I would start by steam bending each segment to the final shape, or as close as possible. The tiny strip, I assume is an accent strip, would be bent and glued to each segment. I would then bevel, fit and glue each segment to each other. The final shape would then be refined by sanding and sculpting. The upholstry I would leave for someone with such skills. The metal work is a no brainer.
Why would someone build one like this? Because it could bring many thousands of dollars and prestige.
