Brass & Glass

Love the coffee table but I think a round one would work better

If you're looking for something on wheels, I recommend a wooden side table with a black frame that can also be used for storage. It keeps the space flexible and still looks good with darker coffee table. This is from Arrtle furniture, and it's been really useful for living rooms.

The style of your table might be consider British Colonial & it doesn't really work with that lovely sectional. The table is just to bulky and heavy in it's details. I would not be looking for end tables to match or coordinate.

Are you sure you don't want to consider an ottoman/table? You're watching TV in this room. Certainly someone will want to put their feet up. This solves two problems.

What are the end tables for? To hold lamps? I think your room needs a floor lamp.

Everything is so big and square, some curves would add a nice texture to the room.
