Omnia is a collection of ergonomic executive chairs designed for contemporary workspaces where aesthetics and functionality must coexist seamlessly. Developed with a clean and refined design language, Omnia stands out for its modern silhouette and its immediately perceptible comfort. Every detail is crafted to provide well-being throughout the working day, making it ideal for executive centers and managerial offices that seek a prestigious, comfortable and high-performance seating solution.
Its unique construction makes Omnia truly distinctive: the combination of metal armrests and the suspended-effect backrest creates a perfect balance of full and empty volumes, giving the chair both visual lightness and structural strength. The quality of the materials, the advanced ergonomics and the precision of details reflect Sitlosophy’s deep expertise and the excellence of made in Italy manufacturing. Architects and designers can rely on a wide range of finishes, fabrics and leathers, easily selectable through the dedicated moodboards and material boxes for architects, tools that support the creative and design phases.

Designed to become a statement piece in executive environments, Omnia reinterprets the concept of an ergonomic executive chair with a contemporary touch. The enveloping shape of the backrest, combined with the clean metal lines of the armrests, creates an elegant and highly functional whole. The suspended backrest is not only an aesthetic detail but an actual structural innovation that lightens the design and enhances user comfort.
Every element of the chair is carefully calibrated: the padding offers balanced support, the ergonomic mechanism promotes proper posture, and the wheeled base ensures stability and easy movement in any professional setting. For these reasons, Omnia is perfectly suited to executive centers and managerial offices that require furnishings capable of expressing authority without compromising well-being.
The made in Italy craftsmanship is immediately perceptible: premium materials, precise stitching and refined finishes highlight Sitlosophy’s design culture. Omnia also offers multiple configuration options suited to corporate environments, meeting rooms and high-level workspaces. Customisable upholstery and colours allow designers to define a coherent and distinctive visual identity.
To support architects and interior designers, Sitlosophy provides curated moodboards and material boxes, essential tools for selecting textures, colours and finishes that compose a harmonious palette. These resources simplify complex design processes and ensure perfect continuity between furniture and interior concept.
Omnia is the ideal choice for those seeking representative design, ergonomic performance and impeccable Italian quality. Its presence elevates executive spaces, creating refined and functional environments aligned with contemporary work dynamics.
One of the most appreciated features of the Omnia collection is its extensive customisation possibilities—a key factor for design professionals who need tailor-made solutions. Thanks to Sitlosophy’s made in Italy expertise, every component—from the metal structure to the upholstery—is produced with total control over materials, finishes and colours.
The metal frame is available in multiple finishes and pairs with a wide selection of coverings: technical fabrics, leathers, eco-leathers and premium upholstery options. This versatility allows Omnia to adapt easily to different design languages, from classic executive interiors to more contemporary managerial environments.
The dedicated moodboards and material boxes for architects provide an essential physical support for selecting textures and tones, enabling designers to define coherent palettes and refine complex projects. With these tools, the creative phase becomes intuitive and accurate, ensuring that every element fits harmoniously within the space.
Omnia is not just an ergonomic executive chair: it is a true design resource. Thanks to its configurability, refined aesthetics and advanced ergonomic comfort, it integrates seamlessly into reception areas, executive offices and meeting rooms.
The suspended backrest, combined with the distinctive metal armrest connection, gives Omnia a unique identity—subtle yet instantly recognisable. Its durability and functional reliability meet the highest industry standards, making it a long-lasting investment for professional spaces.
Omnia is the perfect synthesis of beauty, ergonomics and project flexibility: a seating solution that enriches executive environments and supports architects in creating refined, functional and fully customised spaces.
