Trybo armchairs by Edvin Helseth, made in Sweden in the 1960s, are rare design furniture. Good condition. Edvin Helseth, a Norwegian interior designer born in 1925, designed these armchairs as part of his series "Trybo" for Stanges Bruk in 1964. The Trybo series is distinguished by its square shapes and the use of wooden ankles without screws or glue. There is also a matching table and a bench available to complete the whole. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
