When leather fibres have weakened, an immediate softer feel is not evidence of restored strength. Flexing and excessive conditioning can make cracks larger.
Warning signs
- Fine crackling or powdering under very gentle pressure.
- Cracks extending at flex points.
- Separation between the leather and its backing.
- Colour or surface material coming away when touched.
Next steps
- Reduce flexing and loading.
- Provide appropriate support and a dry environment.
- Restrict intervention to controlled professional assessment.
- Prioritise preservation over cosmetic renewal.
Instant softness is an unsuitable acceptance target. For collectible or sentimental items, stable preservation can matter more than forcing a return to use.
