The Ocean Collection
Originally produced in wood veneer, the outdoor furniture collection was first designed in 1955 by Jørgen and Nanna Ditzel - one of the 20th century's most renowned design duos. The chair was then named Havestol by Nanna & Jørgen Ditzel, which translates from Danish to ‘garden chair.’ The series featured a frame made of red, white or black lacquered steel tubes, paired with a laminated beech seat and a choice of ash or teak veneer. Havestol was produced by Poul Kolds Savværk in Kerteminde, on the island of Funen, Denmark, and was only in production for a short period of time.
Since 2019, Mater has been reimagining these robust designs in an effort to tackle various waste streams while simultaneously paying homage to Danish design heritage. Currently, we have four colourways – Black, Sand, Green, and Rust Red – and we operate with three different waste streams for the collection production: fishing nets, pharma plastic waste, and electronic plastic waste.
Introducing
Ocean Dusty Blue and Special Edition Ocean Kinraden
in Collaboration with KINRADEN
A Shared Vision - in Blue
Driven by a shared interest in recycled materials and timeless design, Mater launches the Ocean Collection in Kinraden's iconic blue.
The collaboration is rooted in a mutual ambition to unite aesthetics and long-lasting design. Both companies work with materials from waste: Mater with plastic from post-consumer e-waste, and Kinraden with recycled silver. The collection is connected not only by color, but by the origin of its materials. Both the plastic used in the Ocean furniture and the silver in Kinraden’s jewelry emerge from the same waste stream: electronic waste.
The Ocean Collection in blue is therefore more than a new color. It is a story of thinking across disciplines and generations, and of creating objects in which aesthetics and recycled materials meet.
Jørgen & Nanna Ditzel
Nanna & Jørgen Ditzel were born in respectively 1923 and 1921. They met each other at the Danish School of Arts and Crafts in Copenhagen, where they both were students. In 1946, they established their design studio. The period from 1946 to 1961 was very productive for the young couple. After Jørgen’s untimely death in 1961, Nanna continued their joint project alone. She became a prominent designer in a period when the Danish design and architecture scene was dominated by men.
In her work as a designer, she tackled everything from textiles to jewelry and furniture – finding a form and direction that pointed away from the strictly modernist, functionalist dictates issued by Kaare Klint and his school. She was actively producing designs until she died in 2005 and is known for her organic form and innovative use of materials, which helped redefine
Danish design aesthetics.

KINRADEN
Sarah Emilie Müllertz is an architect, creative director, and founder of KINRADEN. Born and educated in Denmark, she holds a master’s degree in architecture from the Royal Academy of Fine Arts in Copenhagen, where her sensitivity to space, material, and proportion was formed. Before focusing on jewellery, Sarah built a strong career in architecture. She ran her own design studio and later served as Partner and Global Head of Design at Henning Larsen Architects, leading international teams and shaping projects defined by clarity, structure, and cultural awareness. Her interest in art began early. A committed art collector since her teens, Sarah draws on a broad range of references - from contemporary and classical art to architecture and poetry, shaping a design language that is both informed and personal. Guided by a belief that responsibility and aesthetics must go hand in hand, she has embedded recycled precious metals and responsible material sourcing into KINRADEN from the outset.
