Material providing end of bed with a covering (6)
I believe the answer is:
damask
'material' is the definition.
(damask is a kind of material)
'end of bed with a covering' is the wordplay.
'end of' indicates one should take the final letters.
'with' means one lot of letters go next to another.
'covering' becomes 'mask' (mask is a kind of covering**).
The final letter of 'bed' is 'd'.
'd'+'a'+'mask'='DAMASK'
'providing' acts as a link.
(Other definitions for damask that I've seen before include "Figured material" , "Heavy embroidered linen" , "Red" , "heavy embossed table linen" , "Silk or linen material woven with pattern on either side" .)
