by Quick answer: Casper offers a 100-night mattress trial that begins on delivery. You must sleep on it for at least 30 nights before requesting a return, then returns are free with a full refund anytime through night 100.

Casper Trial Period: The Honest Verdict
Casper's 100-night trial is straightforward but has one catch worth knowing: a mandatory 30-night adjustment period before you can return. The reasoning is that bodies take time to adapt to a new mattress. After night 30 and through night 100, returns are free, handled by a courier, and refunded in full.
If the trial is not going well, our Casper alternatives guide breaks down better options by sleeper type.
What We Could Verify
| Item | Detail |
|---|---|
| Trial length | 100 nights, starting on the delivery date |
| Break-in rule | Must keep the mattress at least 30 nights before returning |
| Return process | Free courier pickup; no need to rebox; refund to original payment |
| Warranty | Separate 10-year limited warranty on mattresses |
What Owners Actually Report
Most of the friction owners describe is about the fine print rather than the refund itself. Returns are generally smooth once the 30-night window passes, and refunds post within about two weeks. Watch-outs: setup-service fees aren't refunded, bundles share the mattress's 100-night window with no partial returns, and third-party purchases follow the retailer's policy instead. For exact, current terms always confirm on Casper's official trial page.
The Saatva Take
Casper's 100 nights is a fair window, but it's modest next to the longest trials available. The Saatva Classic offers a full 365-night trial, giving you over three times as long to judge the fit, plus a lifetime warranty and free white-glove delivery. The trade-off is a flat $99 return fee versus Casper's free pickup, but you get far more time to decide.

Bottom Line
Casper's trial is honest and easy once you clear the 30-night break-in, with free returns through night 100. If trial length is your priority, a 365-night option like Saatva gives you much more room to be sure. For the latest policy details, check Casper's official page.
Bottom line: Casper's 100-night trial is solid, but the 30-night break-in is the rule most buyers overlook.
