A fire label is a safety measure that is legally required to be attached to all upholstered furniture if they are sold within the UK. This includes chairs, chaise lounges, ottomans, and sofas. It is to easily identify whether the piece of furniture is in line with the British Fire Safety regulations.
The label will most likely be sewn or stapled into a cushion or on the underside of your sofa, and will give information on the fire regulations of the piece of furniture. It will also have a batch or ID number written at the top so if any problems do arise, the manufacturer will be able to trace it back.
As well as this, the fire label includes information on whether it has a fire-resistant interior and how the furniture was able to achieve regulatory compliance. They may also list the UK supplier, the date it was manufactured or imported, and a description of the materials used to make the sofa.
