David Thulstrup’s Limited Edition Furniture Collection for Søuld.

David Thulstrup unveiled a limited edition furniture collection made using eelgrass Acoustic Mats engineered by Søuld. Dubbed Momentum, the collection explores the tactility of eelgrass through four limited-edition designs: a Low Table, High Table, Podium and Screen.

With a focus on the senses, each piece integrates glass and steel with Søuld’s eelgrass Acoustic Mats—a CO₂-storing, environmentally friendly and healthy building material made from an abundant local sea plant. Thulstrup’s designs evoke the warmth, organic softness and pre-industrial humanity of Søuld’s Acoustic Mats—referencing the eelgrass plant’s natural origins and the forgotten legacy of Læsø’s seaweed houses.

Thulstrup says of the material: “Working with eelgrass feels rewarding not only because of its truly unique characteristics, but also the fact that it’s natural, sustainable, and revolutionary. I especially love the surface of the eelgrass, its warm hue, and the smell of salt.” The result is a collection of honest and sensorial designs that improve the acoustics within spaces whilst connecting modern interior design with nature.

Speaking about his creative vision, David Thulstrup says: “Visiting Læsø and understanding the history of the place played a huge role in the design process. Once I started to dissect how the eelgrass was used and applied in building the roofs back in the days, I realised that methods like layering, stacking and exposing the material would be an integral part of my designs.”

Momentum utilises Søuld’s eelgrass Acoustic Mats—a new material invented by Søuld with a goal to reduce the environmental impacts of the building industry and provide healthy living spaces. Eelgrass’ use in construction dates back to the 1600s, when settlers of Læsø island would forge thick roof-thatching for their ‘seaweed houses’—a technique unseen anywhere else in the world. Enhanced through state-of-the-art technology, Søuld’s work represents a passionate reinvention of Denmark’s forgotten seaweed house heritage. After a decade of research and development, Søuld has emerged as an expert in eelgrass and is the first company to convert the material into CO₂-storing building materials that combine high acoustic performance, safety and durability with sustainability and modern aesthetics.
