Frisky stars met in bed (8)
I believe the answer is:
mattress
'in bed' is the definition.
(I know that mattress is part of bed)
'frisky stars met' is the wordplay.
'frisky' is an anagram indicator.
'stars'+'met'='starsmet'
'starsmet' with letters rearranged gives 'MATTRESS'.
(Other definitions for mattress that I've seen before include "Palliasse" , "Bedding" , "Stuffed bag on which to sleep" , "Nap on this" , "For the smart set to lie on?" .)
