The interior designs of all Treks were largely decided upon for reasons of practicality with an eye towards "contemporary" standards of the day. They wished to appear forward thinking but relatable to audiences of their respective days. Nothing laughable about that. And, as I stated earlier, even in retrospect the "look" serves a valid function in providing a contextual framework. The 60s look of TOS helps cue us, for example, to be forgiving in their attitude towards women. Though I will say TNG was not as advanced in terms of how they depicted women as they should have been. I would also confess to finding terms such as "laughable" to be wrong and offensive. Offensive because I view the artisans and technicians who did the best they could do in providing a real and plausible backdrop for the story to inhabit. No matter what the age or era these folks should be hailed and their efforts never derided by disdainful laughter.
