“OFFSET” is a series of sustainable, sculptural stools designed by Natural Material Studio. The stools consist of biodegradable madress foam, B-Foam, and Dinesen Douglas fir offcuts. The series of stools is developed from the construction principle of offsets, where the same dimensions are replicated and moved, which creates a lively and ukurant expression of changing the look within the same frame. The offset changes in the construction is meant to compliment the varying and unique character of the foam texture.

The foam that is used as the seat of the stools consists of a foaming technology with a protein based bio-polymer, all developed by the studio. To create a washable and durable surface, the studio has incorporated beeswax into the foam that creates an outer barrier. This makes it possible to expose and use the foam both as a padding and lining at the same time.

The foam biodegrades within 3 months when exposed to soil, compost, or heat and water in combination. The latter makes it possible to reuse and recast the material, and thereby create a closed loop system.

The “OFFSET” stools comes in three variant constructions, #01, #02, #03, and in either white washed or ash pigmented Douglas fir offcuts. The stools are sold individually. All foam seats and wood constructions are handmade by order.

About the designer

Bonnie Hvillum

We want to create a future that is fully centred around the circular design principles - reuse, recycle, renew & rethink. That is why we are called the Natural Material Studio, as materials are the building blocks in all designs in the world – from packaging to architecture. The Studio is founded and run by material & interaction designer Bonnie Hvillum: “I am educated to design interactive user experiences, but the playful game of using up what I have with sustainability in mind has always been a great part of me. Establishing my studio on these to pilars – immersive interactions based on residue, let me to Natural Material Studio. I see my working approach very childish, with a naive beginners mind, but also very visionary constantly exploring the potential in the overseen to create highly sensory experiences.”

Curated by

Presenting “PROXIMITY”, a collection created in collaboration with Southern Sweden Design Days showcasing a selection of new work from ten designers and studios. As a whole, the collection contemplates the notion of proximity, interconnection, and belonging. Whether through contemporary references to traditional crafts techniques; the use of locally sourced materials such as wool, lichen, steel, and wood; or playful visualisations of the notion itself, the selected pieces illustrate the importance of closeness, interconnection, and kinship in uncertain times. Featuring pieces by Andrea Santivanez, Andréason & Leibel, Ebba Lindgren, Förstberg Ling, Jóna Berglind Stefánsdóttir, Lab La Bla, Lisa Darland, Louise Hederström, Moa Lönn, and Studio M. Organised by Form/Design Center in Malmö, Sweden, Southern Sweden Design Days is an annual event currently in its second edition, which highlights sustainability, collaboration, development, and innovation in design. This year’s theme, as described by the event organisers, “[reflects] on the notion of being close – the connection between people, cities, countries, species, professions, etc”. The physical exhibition of “PROXIMITY” will take place at Lokstallarna, Södra Bulltoftavägen 51, 212 22 Malmö from 19 - 22 May 2022.
