Sleep Number has put its efforts toward expanding its basic air-mattress concept since 1987. They invented a way to customize mattress firmness for every customer, and then added higher-quality materials and electronic innovation. Next, they developed ways to track sleep quality through the night and designed a mattress to adapt to those changes in real-time. All the while, Sleep Number has pushed the mattress industry towards understanding sleep and pushing customers to pursue more restful nights.
