Have you ever wondered why we say, “Sleep tight!” before nodding off? Despite how it sounds, it has to do with the evolution of the bed, not the quality of a bedtime tuck.
From the beginning of history, humans have slept on piles of, well, anything, to put some distance between themselves and the critters below. Today’s feet-warming, body-contouring beds have come a long way from the piles of hay and feathers our ancestors once snoozed on.
Check out the video above, created in partnership with Sleep Number, to learn more about the ever-evolving history of the bed ― as well as its future.
Just like diet and exercise, sleep is unique to each person and important for optimal health. Sleep Number® beds adjust on each side to your ideal level of firmness, comfort and support — your Sleep Number® setting. And when you add SleepIQ® technology you’ll know what to adjust for your best possible sleep.
