Comfortable, no doubt, but it makes Charlie cry! (5)

I believe the answer is:

couch

I'm a little stuck... Click here to teach me more about this clue!

'comfortable no doubt but it' is the definition.
I can't tell whether this definition defines the answer.

'charlie cry' is the wordplay.
'charlie' becomes 'C' (phonetic alphabet: alpha, bravo, charlie etc.).
'cry' becomes 'ouch' (I've seen this before).
'c'+'ouch'='COUCH'

'makes' acts as a link.

Can you help me to learn more?

(Other definitions for couch that I've seen before include "express" , "Long seat; grass" , "Upholstered seat for more than one" , "Sofa or settee" , "something comfortable to sit on" .)

I've seen this clue in the Evening Standard.
