Ilmari Tapiovaara
1914–1999
Finnish designer who built chairs under wartime shortage conditions and never lost the habit, which is why they stack, travel and survive.
1898–1976
Finnish architect who patented a way of bending laminated birch, then used it to make furniture that has stayed in production for ninety years.
Why they matter
Aalto qualified as an architect in Helsinki in 1921 and worked at building scale for the rest of his life, but the furniture came out of a specific complaint. Tubular steel was the modern material of the early 1930s and he found it cold. He patented a method of bending laminated birch in 1933 and built chairs, stools and trolleys from that instead.
In 1935 he founded Artek with Aino Marsio-Aalto, Maire Gullichsen and Nils-Gustav Hahl to manufacture and sell the work. Stool 60, the Paimio chair and the 403 armchair all date from that first decade and Artek still makes them.
That continuity is the buying question rather than the attribution question. Nobody doubts who designed a Stool 60. What separates a 1930s example from a current one is the label, the birch and eighty years of wear.

What to look for
Marks, editions, patina and production partners — fact-checked for this designer.
- These designs have never gone out of production, so the real question is which decade an example belongs to, not who designed it.
- Artek used paper labels and underside stamps that changed over the decades and they are a genuine dating aid, but no public Artek reference chart is easy to come by, so treat a dealer's decade claim as a claim.
- Early birch is denser and warmer in colour than current stock and the leg-to-seat joint on a prewar Stool 60 sits differently from a modern one.
- The 403 armchair was designed around 1931 to 1932 for the Paimio sanatorium and has been made ever since, so a 1932 date on a listing needs evidence beyond the model number.
