Objectification
Objectification is being treated — consensually — as an object or piece of furniture rather than a person: a human footstool, a table, a rug to walk on, an ashtray. It strips away personhood and agency for erotic effect, reducing the submissive to a thing that exists to be used or ignored. It can be purely psychological (being spoken about, not to) or physical (holding a position as furniture while the dominant uses it). The dehumanization is the point, and for many it's a profound form of submission. It overlaps with dominance, humiliation, and service.
For the submissive, being reduced to an object is a deep, freeing surrender — no choices, no agency, existing purely for another's use, which many find intensely calming and hot. For the dominant, the total control and casual 'use' of a person-as-thing is a powerful expression of power.
The submissive holds a role — on all fours as a table, still as a footstool, a body used as a seat — while the dominant treats them as that object, ignoring or 'using' them, sometimes for extended periods. Verbal objectification (referring to them as 'it') often accompanies it.
The main physical risk is holding furniture positions too long — muscles cramp, joints strain, and circulation suffers — so keep stress positions time-limited, pad hard surfaces, and check in. Emotionally, being dehumanized can hit hard, so negotiate limits, keep a safeword, and give warm, person-affirming aftercare afterward.
