Since launching online in 2014, mattress startup Casper has become one of the biggest disruptors in the industry. Customers can order the product online, have it delivered to their home in a box, trial it for 100 days, and return it if they don't like it.
It recently expanded its mattress range to offer more pieces — a queen-sized mattress, for example, can cost from $600 for a standard mattress up to $1,850 for a more technical piece.
The company's total revenue since inception reached more than $600 million in 2017, and it counts Target and 50 Cent among its investors.
