Puzzle out this contraption of pleasure
This is a photograph of a chair identical to one found in the Marble Palace. Yeoli speculation is rife as to the precise purpose of the chair, though the Arkan term for it is best translated as 'multiple siege of coitus chair.’ Other terms translate as 'three-chair' or 'one, two, three,' implying use by one gentleman and two ladies.
But the technique of using this device is either a highly-guarded secret among Marble Palace denizens, else simply lost to the vicissitudes of confidentiality and time.
In what precise configuration, the intrigued scholar wonders, do the parties arrange themselves upon it?
We encourage all speculations, as the reader providing the most plausible solution will be covered with everlasting glory. Diagrams and photoshops are particularly welcomed.
