What sort of door 'closer' do I need to prevent a back door banging
closed?

It's just a plain[ish] solid wooden door that closes with a bang and a
rattle if you close it at all carelessly. Unfortunately the bang and
rattle disturb the bedroom above, so we're looking for something that
will slow down the final closing.

Thus we're not looking for something that always closes the door, in
fact if it's left open we probably want it to stay that way, what we
need is a 'damper' for the last few degrees of closure.

Is there a specific name for this sort of thing?
