Can a washable-fabric symbol be copied onto a fixed sofa?
Check the finished article and care-standard scope before using a fabric label as instructions for an upholstered sofa.
A scope distinction that matters
The official ISO 3758:2023 abstract excludes non-removable upholstered-furniture covers from its scope. The standard was published in December 2023; this is a technical reference, not a new market announcement. A supplier describing a fabric as washable has not thereby approved cleaning an assembled fixed sofa.
Ask who approves the finished assembly
Our recommendation is to identify whether the cover is removable and to submit the intended fabric, backing, foam, adhesive and trim combination to the responsible furniture manufacturer. Request written instructions for that assembly. Keep unconfirmed washing temperatures and cleaning chemicals out of your sales sheet.
Make the handover usable
Record the SKU, colour, finish and approved assembly beside the instructions, together with who authorised them. If the furniture is fixed, request the appropriate cleaning method instead of inventing domestic-wash symbols.
