HOME, JEEVES: If you haven't headed over to the corner of 14th and T streets N.W. to wander through Room & Board, you should put that on your list of Important Stuff to Do. The four-story home furnishings store is full of timeless, mid-century modern delights... but not everything Room & Board makes is in the store, no matter how glorious it is. Case in point: The Eos Swivel Chair ($999), a round little muffin of sitting delight, available in six neutral and natural colors. But hey, shopping online is always comfy, and you can go it without going out in 90-degree weather. GET IT: RoomandBoard.com.
