Extremely sensitive judoka provides chair (5)
I believe the answer is:
sedan
'chair' is the definition.
(sedan chair is a type of chair)
'extremely sensitive judoka' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'sensitive' becomes 'sore' (as in a sore wound).
'judoka' becomes 'dan' (both can mean a judo expert).
'sore' with its centre removed is 'se'.
'se'+'dan'='SEDAN'
'provides' acts as a link.
(Other definitions for sedan that I've seen before include "Where Prussians defeated French" , "big chair" , "Palanquin; car" , "Chair used as transport" , "Saloon car in America" .)
