Double Emma mattress (hardly used but some marks) (Mackworth Estate DE22)

This is an excellent and expensive mattress! My partner brought it with him when we moved in together and it's been on a spare bed. It's hardly been used, but does have some marks which will probably wash off. We need to turn the spare room into a study so it needs to go. Already sold the bed, and a family member wanted the mattress but changed their mind as the bed they had wasn't a proper sized double. More details then you need there...but someone please rehome this fancy mattress!
