Noun
[...]
(organic chemistry, physical chemistry) One of two possible conformers of cyclohexane rings (the other being boat), shaped roughly like a chair.
A cyclohexane in chair conformation can be simply called a chair as a noun! I did not make this edit, it was added all the way back in 2009 by a user called equinox, and received 133 upvotes from the Wiktionary community.
