This Wycombe museum will tell you all you need to know about the local history. Presumably, they also had a chair surplus in the area and wanted to put it to good use.
It brings to mind those shops that are clearly run by a husband and wife team with no regard to whether their respective products are remotely related: Knitwear and car parts; chemists and fishing tackle, pipe cleaner modelling and wig maintenance.
Wycombe Local History and Chair Museum focuses on Windsor chairs. For those of us with broader chair tastes, this is something of a disappointment.
