That was us
And (as someone here noted) it was not an attempt to make a direct replica. We designed that for a client who wanted something with a similar vibe, but more streamlined (we even incorporated some hints of Kirk's TOS bridge chair for good measure.)
Hardcoated foam is probably the best way to go if you wanna recreate the curves of the original design. IIRC, there are stills from Jedi where you can see the foam coat wasn't even sanded all that much (some styrofoam beading was still visible in the finish) but that's movie magic for ya
Best of luck with the project.
