Casper gives a 100-night trial on mattresses, with a mandatory 30-night adjustment period at the start. Casper will not accept a mattress return before night 30 — the policy exists because foam beds feel noticeably different in week one than in week five.
FREE AFTER 30 NIGHTS. Once the adjustment period is over, Casper describes returns as free and easy. You are not expected to repackage the mattress.
THE BEDDING TRAP. Casper pillows and bedding do not share the mattress trial. They run on a separate 30-day return window. Buyers who order a mattress-plus-pillow bundle and try to send everything back on night 70 find the pillow is long out of window.
HOW TO START. For large items such as a mattress, Casper routes you to a returns specialist — start a chat on Casper's site or use the email link in the help centre article on starting a return. Have your order number ready.
WHAT IS NOT PUBLISHED. Casper's help articles do not spell out refund timing, and the treatment of clearance items and adjustable bases is not detailed in the policy text we verified. Confirm those directly if they apply to your order.
PRACTICAL ADVICE. Mark night 30 and night 100 in your calendar the day the mattress arrives. The gap between them is your whole decision window, and the most common way people lose a refund is simply forgetting the deadline.
