The patented innovation is made with hydrolysed collagen – a by-product of Muirhead’s own leather manufacturing process. With 20% bio-content, the product eliminates concerning substances such as melamine and PFAS (‘forever chemicals’) found in traditional seat foams, resulting in enhanced fire safety, durability, passenger comfort, and clear environmental benefits.

By combining leather seat covers and BioPRO cushions, Muirhead now delivers a seamless, one-stop seating solution with consistent aesthetics and precise dimensions. This fully integrated approach simplifies the development process, reduces lead times, and streamlines the supply chain with a single point of contact.

Dr Warren Bowden, Head of Innovation & Sustainability at Muirhead and Scottish Leather Group, said: “By incorporating our own bio-protein into the foam’s chemistry, we’ve eliminated the need for harmful additives while improving durability. This sets a new benchmark for next-generation seat foam technology and reflects our commitment to vertically integrated, circular manufacturing.”

Muirhead chemically bonds collagen to the foam chemistry, resulting in a seat foam that is stronger, more durable and intumescent. This process ensures the bio-content becomes a functioning part of the foam, eliminating internal abrasion and expanding its lifespan.

The product is designed to adapt, providing targeted support for different body types. Independent testing confirms its exceptional ergonomic performance, ensuring a superior seating experience for a diverse range of passengers.

While traditional foams are cut from large blocks, BioPRO is moulded to the customer’s precise specifications. This unique approach eliminates waste and offers complete customisation for airlines, seat OEMs and airframe manufacturers. The moulded cushions ensure consistent shape and size, guaranteeing uniform aesthetics throughout the cabin.
