Purpose and description
Enable an agent to recognise a couch, assess its suitability and condition, and decide how it may be placed, used, cleaned, moved or repaired.
A couch is a seating furniture item designed to accommodate two or more people on an extended seat, usually upholstered and fitted with a backrest, with or without armrests.
It can be Assess whether the seating geometry and documented capacity suit an intended use.; Check room placement, delivery access and clearance for reclining or bed deployment.; Arrange and connect sectional modules according to documented compatible layouts.; Operate reclining or sleeping features when their condition and instructions support the action.; Select cleaning, cushion maintenance or upholstery repair from component-specific evidence.; Identify damaged seating positions and plan supported disassembly, repair or removal..
Distinguishing features
Presents a shared seating body with back support intended for sitting or lounging; nominal seat count alone does not settle the boundary.
Uses seat and back cushioning or upholstery as central features of the provisionally intended domestic furniture sense, unlike a typical plain bench.
A sectional forms a couch through modules intended to function together; adjacent independent chairs do not become a couch merely through placement.
A convertible couch has an intended seating configuration as well as a sleeping configuration; a bed with pillows is not sufficient evidence.
Clinical positioning features or a specialist treatment purpose trigger a sense-boundary review rather than automatic inclusion.
Scope
+ Shared seating form, back support and intended sitting or lounging use
+ Seat geometry, overall dimensions and room-access requirements
+ Frames, suspension, cushions, upholstery and their relationships
+ Sectional connections and optional reclining or sleeping mechanisms

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 30 questions.
Couch identity and configuration Establishes the intended couch sense and the seating assembly being described.
The word couch can name different furniture forms, while sectionals blur the boundary between one couch and several pieces.
Seating kind boundary
Distinguishes the domestic couch from neighbouring seating and specialist furniture.
Domestic couch recognition
Record intended use and physical form as evidence for inclusion rather than relying on the product name alone.
- What combination of shared seating, back support and cushioning identifies this as a couch? definition
- Does its primary function place it with domestic couches, benches, chairs, daybeds or clinical furniture? boundary
Sectional assembly
Describes the modules and orientation that constitute a couch configuration.
Module membership and handedness
Record connected sections, corner or chaise positions and the viewpoint used to describe left and right.
- Which modules belong to this couch, and which connections are intended to hold them together? boundary
- Which layouts and orientations are supported by the module instructions? provenance
Seating fit and placement Relates the couch's usable seating and changing footprint to occupants and the room.
Overall couch size alone cannot establish sitting suitability or clearance for extended features.
Occupant fit
Captures usable seat geometry and supported occupancy claims.
Usable seating geometry
Measure the space and support available to a seated person with the relevant cushions in place.
- What are the usable seat width, depth and height, and were they measured loaded or unloaded? measurement
- What evidence supports the stated occupant count or load rating, including its per-seat or total basis? provenance
- Does the intended user need a practical assessment of reaching the back support and standing from the seat? action
Room and access fit
Accounts for placement, conversion space and transport through room access points.
Placement and delivery envelope
Distinguish assembled dimensions, moving-part clearance and the dimensions of permitted transport pieces.
- What space does the couch occupy when seated, fully reclined or converted for sleeping? measurement
- Which parts may be removed for delivery, and what access envelope does each remaining piece require? action
Seat support and upholstery Records the construction that carries occupants and creates the couch's contact surfaces.
Similar-looking couches can differ in support, cushion behaviour and repair options.
Frame and suspension
Describes the load-bearing frame, seat support and sectional load connections.
Seating load path
Identify documented or observable support components while distinguishing concealed construction from verified facts.
- What evidence identifies the frame, joints and seat suspension beneath each seating position? provenance
- Where are looseness, sagging, uneven support or damaged module connections observed? measurement
Cushions and coverings
Separates cushions, filling, upholstery panels and removable covers.
Cushion and cover map
Associate each cushion and covering with its position, materials and permitted removal or rotation.
- Which seat and back cushions are fixed, removable, reversible or position-specific? definition
- Which labels or specifications establish the filling and covering materials for each component? provenance
Reclining and sleeping functions Covers optional mechanisms that alter the couch's posture or use.
Convertible couches require configuration-specific assessment; absent mechanisms should be recorded as not applicable.
Recliner operation
Captures manual or powered adjustment, controls and movement constraints.
Recliner state and clearance
Record moving sections, actuation method and observed condition before recommending adjustment.
- Which seats recline, how are they actuated, and what power source is fitted if any? definition
- What instructions govern clearance, obstruction checks and returning the mechanism to its stowed position? action
Sleeping conversion
Describes how a seating assembly becomes a supported sleeping surface.
Bed deployment and support
Record the conversion sequence, deployed supports and the resulting sleeping surface.
- What sleeping-surface dimensions and load limits are documented for the deployed configuration? measurement
- Which supports, locks or cushions must be positioned before the sleeping surface can be used? action
Couch care and serviceability Connects upholstery care and seating defects to supported maintenance and repair decisions.
A couch may remain visually presentable while its support fails, and unsuitable cleaning can damage its covering or filling.
Upholstery care
Establishes component-specific cleaning instructions and unresolved contamination.
Supported cleaning method
Use care evidence for the actual upholstery and filling instead of inferring a method from appearance.
- Which cleaning methods are supported by the couch's labels or manufacturer instructions? provenance
- Do spills, odours or suspected contamination extend into filling or concealed areas requiring further assessment? action
Seating defects and repair
Relates local defects to continued use, repair access and replacement components.
Use and repair decision
Record affected seating positions and the evidence needed to support use or a specific repair.
- Do observed frame damage, unstable supports, exposed components or mechanism faults require an affected position to be taken out of use? action
- Which cushions, covers, connectors or support components can be replaced, and what establishes replacement compatibility? provenance
- What product-specific safety or conformity documentation exists, and which couch configuration does it cover? provenance
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

- Which of these neighbouring kinds and how to tell them apart hold for the sense of couch this model covers, and on what evidence? provenance
What the second pass must settle
- Does the registry intend couch to mean domestic sofa-style furniture only, and does an existing sofa world model already own this concept?
- Where should inclusion boundaries fall for unupholstered couches, single-person chaise longues, daybeds and specialist therapy couches?
- Which measurement conventions should govern compressible seat geometry, sectional handedness and delivery envelopes?
- Which safety standards and labelling requirements apply across intended jurisdictions and domestic, commercial, reclining or sleeping uses?
- What evidence is sufficient to assess continued use after frame, suspension or conversion-mechanism damage, particularly when manufacturer information is unavailable?
