I have posted and deleted my ideas 3 times. I’m having trouble with the rug. Is it my monitor? I see yellow and green undertones and no correlation with your walls and sofa, so I am suggesting these Durable pillows from etsy.com to tie in what I see. One idea…between the two chairs, something with a hint of the nail head sheen and a matte gray body would work. Love this little table…on sale at Wayfair for $90.00 and the body of the table is a faux shagreen.

I think it is a bit of overkill to have both, especially since they tend to hang out in matched sets. It depends on what kind of entertaining you do. If your guests are likely to turn up the music and need some space to dance, then the coffee table would be in the way. Even if you think you need end tables because you want to increase your lighting with lamps, you can put a pair of matched floor lamps at each end of the sofa and use a coffee table. If you're likely to need extra seating more often than a surface for drinks, an ottoman that can be topped with a tray or used for seating might be best. If your style is very formal to antique, then all three tables might work for you. Be sure end tables arrive 1" above or below the sofa's arms. When topped with lamps, the lamps should reach 58-64" above the floor. Coffee tables should be 12-18" from the seating to be useful, and arrive 1" above or below the sofa seat. Keep it within 2/3 of the sofa's length and half its width.

There is so much space, a coffee table is a fantastic idea, and an end table is the best alternative in congested places.
