The Unopiù Treble Lounge Chair – Clean Lines, PP Rope Weaving, and Aluminum Frame for Timeless Outdoor Lounges.
The Treble Lounge Chair brings a formal consistency to the outdoor area that one would rather expect in contemporary living spaces: aluminum frame, polypropylene rope weaving in mottled white, 86 cm wide. Four color options – Graphite, Sage, Syrah, Sand – allow for precise coordination with the terrace architecture. In every variant, the armchair appears light, yet structured.
The aluminum frame is corrosion-resistant, UV-stable, and permanently suitable for outdoor use. The mottled white polypropylene rope weaving is weather-resistant, easy-care, and elastic – no winter storage, no special treatment. The armchair delivers what outdoor furniture at this price point must promise: durability without compromising on design.
With dimensions of 86 × 80 × 76 cm and a seat height of 42 cm, the armchair offers generous lounge comfort. The cushions are available separately (e.g., Nuvola in white, various acrylic colors) – this provides freedom in cushion design. Its weight of 20 kg makes it positionable without being too light.
The Treble Lounge Chair is part of a fully modular system: combinable with the Treble Sofa 146 cm, the Treble Coffee Table with a teak top, and other modules. You can find the entire Unopiù range in the shop.

Frequently Asked Questions about the Treble Lounge Chair
Is the Treble Lounge Chair suitable for year-round outdoor use?
Yes – the aluminum frame and polypropylene rope weaving are designed for permanent outdoor use. Both materials are corrosion-resistant, UV-stable, and weather-resistant. Winter storage is not necessary, but covering it during continuous rain will extend the lifespan of the cushions.
In what colors is the Treble armchair available?
The armchair is available in four colors: Graphite (dark grey), Sage (muted green), Syrah (deep red/burgundy), and Sand (warm beige). The color options apply to both the aluminum frame and the PP rope weaving.
Which cushions fit the Treble armchair?
We offer matching cushion sets: the Nuvola cushion in white and other color options in weather-resistant acrylic fabric. The cushions are available separately and are custom-made for the Treble armchair. Please specify which cushion combination you would like when ordering.
Can the Treble armchair be combined with other modules?
Yes – the Treble armchair is part of a fully modular system. It can be combined with the sofa, chaise longue (left/right), corner module (left/right), and the coffee table with a teak top to create individual lounge configurations. All modules share the same frame geometry and weaving.
