I still think that a square coffee table is appropriate

I've been looking at some photos this evening, and it seems the vast majority don't put any end table on the side that has no arm, but I found a couple that had round tables set off to the back a bit, and this very interesting set up

This seems to be typical.

Would love to see photos of your loft as you get it put together.

I also like the idea of a square coffee table, or even an ottoman to add some texture to the leather. Pick one with a size fitting with the size of the sectional. For example, I think the table in #1 that Marji found works well, but the coffee table in # 2 seems a bit large in proportion (perhaps rectangular would have been better?), and in # 3 it seems too small to be very useful. . Regarding a "table" for the chaise end, I like the little moveable table option in # 2 above.

And a loft with gigantic windows? This is going to be awesome to see!
