Louis Bosnjak – Repose

by Louis Bosnjak

Traditionally, upholstered furniture is made from a mix of materials like wood, metal, polyurethane (PU) foam, glue, and fasteners—forming a complex composite that is nearly impossible to recycle. PU foam, the industry standard for comfort, is especially difficult to process and often ends up in landfills. Repose rethinks this system by replacing synthetic components with fully biodegradable, organic materials. Combining a cantilever wooden structure with flexible wood fiber panels, hemp cord webbing, kapok fibers, natural latex, and expanded cork, the project creates furniture that is comfortable, durable, and designed for biodegradability—offering a coherent, circular alternative to conventional upholstery.

Stool Story

with Christophe Guberan

‘Stool Story’ invited students to explore innovative, re-contextualised, or intriguing materials and production techniques to create a simple yet fundamentally structural typology: the stool. Each process was documented through a short, vertically formatted video. The result is a range of stools, each demonstrating a unique perspective and approach.

SolarPunk

with Philippe Malouin

SolarPunk is a design exploration into how increasingly accessible solar energy might shape and integrate into our everyday lives in the near future. Embracing a hopeful vision of sustainability, the movement challenges traditional perceptions of renewable energy by imagining creative, aesthetic, and functional uses of solar power. This collection of work was created by first-year Master’s students in Product Design at ECAL, under the guidance of designer Philippe Malouin. Developed specifically for the Soleil·s exhibition at the MUDAC design museum in Lausanne, the projects reflect bold experimentation and speculative thinking. Rather than focusing solely on efficiency or utility, the students explored poetic, playful, and sometimes unconventional applications of solar energy, highlighting the emotional and experiential potential of this technology. Among the featured works are two standout projects which have been developed and feature in the exhibition: ‘Solar Shade' by Carl Johan Jacobsen, a wearable hat that powers a cooling vest using flexible solar panels, and ‘Butterfly Sunglasses’ by Takumi Ise, simple lightweight eyewear that combines colour, movement, and solar functionality.

Designed in CH Made in JP

with Augustin Scott de Martinville

Designed in CH, Made in JP is a collaborative project between ECAL Master Product Design, Karimoku New Standard, and Presence Switzerland. From 13 April to 13 October 2025, representatives from countries across the globe will gather to showcase innovation, culture, and sustainability at the World Expo in Osaka, Japan. For Switzerland’s pavilion, MA Product Design students at ECAL were tasked with designing a stackable wooden chair to be produced in Japan by Karimoku New Standard, intended to furnish the lightweight, bubble-inspired architecture by Manuel Herz. Under the guidance of Augustin Scott de Martinville, the class developed ten chair designs, each offering a distinct perspective. Some draw inspiration from the pavilion’s scenography, while others explore cultural iconography or celebrate the symbiosis between two nations—each unique in heritage yet united by shared values of craftsmanship and innovation. Of the ten designs, one was selected to be produced for the pavilion: HUG, designed by Jacob Kouthoofd Martensson and Min Xiyao, is a circular chair that stacks inversely—a feature that not only informs its name but also visually embodies the essence of collaboration. This versatile design accommodates a range of uses, from conferences to general pavilion seating. The final chair will be unveiled both in Osaka in the Swiss Pavilion at the World Expo 2025, and during Milan Design Week 2025, with the full project exhibited at the House of Switzerland.

Heat Pumps for Viessmann

with Augustin Scott de Martinville

Heat pumps are energy-efficient household climate systems essential for transitioning to renewable energy and combating climate change. Typically installed outside close-by to buildings, they are becoming common visual elements in urban landscapes, often resembling air conditioners with limited design variety across brands. To reimagine these essential typologies, Viessmann, a world leading Heat Pump producer, invited MA Product Design students from ECAL to develop innovative concepts, resulting in designs that challenge norms and explore new visual identities of heat pumps.

Transformations

with Studio Isabel + Helen

This workshop was led by Isabel + Helen Studio, a duo of London artists known for their captivating kinetic sculptures and installations. They blend art with movement to create playful and thought-provoking works. During the week, they guided students through the fundamentals of creating dynamic, moving sculptures. Using umbrella mechanisms, students created fireworks.

I as an Island

with Chris Kabel

Like Robinson Crusoe scavenged the wrecked ship for materials to build his home, First Year Master Product Design students, guided by Chris Kabel, were invited to delve into the flotsam of their creative minds for this open workshop. The workshop began with collecting, organizing, and analyzing creative flotsam and jetsam to create a self-portrait as a designer. Unrealized projects, obsessions and fascinations, irritations, vague dreams, (bad) jokes, and ideas too weird to talk about—all these resided within a designer's mind. Beginnings already existed: inspiring photos on phones, inviting materials, first ideas hastily scribbled down, quick sketches on paper, half-baked assemblages, or flimsy maquettes. These fragments and particles were analyzed to discover the kind of designer each participant was, extracting a direction for development during the week. This process of analysis, ideation, and translation, including the ‘end result,’ became visible as an island, shaped and populated by each individual's design process. It featured fragile beginnings, iterations, and the choices made along the way, culminating in a final conclusion shaped by material samples, shape research, 3D sketches, the development of a mechanism, a campaign, a film scenario, or whatever else was distilled from the initial flotsam.

ECAL x MEHARI EDEN

with Elric Petit, Stephane Halmai-Voisard

The 2CV Méhari Club Cassis has developed an electric version of the iconic Citroën released in 1968 : the EDEN. From its inception, this car was designed for summer sports and leisure activity. Our current renewed interest in outdoor activities together with electric technology makes this car particularly attractive. With this in mind, the 2nd-year BA students in Industrial Design, under the direction of Stéphane Halmaï-Voisard, Head of Programme, and designer Elric Petit, showcase a series of accessories for tomorrow’s electric Méhari.
