Designed by David Irwin, the Tanso Lounge Chair brings the same calm, architectural clarity of the Tanso sofa range into a more compact, flexible form. Inspired by the simplicity of Japanese furniture, the design emphasizes proportion, material honesty, and purposeful construction. Crafted from solid teak, the frame is naturally weather-resistant and built for longevity outdoors, while its refined detailing allows it to transition effortlessly indoors. This is modern outdoor furniture that feels intentional rather than decorative—designed to age well and be used daily. Crafted with teak, it's part of Case's commitment to sustainable, long-lasting outdoor living.

The Tanso Lounge Chair works beautifully as a standalone piece or paired with the Tanso 2-Seat and 3-Seat Sofas for a cohesive outdoor lounge setup. It also mixes easily with other teak outdoor furniture, making it a versatile addition to patios, terraces, or indoor-outdoor living spaces. Finished with breathable grey outdoor cushions that are comfortable and easy to maintain, the armchair offers relaxed seating without sacrificing structure. True to Irwin’s design philosophy, it’s a piece defined by how it’s made—and how naturally it fits into everyday life. Built to last, the Tanso Lounge Chair is a long-term investment in both your space and a more sustainable way of living. Available at Comosum.
