How are Casper mattresses delivered?

Casper mattresses are compressed, rolled and shipped in a compact box. They typically arrive within three to five business days after leaving the warehouse.

How do you unbox a Casper mattress?

To unbox a Casper mattress-in-a-box, you simply pull it out of the packaging and lay it flat. It will expand over several hours before it is full. It is totally normal for your mattress to appear a bit lumpy as it opens up.

Do I need a Casper foundation?

Casper mattresses are designed to work on a firm, solid foundation that can support the full weight of the mattress and the user. A Casper foundation is basically a wooden box with slats across the surface and fabric on top. Foundations are designed to offer stronger support to ensure the longevity of memory foam mattresses.

Do I need to flip my Casper mattress? 

Casper mattresses are designed to be used on one side only, so you don't need to flip them.
