The Financial Post reports in its Saturday edition that over the past decade, there has been a mattress revolution that has changed the way consumers shop for their good night's sleep. The Post's Mirjam Guesgen writes that in the early 1990s, buying a mattress meant weaving your way to the back of a store and picking one out from less than a handful of options. "You'd walk right through that furniture store and in some ugly section in the back were the mattresses," said Stewart Schaefer, Sleep Country Canada chief executive officer. The first shift in the evolution of the industry came when Sleep Country freed mattresses from those darkened corners and gave them their own store. "When we opened up 29 years ago we were the disrupters, although that wasn't the word that was used then," Mr. Schaefer said. The first increase in mattress types was aided by technological evolutions, such as memory foam, along with retail strategies that emphasized the value of a personalized sleep experience. Then came the bed-in-a-box transformation. In 2006, an inventor in the United States created a machine capable of compressing and rolling mattresses into a fraction of their original size. From there, the bed-in-a-box company was born.
