5/4 poplar, sliced down to ~1/8" strips. laminated, wrapped, and clamped to forms.
10 separate laminated stretches. 1 of them could have been condensed but we didn't have long enough wood for a continuous run.
This is one of the few props I'be built that had to be constructed using almost the exact historical methodology. The couch is too open to hide any support framing or hardware. And with the amount of time it took to laminate everything I had my fingers crossed that it would actually fit together.
