Designed to pair seamlessly with the Tanso Armchair, this cushion adds comfort while preserving the collection’s calm, architectural clarity. Expertly tailored for a precise fit, it features a supportive polyester filling wrapped in a UV- and mould-resistant Textilene cover, making it well suited for long-term outdoor use. Crafted with teak, it's part of Case's commitment to sustainable, long-lasting outdoor living.

Discreet toggle buttons secure the cushion neatly in place, ensuring it stays put without distracting from the clean teak frame beneath. In keeping with David Irwin’s approach to design, the Tanso Armchair Cushion is purposeful rather than excessive. It enhances everyday comfort while allowing the craftsmanship and material honesty of the chair to remain the focus. Used outdoors on a terrace or brought inside for an indoor–outdoor living space, it’s a simple, durable upgrade that aligns naturally with modern, sustainable outdoor furniture. Available at Comosum.
