Make one's home chair less soft (6)
I believe the answer is:
reside
'make one's home' is the definition.
(residing is a kind of making one's home)
'chair less soft' is the wordplay.
I cannot quite understand how this works, but
'chair' could be 'side' (side chair is a kind of chair) and 'side' is found within the answer.
The remaining letters 're' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for reside that I've seen before include "Live (in a place)" , "Live (at an address)" , "Dwell - settle" , "Stay - desire (anag)" , "Desire (anag) - to live" .)
