ABOUT CASPER
Casper was created to re-imagine sleep from the ground up, beginning with its obsessively engineered, outrageously comfortable mattress. All of Casper's sleep products are developed in-house by the company's award-winning R&D team.
Casper was recently named one of Fast Company's Most Innovative Companies in the World and its eponymous mattress was crowned one of TIME Magazine's Best Inventions.
FAQs
What is the 120-Night Trial?
We believe you should actually sleep on a product to decide if you like it. So we give you 120 nights to test out all Casper products in your own home. If you don't love it, we'll give you a full refund.
Why does the Casper need a foundation?
The foundation helps support the Casper while optimizing air flow to ensure a restful night's sleep.
Can I put the foundation on the floor?
We do not recommend putting the foundation directly on the floor as doing so can cause wear to the chambray cover.

It works. It’s nice that it comes apart for moving. It’s kind of heavy and is largely just wood covered with fabric. Raw, unsanded wood corners are threatening to poke out of the decorative fabric cover, which doesn’t thrill me.
