I recently moved from New York to a one-bedroom apartment in San Francisco and the list of friends that I’ve said “come and stay!” to has been growing and growing. The problem is I don’t like sleeper sofas—and while an air mattress is perfectly fine, there’s something very dorm-like about them. It’s a sad image: our guest—a parent or sibling or best friend—standing over me with a pillow in hand as I unfurl the plastic and start up the blower. That’s not the kind of host I strive to be. Instead, I’d rather have a grown-up guest bed; a wood daybed in the corner of the room that expands into a proper bed for the night—and gets put back together in the morning. No air blower needed.
