About Oco Armchair
The Oco armchair is a minimalist piece with a strong, elegant and original look. Its name refers to the empty space inside a hollow sphere and it is in this space that those who sit in it are accommodated. The upholstery is ergonomic and soft and the piece comes in a variety of finishes, such as natural wood veneer, lacquer, electrostatic paint and others. The Oco armchair is an example of timeless design, whose aesthetic language breaks the barrier of trends and focuses on the authenticity of ideas.

Grand Interview
Your innovative approach to the Oco Armchair's hollow sphere design has earned recognition with a Silver A' Design Award. Could you elaborate on how this distinctive geometric form enhances both the aesthetic and functional aspects of the piece?
The hollow hemisphere was conceived as the central element of the Oco Armchair, reflecting my pursuit of exploring the visual and symbolic strength of pure geometry. This choice was not solely aesthetic but also functional. The spherical form, with its symmetry and continuity, creates an experience that naturally, almost intuitively, embraces the human body, providing physical comfort and a sense of protection. At the same time, the piece establishes a dialogue between functionality and artistic expression. The simple and precise geometry evokes a minimalist language, while its striking presence invites reflection on the role of everyday objects in our environment. My intention was to go beyond utility, proposing a design that also fosters emotional and intellectual interaction with the observer, positioning the armchair as a balance between functional furniture and a piece of contemporary art. This concept adds a deeper meaning to the design, connecting aesthetics, utility, and purpose.
The Oco Armchair seamlessly combines minimalist design with ergonomic comfort through its fiberglass shell structure. What inspired you to explore this particular combination of materials and form, and how did it evolve during the development process?
The inspiration to combine the minimalist design and ergonomic comfort of the Oco Armchair arose from a desire to explore contrasts—strength and softness, simplicity and sophistication. Fiberglass was chosen not only for its structural integrity but also for its versatility in shaping organic, continuous forms that align seamlessly with the chair’s minimalist aesthetic. Additionally, this material allowed us to achieve a clean, fluid silhouette while ensuring both durability and stability. The development process was a lengthy and exhaustive journey. The focus was on creating a visually lightweight structure that remained sufficiently robust to support adequate loads. During prototyping, we explored different thicknesses and fiberglass stratification techniques to ensure the shell maintained its slim profile without compromising strength. The combination of the fiberglass hemisphere and the upholstery was a deliberate choice to contrast rigidity and softness. This pairing reflects the dual purpose of the armchair: to serve as both a design object and a functional piece of furniture. Throughout the development process, ergonomics were refined by adjusting the curvature, proportions, and finishes, ensuring not only a striking appearance but also a welcoming comfort. The dialogue between materials and forms embodies the ethos of the armchair: a minimalist design rich in experience, seamlessly blending artistic expression with human-centered functionality.
Your description mentions that the Oco Armchair required several prototypes to achieve the desired result. Could you walk us through the most challenging aspects of working with fiberglass and natural wood veneers on organic surfaces, and how you ultimately overcame these technical hurdles?
The prototyping process of the Oco Armchair involved complex stages and significant time investment, particularly due to the challenges of working with fiberglass and natural wood veneers applied to an organic, spherical surface. It demanded innovation, extensive experimentation, and persistence to achieve the desired result. For fiberglass, the main challenge was ensuring a uniform, slender, and sufficiently robust structure with perfect fittings, providing the necessary structural integrity for the project. Ensuring strength at the connection points between the shell and the steel base was perhaps the aspect that required the most attention. Regarding the natural wood veneers, the difficulty lay in adapting a material with limited flexibility in multiple directions to a spherical surface, avoiding cracks, deformations, and visual imperfections. The solution came through highly specialized craftsmanship in marquetry, which helped refine the processes of cutting, bending, and attaching the veneers. Additionally, we opted for wood species with greater flexibility. The meticulous development of the Oco Armchair required intense collaboration between industrial and artisanal processes, deepening our appreciation for the value of manual craftsmanship within the design context.
Behind the Design
Press Kit
Credits, team members and technical details provided by the designer.
- Unique Properties
- The Oco armchair translates a design with non-complex shapes, simple in its aesthetics but strong visually.
Its name refers to the hollow shell made of fiberglass that carefully houses the upholstery. The half-sphere shape is the main element of the piece and can be made in a variety of finishes, such as lacquer or laminated wood. The laser-cut carbon steel legs also come in a variety of finishes.
The upholstery is soft and ergonomic, successfully fulfilling its main function as an armchair. - Dimensions & Packaging
- Product dimensions: L880 mm x W880 mm x H720 mm

- Production Technology
- Several prototypes were needed to achieve the desired result. First, a plywood mold was developed to produce the fiberglass half-sphere. Next, we developed the laser-cut carbon steel feet. Finally, we developed the upholstery, using high quality, soft foams. A 12 kg metal profile was added to the backrest cushion to give the product greater stability. The fiberglass structure can be coated with lacquer or natural wood veneers.
- Design Challenge
- There were two main challenges in developing this product. One was certainly the process of laminating the fiberglass half-sphere. Working with natural wood veneers on organic surfaces requires skilled labor, time and a lot of care.
Another major challenge was fitting the half-sphere to the feet. The project required an aesthetically clean connection and it took many tests before we got the final version. Achieving the result we did was an arduous task, but one I'm very proud of. - Research
- Form and function must be inseparable allies in the construction of a product. The user's expectation must be to be involved when sitting down as much as to see a product that generates desire. We started from this point and tried to succeed in this proposal.
The Oco armchair is the synthesis of this search, resulting in a product whose material, aesthetic and functional aspects do justice to the purpose of being complete without, however, being separated from existing design icons. - Inspiration
- The Oco armchair is inspired by the search for aesthetic simplicity, combined with originality in the harmonization of shapes.
As its name suggests, the shell in the shape of a half-sphere, produced in fiberglass and hollow inside, translates the idea behind its design, producing a pleasant and striking aesthetic and, at the same time, intriguing from a production point of view. - Project Duration
- The armchair began development in May 2022 in Sarandi and was launched in January 2023 at a private event in the state of Paraná, Brazil.
- Operation Flow
- With proportional dimensions, the Oco armchair is a product designed to fulfill its function and at the same time provoke contemplation and desire.
The upholstery is soft and ergonomic, as proven by experiments on different types of bodies during its design. The backrest cushion is loose and can be moved to adapt it to the best sitting position. The seat, on the other hand, is fixed and stable. The armchair does not tip forwards or backwards and can support more than 150 kg. - Image Credits
