Parts of bed are in front of tables (10)

'tables' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'parts of bed are in front' is the wordplay.
'parts of' is an anagram indicator.
'are' becomes 'a' (the 'are' is a metric unit of area).
'in' is an insertion indicator.
'front' becomes 'hoards' (I am not sure about this - if you are sure you should believe this answer much more).
'bed'+'a'='beda'
'beda' is an anagram of 'eadb'.
'eadb' inserted inside 'hoards' is 'HEADBOARDS'.

'of' acts as a link.

Can you help me to learn more?
