After this first step I gently opened all the loose joints of the other chair and started sanding the wooden pieces. Under the dark brown varnish I discovered this really nice light coloured wood which looks much better and more natural & original. I'm planning to use oil wax to keep this original colour. I'm no expert with old furniture but for sure the result should be better than before.
Promise to post some photos as this project move on.
