1950's - 1960's Piano chair in Wilkes Barre, Pennsylvania For Sale

This chair came with a piano we bought our daughter many years ago. when we bought it the chair was told to us buy the owner to be at least 40-50 years old - so now that puts it now about 50-60 years old. there are no manufacturers markings. the couple that we bought it from was from the UK and was heading back home. Not sure if from there or from the US. But unique. The chair portion as you can see slides in and out from the 4 different heights and has the storage in the bottom for the music sheets. Approx. 26" H x 24"w x 20" d at the furthest point of the arms. Approx. sitting area 18"w x 14" d. From what I can make out that the wood is possible "Maple or Oak". Planned on refinishing but now it just takes up room in my house and needs a new one!
