The Unopiù Treble Sofa 146 cm – the 2-seater sofa of the modular Treble system for terraces and lounge areas.
The Treble Sofa 146 cm is the heart of many Treble configurations: wide enough for two people, compact enough for smaller terraces. Aluminum frame in graphite, sage, syrah, or sand, polypropylene rope weaving in mottled white – the same design language as the armchair and corner modules, just wider. 146 cm that can be integrated into any lounge composition.
The aluminum frame is permanently weather-resistant, the PP rope weaving is UV-stable and easy to care for. No winter storage, no special treatment. At 30 kg, the sofa is stable and sturdy, yet still manageable. The seat height of 42 cm corresponds to the lounge level of all Treble modules – perfect combinability without height differences.
The sofa is delivered without cushions – suitable upholstery sets (Nuvola white, various acrylic colors) are available separately and are custom-made for the Treble seating surfaces. The choice of upholstery allows for individual color design of the lounge.
The Treble Sofa 146 cm can be combined with the Treble Lounge Chair, the Treble Coffee Table with a solid teak top, as well as chaise longue and corner modules. The entire Unopiù range can be found in the shop.
