Very drunk, run into item of furniture (9)
I believe the answer is:
bladdered
'very drunk' is the definition.
'run into item of furniture' is the wordplay.
'run' becomes 'ladder' (both can mean a rip in tights).
'into' indicates putting letters inside.
'item of furniture' becomes 'bed'.
'ladder' put within 'bed' is 'BLADDERED'.
(Other definitions for bladdered that I've seen before include "Drunk (slang)" , "Well away" .)
