That is my ideal height for guitar & slightly lower for bass, but still within the same general criteriaNot necessarily true... Right wrist can be harder to keep straight if the bass is too high. Ideal height for me is actually just a little lower than when rested on my leg in seated position.
Any lower & it's awkward for my fretting hand, and higher & awkward for my picking hand--especially as I normally play bass with my fingers & not a pick
