Will become hard to get a stand seat (6)
I believe the answer is:
settee
'seat' is the definition.
(I know that settee is a type of chesterfield)
'will become hard to get a stand' is the wordplay.
I cannot quite understand how this works, but
'hard' could be 'set' (similar in meaning) and 'set' is found in the answer.
'stand' could be 'tee' (I've seen this before) and 'tee' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for settee that I've seen before include "Multiple seat" , "Small sofa" , "chair" , "Chesterfield" , "Comfortable seat for two or more" .)
