One is enough.

Have you seen anything square that you like?

I have seen a few square but wasn't sure what the dimensions should be. Any recommendations?

All of the walk spaces are way too small. Just try wakling into a space in a less than 2' space . IMO get the main pieces installed and then decide on the coffee table and when you have done that part post pics of the space . I will say that often what works on paper does not work in real life .If this is already a room post pics of the space . IMO rugs tables and window treatments are the last thing to choose so my advice slow down and do this right the first time

Not enough walking around space.

I think a round coffee table would be a better option for you.

42" round or square.

Two coffee tables would be too much. Since you are repeating square shapes in all your furniture, I would suggest introducing a round coffee table. Maybe look into oversized round, nesting coffee tables.

Your two coffee tables might work really well but it's hard to say without seeing the actual furnishings in the room.

Hi Holly, would you consider sharing a pic of your couches? I'm looking at getting a custom couch in Jango Snow, I have a small swatch but would love to see what it actually looks like on a large couch...
