Generous volumes, soft geometries and balanced proportions define Sadel, the collection of modular sofas and seating designed by Alessandro Crosera.
Inspired by the silhouette of a saddle, from which it takes its name, Sadel stands out for the distinctive shape of its backrests and armrests, giving the collection an instantly recognizable identity. Poufs, armchairs and sofas can be freely combined to create welcoming, versatile compositions that naturally complement contemporary spaces.

The technical datasheets and CAD libraries of the Sadel collection provide contractors, architects, and designers with all the tools they need to seamlessly integrate the collections into their projects. Files available in 2D, 3D, and Revit formats ensure precision, customization, and efficiency throughout the design process.
Sadel is Sitlosophy’s collection of designer modular sofas, created by Alessandro Crosera to interpret contemporary interiors through welcoming shapes and flexible configurations. The system includes upholstered poufs, armchairs and sofas that can be used individually or combined to create customized seating arrangements.
The defining feature of the collection is the distinctive design of its low backrests and armrests, characterized by an original saddle-shaped profile. This detail gives the seating a recognizable identity and makes Sadel particularly suitable for freestanding arrangements in the centre of a room.
Sadel seating features a plywood structure with shape-retaining polyurethane foam padding, density 25/40 rc. Adjustable non-slip feet provide stability and allow the seating to adapt to different floor surfaces.
The collection offers a wide selection of upholstery options, organized into the Essential and Sartorial ranges. Fabrics, faux leathers and genuine leathers provide extensive possibilities for tailoring each composition to the interior design project.
Versatility is central to the Sadel collection. Rectangular and square poufs, armchairs and sofas with different backrest and armrest configurations can be combined to create linear or more articulated layouts for spaces of varying sizes.
These features make Sadel suitable for lounge areas, reception spaces, waiting rooms, hospitality interiors and shared environments. Its generous proportions and substantial upholstered volumes help create welcoming spaces while maintaining a clean, contemporary design language.
The Sadel system can be complemented by a painted metal side table featuring a circular top measuring 25 cm in diameter, and a multifunction power column equipped with one DE electrical socket, one USB-A port and two USB-C ports.
Both accessories are integrated through concealed fixing systems and are available in black, charcoal, white, stone grey and brown finishes.
Combining modularity, comfort and functional accessories, Sadel offers a versatile seating system designed to meet the changing needs of contemporary interiors.
