The living room of former Domino editor, Sara Ruffin Costello, has been a longtime favorite of mine. And when it came to planning my sister's awkwardly laid-out living room with its off-centered fireplace, the layout of Costello's room immediately popped into mind. The solution seemed to lie in a single piece of furniture: the flat daybed. Because it doesn't have a backrest, it keeps the room open rather than breaking it up, and it allows for either two seating areas or one large grouping. In my search for an affordable option, it seems most flat daybeds are the designer's own version of Ludwig Mies van der Rohe's famous Barcelona daybed, complete with bolster headrest. And while most cost upwards of $1000 (the Barcelona topping the list at a steep $8k), I discovered that one of Ikea's newer "designer" items is a white, leather daybed retailing for $499. Perfect.
