Dining chair in massive pine by Edvin Helseth, 1964 for Trybo Furniture. Made in Norway.
The "Trybo" series was designed in 1964 for the "Trysil-cabin" (Trysil is a Norwegian ski-resort). Significant for the Trybo furniture is the square shapes and that no screws or glue are used; only wooden plugs. The freely shaped backrest is rotatable..
