Does The Casper Mattress Require A Break-In Period?

No, your new Casper mattress doesn’t require a break-in period, but you should sleep on it for 30 to 90 days so your body can adjust to its firmness and overall feel.

Casper offers a 100-night trial for all of its mattresses. For most sleepers, that is enough time to test the new mattress and decide whether or not it’s the right fit.
