Tanso 2-Seat Sofa

Designed by David Irwin, the Tanso 2-Seat Sofa brings a refined, architectural approach to modern outdoor furniture. Inspired by the simplicity of Japanese design, Tanso focuses on proportion, material honesty, and craftsmanship rather than excess. Constructed from solid teak, the frame is naturally weather-resistant and built to age beautifully outdoors, while the elevated detailing gives it the presence to work just as well inside. This is sustainable outdoor seating designed with intention—calm, balanced, and made to last.

Sized for smaller patios, terraces, or indoor living spaces, the Tanso 2-Seat Sofa works seamlessly as part of the wider Tanso collection or mixed with other teak outdoor furniture for a more layered look. The breathable grey outdoor cushions are comfortable, easy to maintain, and designed for everyday use, whether you’re creating a relaxed alfresco lounge or an indoor-outdoor living room that blurs the line between the two. It’s a versatile foundation piece that reflects Irwin’s curiosity about how things are made—and why they endure. Built to last, the Tanso 2-Seat Sofa is a long-term investment in both your space and a more sustainable way of living. Available at Comosum.
