifically for elderly users.
• To enhance user comfort, posture, safety, and ease of ingress/egress through iterative design modifications.

Main Methods:

• Utilized an adjustable seating rig to create and modify chair prototypes.
• Recruited elderly subjects from long-term care and rehabilitation wards for testing.
• Employed questionnaires and video analysis to evaluate user experience and chair performance.
• Iteratively refined the chair design through four distinct testing phases.

Main Results:

• Identified key design parameters influencing comfort, posture, safety, and ease of use in elderly individuals.
• Successfully modified the chair's shape based on empirical user feedback.
• Developed a final chair design with optimized contours and specifications.

Conclusions:

• The iterative design process, incorporating direct user feedback, is effective in creating specialized furniture for the elderly.
• The final lounge chair design addresses critical needs for comfort, safety, and accessibility in geriatric care.
• The study provides valuable insights and specifications for the development of supportive seating for older adults.
