Thanks for posting! It sounds like your room has a lot of darker and heavier colors going on. I’m not sure about the wall color, but I think you couldn’t go wrong with bringing some lighter elements with the rug and coffee table to balance out these dark colors.
For the coffee table, I really like the glass option. A thin or lighter wood option could also look nice, with some gold accents on top. For the rug, my instinct says a white rug with a gray design could really fit nicely. Something like this rug would pull everything together and also break up all of those dark colors going on.
If white isn’t quite what you’re going for, a light gray or other neutral would also be nice!
