Americans like their beds like they like their steaks, big. The California king bed was created sometime during the the 1920s or ‘30s as a glamorous mattress large enough to bed the big-name celebrities of Hollywood. The Eastern king-sized bed (aka simply the king bed) became standard after World War II because it was the exact size of two extra-long twin box springs.
Along with sleeping in ridiculously large beds, Americans also love their televisions and their gadgets. More than half of Americans recently polled by the National Sleep Foundation report watching television and/or using a computer or tablet within the hour before bed.
