So the question is:  is it safe to remove the center stile on an upper cabinet?
I hate that divider but was worried it might be needed from a structural perspective.  

After re-reading, you're asking about removing the stile on an upper cabinet?

A lot of factors go into that decision. Cabinet width, and construction mainly.


Figuring out how to do something you have never done is what makes a good challenge.
