What needs to be clarified
Measure the mattress profile after an agreed unloaded recovery period and distinguish observed residual deformation from base effects, cover behaviour and features of the particular mattress construction.
Materials to prepare
- Mattress with model label and accessible bed base
- Instructions on suitable support and use
- Timed indentation photographs and mattress-rotation records
What to compare
Describe support, slat arrangement, fixings and cover condition. Record the profile at specified points, stating conditioning and measurement method. Where technically feasible, compare the actual base with a suitable flat support. Specify height-loss or hardness testing separately after checking construction applicability and preserving the initial inspection records.
Possible outcome of the analysis
The result may include a profile diagram and opinion on a measurable indentation under stated conditions, support influence and further testing needed to assess internal mattress layers.
Limits of the conclusions
Perceived softness is not measured height loss. Without baseline data, change timing cannot be pinpointed; opening the cover or undocumented transport may alter the features being examined.
