HÅG Capisco model as used in Star Trek VI: The Undiscovered Country for the
bridge of the Excelsior.
To use this chair in Blender, from your project, select File->Append(or Link),
browse to this file, select Collections, and then HAG Capisco. The entire chair
and its parts is all completely and correctly parented - all of the moving
parts will rotate (or slide, in the case of the seat back) about the correct
axes (though you'll have to look at the hierarchy to know what part to rotate).
