We're also thinking that we'd get rid of our super long Ikea coffee table (that I bought right after I graduated college) and replace it with an ottoman that has storage capabilities. You can see the extra long table in action here:
We also have these great mid-century side tables (handed down by a family friend) on either side of the sofa set that I would love to keep in the room (if they'll fit on either side of the sectional we end up getting).
The sectional will be the thing that sets for tone for the room, so we'll probably get that before we make any other purchases for the space.
