At Harrison Spinks, we don’t add any fire retardant chemicals to our tick to achieve BS 7177 compliance. However, there may be trace amounts of chemicals from the growing and/or cleaning processes of the natural fillings contained within the mattress. If you have a medical condition or allergy that could be affected by the use of chemicals, please speak to your doctor or GP in the first instance. In such circumstances Harrison Spinks cannot be held responsible as the use of the product is done so at the individual’s own risk.
