UV and Sunlight Management
Full-grain leather fades under sustained UV exposure — the dye in aniline leathers is particularly vulnerable. For high-floor south or west-facing apartments, choose a semi-aniline or pigmented leather with UV-resistant finish, or position the sofa perpendicular to the window wall rather than facing it. Fabric sofas: solution-dyed fabrics (where colour is applied in the fibre production process, not surface-printed) have significantly better UV resistance than surface-dyed fabrics. If in doubt, request a fabric sample and leave it on a south-facing windowsill for 2 weeks — solution-dyed fabric shows minimal fading; surface-dyed shows visible colour shift.
