Host is one of the most versatile armchairs for public spaces in the Sitlosophy collection, designed to integrate effortlessly into a wide variety of interiors. Its essential silhouette and contemporary design, minimal yet welcoming, make it ideal for restaurants and break areas, waiting rooms, offices, lounge spaces and even modern residential environments. The enveloping shell, balanced proportions and comfortable seating ensure a pleasant and durable user experience.
The new metal-base versions – available with four legs or a sled frame – expand Host’s functional possibilities, allowing designers to choose the most suitable base for each type of project. Powder-coated finishes in trendy colours enable elegant tone-on-tone compositions or bolder contrasts with the selected upholstery.

Host was created to meet the needs of the contract world with the right balance of comfort, durability and identity. Its contemporary design focuses on the purity of shapes and visual lightness, enabling it to adapt to different architectural styles without imposing its presence. The shell combines soft curves with a clean geometric structure, offering natural ergonomic support for prolonged use typical of workspaces and break areas.
The metal frame is one of the defining elements of the Host collection, available in two dedicated versions:
Four-leg base, perfect for restaurants, meeting rooms, waiting areas and shared spaces where stability and versatility are essential.
Sled base, ideal for informal areas, lounge spaces and dynamic interiors where an elegant, lightweight seat enhances the atmosphere.
Host’s wide range of upholstery options and colour finishes allows complete customization, enabling designers to develop tone-on-tone solutions or expressive material contrasts. As a truly efficient armchair for public spaces, Host is designed to withstand intensive use, offering easy maintenance and long-lasting quality.
Sitlosophy also provides extensive technical documentation, including digital catalogues and lifestyle images, which help create moodboards, define colour palettes and evaluate Host within different interior scenarios. These materials support every step of the design process, facilitating client communication and accelerating decision-making.
Host is ideal for restaurants and break areas, lobbies, lounges, offices and any contemporary public environment that requires comfort, aesthetic coherence and functional performance.
The versatility of Host makes it suitable for a wide range of settings. In restaurants and cafés, its stability and quality finishes ensure comfortable, long-lasting seating even during intensive use. In corporate break areas, Host helps create warm and welcoming zones that encourage relaxation and informal interaction.
In offices and waiting rooms, its essential look conveys order, visual clarity and professionalism, contributing to a pleasant and contemporary atmosphere. Host also adapts well to residential environments, where it functions as an elegant solution for study corners, living rooms and lounge spaces.
The ability to customize upholstery, finishes and metal colours makes Host a valuable resource for architects and interior designers seeking consistency across large projects. Using digital catalogues and lifestyle images, professionals can simulate Host’s placement within different layouts, improving communication with clients and partners and streamlining the entire design workflow.
In hotel lobbies, lounge areas and high-traffic public environments, Host stands out for its durability and its ability to maintain a clean, contemporary aesthetic over time. The sled version conveys lightness and movement, while the four-leg version ensures stability and adaptability in all configurations.
More than just a seat, Host is a complete project solution designed for restaurants and break areas, dynamic spaces and all contexts where aesthetics, functionality and design coherence must coexist seamlessly.
