Elevating leg-rests and headrest extensions are necessary for these chairs.

• A. Armrests only
• B. Built-in cup holder
• C. No backrest
• D. Elevating leg-rests and headrest extensions

Answer: (D)

The need for elevating leg-rests and headrest extensions comes from the goal of supporting the body in a position that reduces strain and promotes circulation during seated use. Elevating the legs helps improve venous return and reduce swelling, which is important for comfort and long-term seating tolerance. Headrest extensions provide neck and head support, helping maintain a neutral spine and preventing awkward forward or backward postures when the patient is seated for extended periods or in a reclining position. Together, these features address both lower-extremity positioning and upper-postural support, making the chair suitable for individuals who require adjustable leg elevation and head/neck stabilization. The other options don’t supply these essential elements: an armrest-only design misses leg and neck support; a built-in cup holder is a convenience feature, not a positioning necessity; no backrest fails to offer trunk support, which is often needed alongside leg and head support.
