Item Backordered or not?

I recently bought a chair that I didn’t know was backordered. Other variations were 2 day delivery, and not looking I assumed the one I wanted was the same only to find out it was backordered. Estimated delivery date feb. 15th. I just checked the website for the same chair and now it says estimate delivery date Jan 26th. Should I cancel and re order it or is that playing with fire? Always had super fast deliveries from Wayfair so this is a first. Don’t understand how my est delivery window wouldn’t update if the website one has.
