Sleepopolis is an editorial site dedicated to providing objective mattress reviews. In July 2017, we acquired Sleepopolis.com with Casper’s financial support. Derek Hales and Samantha Hales are no longer associated with Sleepoplis.com. We are funded by affiliate relationships with the products we review, which means we get a percentage of a sale if you click over from our site (at no cost to our readers). We are committed to transparency and editorial integrity.
