013 Osa Outdoor Dining Chair
Made from heat-treated pine able to withstand the harshest environmental conditions, the 013 Osa Outdoor Dining Chair by Henrik Tjaerby is explicitly functional and purposefully elemental. Designed to accompany the Osa Outdoor Table, it shares the same distinctive proportions and seating planks.
With its grounded stance and broad surfaces, the Osa is a timeless example of outdoor chair design—robust enough to endure seasons of weather and use. Its understated form and solid construction make it one of those rare low profile outdoor chairs that combines presence with subtlety. A reliable companion for long days outside, this outdoor wide chair is built for life outdoors, summer after summer.
Made in Finland of Finnish pine.
The Osa low profile outdoor chairs are made from heat-treated pine, Lunawood ThermoWood®. The heat treatment makes each outdoor chair weatherproof, requiring no additional surface treatment. ThermoWood reacts quickly to UV light and begins to shift toward a beautiful silver tone once unboxed. Your outdoor wide chair will reach its final colour after about a year outdoors. Pine is a soft wood and will get dents and bruises over time. But don’t think of them as flaws. Embrace them. They’re signs of life lived and furniture loved. Pine isn’t life-proof. It’s proof of life. All our products are locally made by select Finnish makers and specialists. Every pine tree is harvested from sustainably managed Finnish forests.
