Purpose and description
Enable an AI agent to recognise a mattress, assess its support, fit and condition, and determine suitable placement, use, care or retirement.
A mattress is a resilient pad or assembly designed to support the body during sleep or rest, used on a bed base or another suitable supporting surface.
It can be Check measured fit and documented compatibility with a proposed bed or foundation.; Compare support and comfort evidence while preserving test conditions and subjective preferences.; Inspect for persistent sagging, edge collapse, leaks, dampness and cover damage.; Orient, rotate, flip or adjust the mattress when its construction and instructions permit.; Choose a permitted cleaning, drying, storage or transport action.; Determine whether documented condition supports continued use, further inspection, repair or retirement..
Distinguishing features
Provides the main cushioned body-support surface for sleeping or reclining, rather than a thin accessory placed over another mattress.
Contains an identifiable support body, such as resilient material, springs or fluid chambers, rather than functioning only as a sheet, blanket or protective cover.
Is distinguishable from the frame or foundation that supports it, even when supplied together as a bed set.
Is intended to support a reclining body across a sleeping area; a seat cushion or pillow has a different primary support role.
May be removable, rollable, inflatable or integrated into convertible furniture; permanence and rectangular shape alone do not determine whether it is a mattress.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 32 questions.
Sleeping role and boundary Establishes what counts as the mattress and the sleeping setting it is intended to serve.
Mattresses are easily confused with toppers, bed assemblies and specialised support products whose requirements differ.
Primary support role
Identifies the component that supplies the main cushioned sleeping support.
Mattress versus accessory
Record whether the item is the primary sleeping support or an accessory that depends on a separate mattress.
- Does this item provide the main cushioned sleeping support, or is it intended to modify another mattress? boundary
- Which covers, pads and support components are integrated into the mattress, and which are separate accessories? boundary
Intended sleeping setting
Captures the declared environment and users without inferring suitability from appearance.
Declared use envelope
Record intended settings, occupant constraints and any evidence needed before treating a specialised mattress as suitable.
- What manufacturer information identifies the intended sleeping setting and user group? provenance
- Which proposed uses fall outside that declaration or require separate suitability assessment? boundary
Support construction and response Describes how the mattress supports a reclining body and how its response can be assessed.
Mattresses with similar dimensions can behave differently because of their cores, layer arrangements and adjustment mechanisms.
Core and sleeping faces
Records the load-bearing construction and the arrangement of usable surfaces.
Support layer arrangement
Identify the support core, comfort layers, edge construction and designated sleeping faces from available evidence.
- What evidence identifies the core materials, comfort layers and edge-support construction? provenance
- Which face and head-to-foot orientation are intended for sleeping, and is the mattress reversible? definition
Loaded surface behaviour
Separates measured support behaviour from subjective comfort descriptions.
Support response evidence
Record firmness, recovery, edge compression and motion transfer with their assessment methods and mattress settings.
- Under what load, foundation, temperature and test method was firmness or indentation assessed? measurement
- What observations distinguish whole-surface compression, local pressure response, edge collapse and movement transferred from another sleeper? measurement
- If support is adjustable, which settings may be changed and how is the resulting support state checked? action
Bed fit and installation Connects mattress geometry and flexibility to the supporting bed and installation constraints.
A nominal size match does not establish safe fit, adequate underlying support or compatibility with articulation.
Sleeping surface geometry
Captures actual dimensions, shape and relevant gaps after placement.
Measured fit
Assess the mattress against the receiving bed or enclosure using measured dimensions and applicable fit instructions.
- What are the mattress length, width, thickness and shape after any specified expansion period? measurement
- What gaps or height changes result when it is placed in the intended frame, enclosure or convertible furniture? measurement
Foundation and articulation
Identifies support and bending conditions the mattress is designed to tolerate.
Permitted underlying support
Record required foundation characteristics and any constraints on bending, folding or unsupported spans.
- Which foundation types, slat spacing and centre-support arrangements are permitted by the mattress instructions? provenance
- May this mattress bend with an adjustable base or fold for transport, and what documented restrictions apply? action
Sleep-surface safety and hygiene Captures use-specific safety evidence, cover integrity and conditions affecting hygienic use.
A mattress has prolonged body contact and may contain safety-relevant internal layers that cleaning or damage can affect.
Safety evidence and cover integrity
Associates safety claims with the intended use and assesses damage to enclosing layers.
Documented safety basis
Record applicable safety evidence and cover-handling restrictions without treating labels as proof of suitability for every setting.
- Which safety requirements or certifications are documented, by which issuing body, for which market and intended use? provenance
- Does the cover enclose a fire barrier or other internal material, and do the instructions permit its removal or washing? action
- Are tears, failed seams or exposed internal components present that require further assessment before use? measurement
Moisture and contamination
Distinguishes visible surface conditions from uncertain contamination within the mattress.
Cleanability and drying
Record contamination evidence, permitted cleaning methods and uncertainty about moisture or contamination inside the core.
- What evidence shows dampness, staining, odour, suspected mould or suspected pests, and does it indicate possible penetration beyond the cover? measurement
- Which cleaning and drying methods are permitted for this cover and core construction? action
- What evidence is needed before the cleaned mattress can return to use? action
Wear, care and retirement Links mattress-specific deterioration to permitted maintenance and end-of-use decisions.
Surface appearance alone may conceal support loss, while age alone does not establish the state of a particular mattress.
Support deterioration
Assesses persistent deformation and failures within the support body.
Loss-of-support indicators
Record lasting depressions, uneven response, displaced filling, damaged springs or chamber leakage under stated inspection conditions.
- What depressions or uneven areas remain after unloading for a recorded recovery interval on a suitable foundation? measurement
- Is the observed support problem attributable to the mattress, its adjustment state or the foundation beneath it? boundary
Permitted care and exit
Connects construction and condition to handling, repair and retirement choices.
Condition-based next action
Choose the next action using observed condition and documented limits on rotation, flipping, repair, storage and disposal.
- Do the sleeping-face design and instructions permit rotation, flipping, chamber repair or replacement of a removable cover? action
- Which observed defects or unresolved contamination concerns require repair, specialist assessment or retirement? action
- Which local reuse or recycling routes accept this mattress construction and condition? action
