Posh bed for accommodating posh blogger (4-6)
I believe the answer is:
four-poster
'posh bed' is the definition.
'for accommodating posh blogger' is the wordplay.
'accommodating' means one lot of letters goes inside another.
'posh' becomes 'u' (abbreviation for upper-class - opposite to non-u).
'blogger' becomes 'poster' (a blogger is someone who 'posts' online).
'for' going around 'u' is 'four'.
'four'+'poster'='FOUR-POSTER'
(Other definitions for four-poster that I've seen before include "Large bed" , "Type of bed" , "Imposing item of bedroom furniture" , "Canopied bed" , "Curtained bed" .)
