I've been doing some work for a family friend alongside my brother and the Lady we've been doing the work for recently moved house. She no longer has room for a set of 4 chairs plus a foot stool so she gave them to us to try and sell.
From what she's told me they are from the 1930's - but I know next to nothing about antiques and hence cannot verify the validity of this statement.
What I do know, is that the seat cushions are actually removable from the chair itself. They unfortunately have been left somewhere to get damp so the wood has split and whatnot, I don't intend to complete the restoration work myself so a lower value is expected.
Pictures are below, the four chairs would appear identical, these are all pictures of 1 of the 4:
