Here's a cushy one for you, but it may hold you up! (6)
I believe the answer is:
pouffe
'here's' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pouffe that I've seen before include "Solid cushion" , "Large firm cushion used as footstool or seat" , "Low stuffed seat or footrest" , "Cushioned seat" , "Thick cushion used as a seat or footstool" .)
