Prostoria’s Sustainable Revolution: How Croatian Craftsmanship Is Redefining Conscious Furniture Design
Croatian furniture brand Prostoria has long been celebrated for its elegant blend of minimalist aesthetics and forward-thinking design, earning a respected position in the world of contemporary European interiors. With signature pieces like the Rhomb and Dobra chairs that combine striking silhouettes with ergonomic precision, Prostoria continues to set a benchmark for quality craftsmanship. Yet beyond the artistry and engineering behind each piece lies an equally vital driving force: a deep and ongoing commitment to sustainability that permeates every aspect of the company’s operations. This is not simply a marketing tagline or corporate initiative—it is a philosophy that shapes how the brand sources its materials, designs its products, operates its facilities, manages its waste, and even reinvents its leftover resources.
From the outset of any new collection, sustainability is embedded into the design process itself. The goal is not just to create beautiful furniture, but to design pieces that can endure the test of time—not merely physically, but aesthetically and ethically. Products are crafted to age gracefully, incorporating traditional materials like solid Slavonian oak, a wood native to the region and known for its strength and beauty. This local sourcing reduces the environmental impact of transportation while supporting the surrounding economy. More importantly, it ensures that the wood used is traceable, responsibly harvested, and meets rigorous ecological standards. The natural qualities of the materials are carefully considered and emphasized throughout the production, with particular attention paid to how they interact with the human body and daily use. Finishes are selected not only for their visual appeal but also for their durability and non-toxicity, ensuring that the furniture remains safe and functional in homes and public spaces for decades.
One of the most innovative manifestations of Prostoria’s green ethos is Štof by Prostoria, a retail concept and platform located in Zagreb. This circular economy initiative redefines how leftover materials and outdated inventories are treated. Rather than relegating surplus textiles to landfills or discount bins, Štof repurposes these fabrics in creative and practical ways. At its core, the shop is a curated space where textiles from previous collections are given new life—sold to customers who value unique fabrics and conscious consumption. But the initiative extends far beyond mere resale. The shop also functions as a studio where vintage furniture is carefully restored, breathing new vitality into well-worn pieces that still have structural integrity and charm. Skilled artisans evaluate each item, reinforcing frames, replacing padding with eco-friendly alternatives, and reupholstering with leftover fabrics from Prostoria’s archive.
In tandem with restoration efforts, Štof by Prostoria also spearheads design projects that explore new uses for remnant materials. One of the more successful experiments has been the creation of tote bags, crafted entirely from leftover textiles. These bags are not mass-produced accessories but limited-edition items, each one a kind of functional artifact that narrates the aesthetic evolution of Prostoria’s collections over the years. Offering two styles of bags, the project aims to make sustainable design accessible and appealing to a broader audience, inviting everyday participation in the circular economy. Additionally, rather than allow smaller fabric scraps to go to waste, Prostoria donates these remnants to local schools, where they become valuable resources for art programs and craft workshops. This kind of grassroots support not only diverts waste but also nurtures creativity in the community, planting seeds of awareness and appreciation for sustainability in the minds of younger generations.
While design and restoration are central to Prostoria’s sustainability mission, the brand also emphasizes environmental responsibility at an operational level. The factory and research laboratory located in Sveti Križ Začretje represent a model of how industrial production can align with ecological principles. The facility holds a series of internationally recognized certifications, including the FSC® (FSC C136756 Chain of Custody), which verifies that the wood used in production is sourced from responsibly managed forests. In addition, Prostoria adheres to ISO 9001:2015 standards for quality management and ISO 14001:2015 environmental management. These standards ensure that every step of the production process, from procurement to packaging, is executed with a level of discipline and transparency that prioritizes sustainability alongside quality and efficiency.
Moreover, the choice of suppliers and collaborators is never incidental. Prostoria maintains a rigorous selection process to ensure that its manufacturing partners share the same commitment to environmental stewardship. Only those suppliers that can provide raw materials with documented longevity, recyclability, and low ecological impact are chosen. This collaborative approach strengthens the integrity of the final product and amplifies the company’s sustainability impact across the broader supply chain. Every piece of wood, metal, foam, and fabric that enters Prostoria’s production facility has been scrutinized not just for performance and beauty but for its lifecycle implications and afterlife potential.
Waste management, a pressing concern in furniture manufacturing, is treated with utmost seriousness. Instead of viewing production remnants as unavoidable loss, Prostoria approaches waste as a potential resource. For example, sawdust and other wood shavings generated during the shaping and sanding processes are collected and sold to the wood-pellet industry, where they are transformed into renewable heating materials. Similarly, smaller wood offcuts that are too irregular for industrial reuse are distributed within the local community as firewood, supporting both circularity and energy independence on a micro scale. Metal waste, another byproduct of furniture fabrication, is not discarded but sent to a nearby foundry where it is melted down and repurposed, ensuring that these materials remain within the production loop rather than contributing to landfill overflow or environmental degradation.
Not all waste, of course, can be handled internally. Hazardous materials such as wastewater, chemical adhesives, and industrial packaging residue require more specialized care. To that end, Prostoria partners with certified environmental services companies who are equipped to manage, treat, and dispose of these materials in compliance with strict regulations. These relationships ensure that even the more challenging aspects of industrial waste are addressed responsibly, without cutting corners or compromising public health.
Creativity is yet another dimension of Prostoria’s environmental philosophy. Recognizing that the boundary between waste and material is often a question of perspective, the company has taken bold steps to reimagine industrial remnants as sources of inspiration. Anđela Vilić, Prostoria’s Head of the Quality Management System and also an accomplished sculptor, has developed a series of art installations that incorporate discarded components, offcuts, and manufacturing byproducts. These installations, exhibited at Prostoria’s retail spaces and design fairs, blur the lines between art, architecture, and sustainability, offering viewers a provocative look at how design waste can be transfigured into objects of meaning and beauty. Rather than conceal the remnants of production, Prostoria brings them into the spotlight, using them to initiate conversations about responsibility, transformation, and value in the modern world.
Prostoria’s sustainability model operates on a principle of continuity—linking the past with the present, the local with the global, the industrial with the artisanal. It is a model that recognizes the interconnectedness of ecosystems and economies, and the importance of designing not only for aesthetics but for endurance and empathy. The company’s investment in education, transparency, community, and experimentation represents a comprehensive vision of sustainability, one that refuses to isolate environmental action from cultural and economic realities. Instead, it integrates them, turning sustainability from a checklist into a living practice.
As design consumers become more discerning and more attuned to the environmental impact of their choices, brands like Prostoria serve as crucial examples of how style and sustainability can not only coexist but elevate each other. They demonstrate that luxury does not have to mean excess, that innovation does not have to come at the earth’s expense, and that a well-made product should be as generous to the planet as it is to its owner. In an era where fast furniture and disposable design continue to dominate parts of the market, the deliberate, conscious methodology employed by Prostoria feels not only refreshing but essential. It speaks to a deeper desire among consumers and creators alike—to participate in systems that reward care, ingenuity, and responsibility. Through its holistic approach to sustainability, Prostoria invites the design world to reimagine what’s possible when beauty and ethics are allowed to evolve together.
