CSPR

Casper Sleep Inc

A maker of mattresses and sleep gear that helped pioneer the "mattress-in-a-box" trend, shipping compressed foam mattresses straight to people's doors along with pillows, sheets, bed frames, and even dog beds. Five founders launched it in 2014 to shake up a mattress industry they saw as confusing and overpriced. The name reportedly comes from an easygoing, sleepy college friend of the founders, though it also echoes the friendly cartoon ghost—fitting for a brand all about restful nights.
