'a support to the mattress' is the definition.
I can't tell whether this defines the answer.

'society girl back to place' is the wordplay.
'society girl' becomes 'deb' (I've seen this in other clues).
'back' says the letters should be written in reverse.
'to place' becomes 'stead' (synonyms).
'deb' written backwards gives 'bed'.
'bed'+'stead'='BEDSTEAD'

Can you help me to learn more?

(Other definitions for bedstead that I've seen before include "Frame for a sleeping person" , "Frame upon which a mattress sits" , "Frame etc on which one sleeps" , "Framework supporting a sleeper" , "Framework supporting springs and mattresses" .)
