Coffee tables are typically around 18 inches tall, give or take an inch, though some are much shorter. I'd recommend setting it up in front of the sofa you intend to use with, or something it's height if it's too much trouble to bring it in for testing, and try it out for a couple days to see if it feels right. It sounds like it could be a very interesting coffee table.
Thank you so much, I'll do that.
Please share pictures if you decide to go ahead and use it.
you could always add some legs if it is too low.
