We will be mounting our tv ASAP for our sons safety and my peace of mind. Here is my issue and I need input: we live in an apartment; so no cutting holes in the walls for cords. I also want it to look nice. This is our current wall and setup but its not safe for babies/kids and I spend half the day trying to keep DS away from the TV area.

What should I do underneath? Keep the black cabinet or something else? Mount a mantel?

I kind of like the look of this but not sure how realistic it is (second picture):

Any input is appreciated!!
