Meriva A rear head restraints

[Dld]

Hi. New to the group, and wonder if anyone can help me.  I have bought a 2010 series A Meriva Design,  and have just realised the rear head restraints are missing. I am not sure whether they are Black or Charcoal. Does anyone know where I can find replacements at sensible cost? Do they have to be Meriva specific or are other models the same? Many thanks in advance.
