I think these first two chairs would be comfortable to sit in, I would even keep the upholstery the same, circa 1950.
I love the backs of the second chairs, it's different than what you would first think of to recover.
And these ladder chairs, circa 1900 are chairs I've been looking out for these as well.
And look at these head and foot boards aren't they wonderful ? You would have to have a big room to put these in I can just imagine a room with these it would be beautiful.
