Danes designed chair (5)
I believe the answer is:
sedan
'chair' is the definition.
(thesaurus)
'danes designed' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'danes' anagrammed gives 'SEDAN'.
(Other definitions for sedan that I've seen before include "Dean's in an old conveyance" , "Chair to be carried by two" , "Old portable chair for Danes" , "Where Prussians defeated French" , "In cars, an alternative name for 'saloon'" .)
