Casper believe sleep is the superpower that charges everything people do.We have spent years studying the magic and science of sleep. The more we learn the more we are sure. Great sleep changes everything. It makes us friendlier faster smarter even warmer and fuzzier. If we all got great sleep the world would be brighter.So we dreamed a big dream.We started by creating an outrageously comfortable mattress and shipping it to your door in a tiny box. Now over one million sleepers later our mission has only grown.
