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.

Simple to assemble after trying
Simple to assemble after trying a couple of times as there wasn’t instructions in the box. The mattress support boards did not lie flat since the middle support beam sat a fraction higher than the edges. I actually need one that is half that height as my bed frame sits fairly high, so I need to hop up to get on.

This foundation exceeded my expectations. I used the white glove service and noted that it went together fairly easily and the best part was it appears to be breathable.

Like everything you assemble on
Like everything you assemble on arrival, the instructions were written for another model. So a little common sense and more time than I expected was needed. But it is assembled now and just fine. In my next life, I plan to become an instruction writer.
