The Tanso 3-Seat Sofa is a generous, design-led outdoor sofa that balances robustness with quiet elegance. Designed by David Irwin, the piece draws from Japanese furniture traditions, focusing on clarity of structure and purposeful construction. Made from solid teak, the frame is highly durable and weather-resistant, while the refined joinery and proportions give it a sophistication rarely found in outdoor furniture. Crafted with teak, it's part of Case's commitment to sustainable, long-lasting outdoor living.

It’s equally suited to open gardens, covered terraces, or indoor spaces that call for relaxed, natural materials. With its wider scale, the Tanso 3-Seat Sofa anchors larger outdoor seating arrangements and pairs beautifully with other Tanso pieces or mixed teak furniture. The grey outdoor cushions are breathable, comfortable, and easy to clean—ideal for long afternoons outside or effortless indoor lounging. Designed to transition between environments, the Tanso 3-Seat Sofa embodies sustainable furniture principles through material longevity, thoughtful design, and everyday usability. Available at Comosum.
