One can view the patent on the earlier version. To my knowledge the model shown in the link in the preceding post has tension bolts attached to the top platform and extending downward, as a means of pre-loading the platform, which reduces the height and eliminates catastrophic unexplained buckling (collapse) of the internal elements which sometimes occurred in the originals. "Other Publications" cited on the first page gives a significant clue to the basis of design.
Some people like them. They look nice.
