How material innovation is shaping the future of fire-safe, sustainable, non-toxic furniture

The UK Government’s proposed reforms to furniture fire safety regulations have brought renewed attention to the balance between fire performance, chemical exposure and sustainability in modern interiors.

These reforms are potentially controversial, especially when we consider the growing presence of household items powered by lithium-ion batteries, which can cause fires. The changes could also be viewed as an unnecessary trade-off.  

The consultation, which closes on June 23rd this year, aims to reduce the use of chemical flame retardants in domestic upholstered furniture while maintaining high safety standards. It follows growing public and media scrutiny around the environmental and health impact of some fire-retardant treatments.

Recent headlines around so-called ‘toxic sofas’ have highlighted increasing concern about the materials used in furniture manufacturing and what this means for consumers, manufacturers and the wider environment. In March this year, the International Agency for Research on Cancer (IARC), the specialised cancer agency of the World Health Organisation, classified tris(chloropropyl) phosphate (TCPP), a flame retardant found in polyurethane foams, as “probably carcinogenic to humans” (Source)

But of course, alongside these concerns, fire safety remains a critical consideration, even though greater public awareness and more sophisticated smoke detection systems have significantly improved the situation. In 2024, 92% of UK households reported owning a smoke alarm, compared with less than 10% in 1988. (Source) However, the risks remain and must never be underestimated.

Modern homes and public spaces contain a growing mix of synthetic materials, electronic devices and lithium-ion batteries, creating a more complex fire-risk environment than when the original Furniture and Furnishings (Fire) (Safety) Regulations were introduced in 1988. On average, there’s a fire from a lithium-ion battery in an e-bike or e-scooter every two days in London. Many of these fires happen in homes while batteries are charging. (Source)

For manufacturers, designers and policymakers, the challenge is clear, yet complex. How can the industry continue to improve sustainability and reduce reliance on chemical additives in furniture, while still maintaining the high levels of fire performance required in residential and commercial environments?

Importantly, this should not become a debate that pits fire safety against sustainability and protection from chemical exposure. The challenge is to develop a solution that addresses all three issues. And advances in materials innovation are helping demonstrate that these objectives can co-exist.

At Muirhead, the principle of achieving all three objectives shaped the development of BioPRO Foam and the company’s naturally high-performing leather materials. BioPRO Foam is a bio-based, low-emission material designed to meet demanding performance standards without the need for supplementary flame-retardant treatments. In addition, Muirhead leather is equally a bio-based, low-emission material that can meet stringent UK furniture fire performance requirements, including BS 5852 Ignition Source 5 (Crib 5); a UK fire safety standard used to test upholstered furniture and seating materials for resistance to ignition by a large, open flame, and cigarette and match-ignition resistance tests, without modification.

Together, these materials deliver a complete, whole-seat solution – from foam insert to leather cover – supporting durability, comfort, and compliance while reducing reliance on additional chemical treatments.  They also meet growing industry demand for materials that can help future-proof furniture and interior design against evolving regulatory, environmental and customer expectations. At the same time, they support the transition towards lower-impact manufacturing and material specification.

Across domestic, commercial, public and high-traffic environments – from hospitality and workplace interiors to transport lounges and premium seating applications – manufacturers are increasingly seeking materials that can support both safety and sustainability objectives without compromise. Muirhead’s BioPRO Foam has been developed to support that requirement.

As the industry continues to evaluate the future direction of fire safety regulations, the opportunity is not simply to replace one set of materials or treatments with another. It is to encourage a more holistic approach to furniture and seating design, in which material performance, environmental impact, durability, and occupant wellbeing are considered together.

For manufacturers and suppliers, this presents an opportunity to rethink how interiors are designed and specified for the future - through material innovation that delivers performance, sustainability, and occupant wellbeing in tandem.
