Few things are sweeter than memories of nights spent away from home at summer camp, or at friends’ houses where we got to sleep in the extra bunk. There was a sense of adventure inherent to falling asleep so high off the floor, drifting off in the midst of a conversation with a friend we could hear but not see. The top bunk was always the preferable of the two, even though it required a bit of dexterity to navigate one’s way in and out of it in the dark for a middle-of-the-night glass of water or trip to the bathroom. And bunk beds still stand strong today, carrying on with the sleepover tradition in various styles — some classic, some whimsical, with one or two over-the-top accessories (see: sliding board) we would’ve flipped over back when we were small enough to fit. With kids’ beds like these, “lights out” is actually something to look forward to.
