Belay is an active office chair that questions the state of our sitting culture. All stuck in the same position, hunched over desks, our posture undeniably suffers. The chair lies somewhere between the bouncy extravagance of exercise balls and the technical possibilities offered by ergonomic chairs. Correcting one’s posture requires a conscious effort. This awareness is initiated by an active element consisting of an oscillating seat combined with a rotating base. This mechanism actively stimulates the muscles of the seated person, making them reflect on the quality of their posture. The initial intention was to inject a level of playfulness into the office space that did not interfere with work, reflecting a more balanced approach to our health at work.

‘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 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 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 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.

During this one-week workshop led by Thélonious Goupil, edits were made to a ‘drop false ceiling’ in Bar Gala Lausanne. By hacking the system, playing with existing elements such as lighting or ventilators, the outdate ceiling was given new life without the need for full renovation.
