Resting-places in the county (4)

I believe the answer is:

beds

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

'the county' is the definition.
(abbreviation for Bedfordshire)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for beds that I've seen before include "Pieces of furniture" , "Place" , "Hospital places" , "Garden plots - English county (abbr)" , "Places to sow or to sleep" .)

I've seen this clue in The Mirror.
