Odd features of chairs for vehicle
I believe the answer is:
car
'vehicle' is the definition.
(car is a kind of vehicle)
'odd features of chairs' is the wordplay.
'odd features of' means one should take alternating letters (letters in odd-numbered positions).
The alternating letters of 'chairs' are 'CAR'.
'for' is the link.
(Other definitions for car that I've seen before include "4-wheeled vehicle" , "Railway carriage; vehicle" , "Motor vehicle" , "Private vehicle" , "Auto" .)
