Designing furniture for a preschool requires considering the physical dimensions and proportions of young children, which is the focus of anthropometrics—the study of human body measurements. Anthropometrics ensures that the chair and table are appropriately sized for preschool-aged children (e.g., seat height, table height) to promote comfort and safety. Biometrics (Option A) relates to biological identification (e.g., fingerprints), not furniture design. Proxemics (Option B) studies personal space and social distances, which is less critical for sizing furniture. Ergonomics (Option C) focuses on comfort and efficiency but is broader and less specific to sizing than anthropometrics, which is the primary concern for children’s furniture.

Verified Answer from Official Source:

The correct answer is verified using NCIDQ IDFX content on human factors in design.

Exact Extract:TheNCIDQ IDFX Reference Manualstates, “Anthropometrics is the most important human factor when designing furniture for specific user groups, such as children, to ensure proper sizing and proportion.”

The NCIDQ IDFX curriculum emphasizes anthropometrics as a key consideration for designing furniture that fits the user’s body, especially for specialized groups like children.

Objectives:

Apply human factors to furniture design (IDFX Objective: Human Behavior and the Designed Environment).
