The Emotional Furniture Index (EFI) is a design research framework that investigates how anthropomorphic form in furniture can evoke specific emotional responses—independent of material, color, or finish.

By isolating posture, angle, and gesture as primary variables, the project reframes furniture not as neutral infrastructure, but as an emotionally legible presence that mirrors human states such as curiosity, anxiety, or sadness.

Rather than producing a single “final” object, this work develops a repeatable system designers can use to reason about emotional impact earlier in the design process.

Furniture shapes how we sit, move, and feel—yet emotional response is rarely treated as a measurable design input.

This project began with a simple question:
If a chair can look lonely or a table can seem expectant, is it the furniture that holds these feelings, or is it us?

The inquiry builds on earlier explorations into anthropomorphism and body– object relationships, where subtle shifts in posture made otherwise ordinary objects feel expressive, unsettling, or alive.

The study begins with the human body.

A series of photographed gesture studies documented bodily positions stripped of context—slouched, compressed, extended, collapsed, balanced. These poses were not treated as performance or expression, but as structural signals: tilt, tension, asymmetry, reach, and weight distribution.

Much like furniture, the body communicates emotion through posture before any interaction occurs. A collapsed spine reads as withdrawn. An upright stance feels alert. A tilted head suggests curiosity. These cues became the foundation for translating emotional legibility into object form.

To test these ideas efficiently, I designed a modular chair system that allowed rapid recombination of form without fabricating entirely new objects.

This resulted in 16 total configurations, enabling controlled variation of posture, balance, and gesture across a consistent structural baseline.

Participants categorized each chair across eight emotional states. Responses were aggregated to identify patterns linking specific formal cues to dominant emotional readings.

Several strong trends emerged:
Several strong trends emerged:
Upward or tilted backrests were consistently read as curious or playful
Downward or drooping forms reliably evoked sadness
Leg angles exceeding ~15° from vertical triggered anxiety due to perceived instability
Direction of a curve mattered more than magnitude
Emotional valence followed orientation, not intensity

Despite a limited sample size, these reactions appeared across cultural backgrounds, suggesting baseline human tendencies rather than purely stylistic interpretation.

Rather than prescribing outcomes, the index functions as a design lens— helping designers move from vague intent (“make it feel welcoming”) to concrete decisions (“soften the backrest tilt” or “reduce leg divergence”).

This framework allows emotional intent to be considered alongside ergonomics, rather than after the fact.

Three chairs were developed as proof-of-concept outcomes—Curious / Playful, Sad, and Anxious—each translating a distinct emotional state into structure. These pieces are not endpoints, but physical arguments: demonstrations of how abstract emotional intent can be made legible through form using the Emotional Furniture Index.
By separating emotional impact from ergonomics, the EFI reframes furniture as an expressive medium ratherthan neutral infrastructure. The framework enables more intentional emotional design, reduces trial-and-error in early prototyping, and supports stronger emotional attachment to objects— encouraging longevity and care.
This work continues to inform my ongoing explorations in anthropomorphic furniture, material experimentation, and body–object relationships.
