Few things will improve your life like getting a good night’s sleep. Problem is, while you can hit the lights and turn off the TV early, the wrong mattress will sabotage all your efforts. That’s why it’s time for the Casper mattress. Developed by a team of engineers with experience from IDEO, the Casper mattress offers a patent-pending sleep surface crafted from proprietary memory and latex foams, which allows Casper to sleep cool, provide bounce, and promote ideal anatomic support. No matter the size you choose, your mattress will arrive at your door in a small, “how did they do that?” sized box, and shipping is free to the contiguous U.S. and Canada. Not satisfied? Return it for a full refund within 100 nights. Each is manufactured and hand-stitched in America and ready to deliver the sleep you deserve. Plus use code “coolmaterial” for $50 towards a mattress through the end of the month (4/30).
