SPECTRUM SYSTEMMORE THAN A SOFA

Polygon emerged at a moment when Prostoria was defining its identity beyond function, seeking a clearer design language rooted in structure, comfort, and cultural continuity. Reflecting the brand’s early spirit of research and openness to new forms, the chair questions conventions and expands the language of upholstered furniture.

As the founder and curator of Good Goods — a virtual gallery dedicated to modern design and contemporary authors — he explores the emotional and cultural depth of objects beyond trend and market value.

Monk was conceived within a broader architectural vision for Hotel Dubrovnik Palace. In 2013, following their acclaimed work on Design Hotel Lone in Rovinj, studio 3LHD approached the redesign of the hotel’s rooms and restaurant as an opportunity to articulate a distinct identity shaped by context rather than simply update the interior. Furniture was understood as part of that architectural whole.

Within this framework, Monk took shape as a bespoke chair, conceived by studio Grupa and brought into being through Prostoria’s product development and production. Informed by the region’s modernist heritage, its design favoured structural clarity and restraint over stylistic expression, aligning naturally with the architectural logic of the space.

While designing the luxury Mulini Beach in Rovinj, the architectural studio 3LHD developed a distinctive piece of outdoor furniture, conceived specifically for the project’s spatial and atmospheric context. Recognizing its broader potential, 3LHD approached Prostoria with the idea of evolving the initial design into a complete outdoor collection and bringing it into production. It was only through this process—when the architectural concept, developed in close collaboration with Prostoria’s R&D team, grew into a coherent family of furniture—that the collection received its name: Umomoku, preserving its original character while expanding its possibilities across different settings.

Prostoria is participating in ICONIC PIECES – Design Post Celebrates 20 Years of Design History, a curated anniversary exhibition marking two decades of Design Post Cologne as a key European design platform. The exhibition reflects the evolution of European design over the past 20 years. Prostoria is represented both through its permanent showroom at Design Post and as one of 34 international brands selected for the anniversary exhibition.

We launched the photographic project Revisiting Architecture in 2020 to explore one of our key sources of inspiration — Zagreb’s modernist heritage. For us at Prostoria, modernism is not a style tied to a specific historical period, but a cultural foundation: a way of thinking about design as rational, honest, and human-centered. Modernist values of proportion, clarity, and optimism continue to shape everything we create. Revisiting Architecture is part of Prostoria’s communication trilogy — alongside Revisiting Analogue and Revisiting Factory — which addresses the key themes central to Prostoria’s identity and values.

In Prostoria’s new film House Le, designer Martin Pohl invites us into two closely connected spaces: his own home just outside Zagreb, and House Le — an interior design project shaped by the rhythms of everyday life. Moving between the personal and the professional, the film reveals how interiors emerge through comfort, contrast, and lived experience rather than rigid stylistic rules.
