Designed by Edi & Paolo Ciani, Metropolitan Lounge perfectly balances contemporary aesthetics with high-level ergonomic comfort. This collection of lounge armchairs is conceived to offer a superior seating experience thanks to its enveloping shell and the free-swing harmonic movement available on the executive models. Its fluid lines and refined proportions create an elegant presence, ideal for lounge and relaxation areas in corporate spaces, hospitality environments, retail interiors and public areas.
The Metropolitan Lounge family includes high-back, mid-back and compact lounge armchairs, each offering different levels of comfort and visual impact. Its Made in Italy quality emerges clearly in the craftsmanship of the upholstery, the precision of the stitching and the meticulous material selection.
Another strong point of the collection is the high degree of customization: the customizable options (colors, fabrics, finishes) allow designers to adapt each model to the identity of the project. The bases include four-star aluminum, stainless-steel disc, and solid ash wood legs, enabling stylistic solutions that range from executive environments to more informal lounge settings.

The Metropolitan Lounge collection offers a complete range of models developed to meet different functional and aesthetic requirements. The executive models — C8070AB (aluminum 4-star base) and C8070AV (Ø600 stainless-steel disc base) — represent the most prestigious and comfortable version, thanks to the high backrest and harmonic oscillation movement. These lounge armchairs are ideal for executive offices, premium waiting areas, luxury hotels and receptions where visual impact is essential.
For those who prefer a more compact presence without sacrificing elegance, the C8071B semi-executive version offers a medium-height backrest and a four-star aluminum base, maintaining the same distinctive identity of the high-back models. It is perfect for lounge areas, collaborative spaces and conversation rooms.
The family also includes smaller lounge armchairs designed for flexible and contemporary environments:
– C8072B featuring a 4-star aluminum swivel base;
– C8072V with Ø470 stainless-steel disc base;
– W-N8072V, with four solid ash wood legs, ideal for hospitality spaces, relaxation zones and warm, welcoming interiors.
All models are customizable through the wide range of customizable options (colors, fabrics, finishes), with choices including fabric, leather, faux leather and bicolor combinations. Bases available in polished aluminum, black-painted finishes, stainless steel or wood allow the collection to blend seamlessly into any architectural concept.
Thanks to the harmony of its shapes, ergonomic comfort and flexible configurations, Metropolitan Lounge is one of Sitlosophy’s most iconic and versatile lounge seating solutions.
In contemporary interior design, lounge and relaxation areas play a strategic role. These spaces are meant not only for waiting, but for informal conversation, decompression and connection. The various models of Metropolitan Lounge are conceived to respond to these new dynamics, offering the right blend of comfort, aesthetics and modularity.
The range of models allows designers to build coordinated and harmonious spaces: high-back versions for scenic reception areas, mid-back versions for breakout spaces, and wooden-leg variants for warm hospitality environments. This versatility makes the collection ideal for lounge and relaxation areas, coworking spaces, boutique hotels, meeting zones and public interiors.
The Made in Italy quality is reflected in the precise construction, refined materials and attention to long-lasting performance. Every curve, stitch and finish has been designed to withstand intensive use while maintaining its elegance and structural integrity over time.
The broad selection of customizable options (colors, fabrics, finishes) enables complete integration into the project’s moodboard: neutral tones for formal settings, vibrant colors for creative areas, soft-touch fabrics for relaxation zones, or bold bicolor combinations to achieve a contemporary and expressive look.
Metropolitan Lounge is not just a collection of armchairs — it is a true design tool that enhances any environment with its contemporary elegance, superior comfort and timeless aesthetic.
