Single, pocket-sprung mattress, very good condition (East Hendred OX12)

This is a standard sized, single bed mattress that was originally one of a pair (it has a discrete zip down one side for this purpose, no redundant). Although it is quite a few years old, it is in very good condition. Apart from the fluffy bit covering one of the buttons (2nd row from the top), I can't see any marks of any sort. My wife, who is very light, has taken very good care of it. There have definitely been no 'accidents' on it! It has four carrying handles with vents on each side. The label says 2000 springs which I think is for the two mattresses combined so this single would presumably have 1000 individual pocket springs. It has a fire safety label shown in the photo.
