Did you know?  

The old phrase “sleep tight” actually comes from rope beds used in the 16th and 17th centuries. Before spring mattresses, beds were made with ropes woven across wooden frames to support a mattress. Over time, the ropes would sag — so people had to tighten them regularly to get a good night’s sleep. Hence the saying, “sleep tight!” It was practical advice… not just a sweet bedtime wish.
