Decides to have wooden seats (7)
I believe the answer is:
settles
This clue could be a double definition.
'decides' is the first definition.
('settle' can be a synonym of 'decide')
'wooden seats' is the second definition.
'settles' can be an answer for 'seats' (settle is a kind of seat). I'm not sure about the 'wooden' bit.
'to have' acts as a link.
Can you help me to learn more?
(Other definitions for settles that I've seen before include "Long wooden benches with backs" , "furniture" , "Becomes established in a place" , "Comes to rest" , "Pays the bill" .)
