Not necessarily. A padded item can retain moisture within filling or thick areas after the surface changes. Its own care instructions determine the appropriate drying process.
Understanding this situation
The dryer must support the item's construction and bulk. An ordinary garment programme is not automatically suitable for a duvet simply because the door closes.
A useful next step
Check the bedding maker's guidance and the model's permitted programme before use. Follow the specified method for assessing and finishing the item. If suitability cannot be established, choose an appropriate alternative rather than repeatedly heating an oversized load.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
