Casper is a global sleep company that launched in 2014 with one perfect mattress sold directly to consumers — eliminating commission-driven, inflated prices. Its critically acclaimed sleep surface was developed in-house, has a sleek design, and is delivered in a small, "how did they do that?"​-sized box. The company is one of the fastest growing consumer brands of all time, and its product line has increased to include sheets, pillows, a matching foundation, and a dog mattress. Casper was named one of Fast Companys 50 Most Innovative Companies in the World, and its eponymous mattress was crowned one of TIME Magazines Best Inventions of 2015.
