Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Researched by: Codex

Purpose and description

Enable an AI agent to recognise a pillow, assess its support and cleanliness, and decide how it may be positioned, covered, cleaned, repaired or replaced.

It can be Position or orient the pillow for its declared head or body support role.; Select a compatible removable pillowcase or protector.; Redistribute filling or adjust loft when its construction and instructions permit.; Inspect and compare support height, recovery and filling distribution.; Clean and dry the pillow using supported care instructions.; Remove from use, repair or replace it when condition and use requirements justify that action..

Distinguishing features

Check whether its declared role is local head or body support or cushioning; compressibility alone does not distinguish a pillow from a padded toy or packaging.

Check whether it is a separate, positionable support article rather than padding permanently incorporated into a mattress, seat or garment.

Check whether the item includes filling, a supporting core or an inflatable chamber; an empty removable pillowcase alone is not the pillow.

Check whether its intended role and form distinguish it from a seat cushion or bolster; record an unresolved boundary when the same article supports both descriptions.

For a contoured or specialised article, check its declared use and instructions before treating its shape as evidence of therapeutic function.

Characteristics

Intended support role
Head and neck; body; limb positioning; decorative cushioning; multiple; unknown Determines what support behaviour and placement need assessment.
Unloaded dimensions
Length, width and loft in cm, with orientation and measurement conditions Supports cover selection and comparison with the available space.
Support construction
Loose fill; single-piece core; layered core; inflatable chamber; hybrid; unknown Determines how support can change and which adjustments or repairs may be possible.
Material composition
Declared shell, filling and core materials; composition unknown where unverified Informs care compatibility and comparison with user material restrictions.
Loaded loft
cm under a recorded load, contact area and duration Describes support height during loading rather than appearance alone.
Compression recovery
Recovered loft in cm after a stated recovery interval and loading procedure Helps distinguish temporary compression from persistent loss of shape.
Filling or core condition
Even; displaced; clumped; fractured; leaking; other observed condition; unknown Identifies uneven support and material containment problems.
User and position fit
Assessed relationship to an identified user, body position and support surface Suitability depends on the intended use arrangement.
Cleanliness and dryness
Observed soiling, odour, dampness and contamination concerns, with inspection limits Guides whether use, further inspection or cleaning is appropriate.
Permitted care
Labelled washing, spot-cleaning, drying and adjustment instructions; unknown if unavailable Constrains actions that could damage the filling, core or shell.
Shell integrity
Intact; seam opening; tear; closure failure; escaping fill; unknown Determines whether the support material remains contained during use and care.

Drafted structure

Bundle to layer to finding to question, as the second pass will find it: 5 bundles · 10 layers · 10 findings · 25 questions.

Pillow identity and role Establishes what makes this article a pillow and which support role it is intended to serve.

An agent must distinguish a pillow from its cover and neighbouring padded articles before assessing suitability.

Article boundary

Identifies the complete pillow and separates it from removable accessories or surrounding furniture.

Supporting article

Records whether the item contains the supporting material or chamber and can function as the pillow itself.

  1. Does this item contain filling, a supporting core or an inflatable chamber, or is it only an empty removable cover? definition
  2. Is it a separate pillow or padding incorporated into another article? boundary

Intended support

Separates declared support purpose from appearance and current improvised use.

Declared and observed role

Records the intended body contact area, setting and any difference between declared and observed use.

  1. Which body area or decorative cushioning role is this pillow intended to serve? definition
  2. What label, product instruction or owner account establishes that intended role? provenance
  3. Does its use overlap with a seat cushion, bolster or specialised support in a way that leaves its classification unresolved? boundary
Support construction Describes how the pillow contains and arranges the material that provides cushioning.

Loose filling, shaped cores and air chambers permit different adjustments and exhibit different failures.

Fill and core

Records the internal support mechanism and the evidence for its material composition.

Internal support assembly

Identifies filling, core layers or chambers without treating visual guesses as confirmed composition.

  1. Does support come from loose fill, a shaped core, layers, air or a combination? definition
  2. Which filling and core materials are documented, and which remain unverified? provenance

Containment and access

Distinguishes the filling enclosure from covers and identifies intentional access or adjustment features.

Shell and adjustment features

Records seams, compartments, closures or valves and whether users are meant to operate them.

  1. Which shell, seams and compartments retain the filling or core, and which covering is separately removable? boundary
  2. Do the instructions permit opening, adding or removing fill, changing inserts or adjusting inflation? action
Loft and support behaviour Captures pillow shape at rest and its response to loading and repeated use.

Unloaded size and a firmness label alone cannot establish the support a pillow provides in use.

Shape under load

Records dimensions, contours and compression under stated conditions.

Effective support height

Distinguishes resting loft from the height remaining beneath a defined contact load.

  1. What are its length, width and unloaded loft, including any distinct contour heights? measurement
  2. What loft remains under the recorded load, contact area, orientation and loading duration? measurement

Recovery and distribution

Assesses whether support returns and remains distributed across the intended contact area.

Persistent support change

Records slow recovery, lasting depressions, displaced filling and other observed changes in support.

  1. How much loft returns after a stated recovery interval following the recorded loading procedure? measurement
  2. Where are persistent depressions, lumps, empty areas or damaged core regions observed? measurement
  3. Can permitted fluffing, fill redistribution or adjustment restore the intended support? action
Placement and fit Relates the pillow to its intended user, support surface, orientation and cover.

The same pillow can provide different support when the body position, underlying surface or cover changes.

Body and surface fit

Records the concrete use arrangement and evidence of acceptable support or discomfort.

Use arrangement

Identifies body contact, position and underlying surface without inferring clinical benefit.

  1. For which user, body position, contact area and underlying surface is suitability being assessed? boundary
  2. What reported comfort, instability or pressure concerns occur in that arrangement? measurement
  3. Which orientations or placements are permitted by the pillow's instructions for this use? action

Cover fit

Determines whether a separate cover encloses the pillow without unwanted distortion or obstruction.

Cover compatibility

Records dimensional fit and interference with contours, closures or adjustment features.

  1. Does the proposed cover fit the pillow's actual dimensions and contour without unintended compression or excess loose fabric? measurement
  2. Can the cover be fitted while preserving the intended orientation and access to permitted adjustment features? action
Cleanliness, care and retirement Connects observed hygiene and structural condition to supported cleaning, repair and replacement decisions.

A pillow's enclosing shell can conceal damp filling or internal damage, while unsuitable care can alter its support.

Hygiene and drying

Separates observable cleanliness from uncertain internal condition and records construction-specific care limits.

Cleaning readiness

Records soil, odour, moisture and the evidence needed to choose and complete a cleaning method.

  1. What soiling, odour or dampness is observed, and what can inspection establish about the filling or core? measurement
  2. What care label or manufacturer instructions apply separately to the pillow and any removable covering? provenance
  3. Which cleaning and drying actions are permitted, and how will readiness for reuse be assessed? action

Containment and serviceability

Assesses loss of filling containment or support and whether continued service is justified.

Repair or replace decision

Connects shell failure, air loss or unrecovered support change to a documented disposition.

  1. Are tears, seam openings, escaping fill, air loss or persistent core damage present? measurement
  2. Do available instructions support a repair or component replacement that restores containment and intended support? action
  3. Which observed condition or unmet use requirement justifies removing this pillow from use or replacing it? action

What the second pass must settle

  • How does the registry distinguish pillows from cushions, bolsters, decorative padded articles and specialised positioning supports?
  • Which repeatable loading and recovery procedures would allow meaningful comparison across loose-fill, foam, layered and inflatable pillows?
  • What evidence and assessment boundaries are required before recording suitability for infants, supervised positioning or a claimed therapeutic use?
  • How can internal dryness and contamination concerns be assessed for pillows whose filling or core cannot be inspected without damage?
  • Which construction-specific criteria support repair or replacement decisions, and how should an agent proceed when care instructions are missing?
