Functionality and heavy-duty
At Rune Seikou, we have long been committed to incorporating exceptional design into every product we create, ensuring that each piece not only looks aesthetically pleasing but also serves a functional purpose. We pride ourselves on offering our products at a price point that is accessible, making them available to a wide range of customers while ensuring that everyone can enjoy the benefits of high-quality design without any concerns about affordability or value.
Over 60 years of experience
We have been developing and producing interior items, with a focus on chairs, based on our unique ideas and the ability to materialize and commercializethem.During product development, we prioritize high functionality and safety, as well as a longer life through replaceable parts and environmental performance that allows for easy recycling when discarded.
A wide variety of iron furniture
Rune Seikouʼs chair lineup is the ProWork series, which is now used by professionals around the world, representing Japanʼs cutting-edge industrial and academic research facilities. It is also highly regarded by top musicians worldwide as the ideal chair for performances.
For three generations, we’ve mastered metalworking and pioneered furniture design, driven by a passion for innovation.
Though chairs became common in Japan just 150 years ago, I take pride in exporting authentically Japanese designs to Europe and America. Our chairs are more than furniture—they’re trusted tools for professionals, blending functionality with artistry.
Safety is our top priority. Chairs are meant to support people, a responsibility we take seriously.
Our creations are not imitations but cutting-edge masterpieces. I invite you to experience the future of seating and make our products part of your world.
Environmental consideration
Environmental Aspects of Iron
Recyclability:
Iron is highly recyclable. Recycled iron, or scrap iron, is used extensively in steel production, reducing the need for raw
materials and minimizing energy consumption.
Recycling iron saves a significant amount of energy compared to producing new iron from ore, which helps reduce the
overall carbon footprint
Durability:
Iron and steel are durable materials, meaning products made from iron (like furniture or structures) last longer and don't
need to be replaced frequently. This reduces waste over time.
Abundant Supply
Iron ore is abundant in the earth's crust, making it a widely available and relatively low-cost material. This reduces the environmental impact of sourcing compared to rarer materials.
