Cumbria Trading Standards say that they have received a report of a black box van and its occupants cold calling West Cumbria, selling mattresses.
Trading Standards say: "If you have been approached or bought a mattress in these circumstances please get in touch with us on 0808 223 1133.
"In the case of a mattress, there are concerns that despite possibly displaying Fire Safety labels, there is no guarantee that the mattress complies with the relevant Fire Safety Regulations. They may also be of inferior quality and grossly overpriced. In addition, it is likely that statutory cancellation notices will not be given to consumers, which are required by law for most goods costing over £42.00.
