by Quick answer: Casper gives you a 100-night sleep trial on mattresses bought directly from Casper. You must sleep on it for at least 30 nights before you can return it. After that, returns are free — free pickup, no return fee, no restocking fee — and you get a full refund anytime through night 100. The mattress also carries a 10-year limited warranty against manufacturing defects.

How Casper's 100-Night Trial Works
The trial clock starts the day your mattress is delivered. Casper requires you to sleep on the mattress for the first 30 nights before a return request will be approved. The reasoning: foam needs time to decompress and your body needs time to adjust to a new feel. Returns initiated before night 31 are typically declined.
From night 31 through night 100, you can return the mattress at any point. The trial applies only to direct Casper purchases — from Casper's website or Casper retail stores. Buying through Amazon, Costco, or another third-party retailer means that retailer's return policy applies instead. Soft goods like pillows and sheets have a separate 30-day window, not 100 nights.
Check Casper's site for current terms, as fine print can change.

How to Return a Casper Mattress: Step by Step
Once you have passed night 30 and you are still inside the 100-night window:
- Contact Casper. Start the return through Casper's official returns page or customer service. Have your order number ready.
- Schedule pickup. Casper arranges free pickup — typically through a local charity or furniture recycler. You do not need the original box or any packaging.
- Condition check. The mattress must be in donatable condition. Heavy staining or significant damage can cause a return to be refused. A mattress protector used from night one avoids this entirely.
- Pickup happens. The team comes to your address and removes the mattress. You do not carry or repackage anything.
- Refund is issued. After pickup is confirmed, Casper processes your full refund. Allow roughly two weeks for the credit to appear, though timing varies by payment method. Promotional discounts applied at checkout do not reduce the refund amount.
What's Refunded — and What the Warranty Covers
A successful return inside the 100-night window gets you a full refund of the purchase price. Casper's 10-year limited warranty is separate from the trial: it covers manufacturing defects such as sagging beyond a specified threshold or broken components under normal use. The warranty is non-transferable, so it does not follow the mattress if you sell it. Damage from misuse, improper foundations, or normal wear is not covered.
For return purchases from retailers, the warranty terms may still apply through Casper directly — but the trial and refund route goes through the retailer. Confirm with Casper's support team if you are in this situation.
If you want a longer runway to make up your mind, Saatva's Classic comes with a 365-night trial and a lifetime warranty — though Saatva charges a flat $99 return fee. See our full Saatva mattress review for the full breakdown.

FAQ: Casper Return Policy
Is there a return fee for a Casper mattress?
No. Returns on mattresses bought directly from Casper are free. Casper covers pickup and does not charge a return or restocking fee. You get a full refund of the purchase price.
How long do you have to return a Casper mattress?
100 nights from the delivery date, for direct purchases. The window does not extend past night 100 under any circumstances, so do not wait until the last few days to decide.
What is the 30-night rule?
Casper requires you to sleep on the mattress for at least 30 consecutive nights before filing a return. The idea is to give the foam time to break in and your body time to adjust. Returns requested before night 31 are typically not approved.
How long does a Casper refund take?
Casper processes the refund after the mattress is picked up. Most customers see the credit within about two weeks, though it depends on your bank or card issuer. Check Casper's site for the most current estimate.
How long is the Casper warranty?
10 years. It is a limited warranty covering manufacturing defects under normal use. It is non-transferable and does not cover damage from misuse, improper bed frames, or regular wear over time.
I bought my Casper on Amazon. Can I return it through Casper's trial?
No. Third-party purchases — Amazon, Costco, and other retailers — fall under that retailer's return policy, not Casper's 100-night trial. Contact the store where you bought it to understand your options.
Bottom Line
Casper's 100-night trial is straightforward: buy direct, sleep on it for 30 nights, then return anytime before night 100 for a free pickup and full refund. The 10-year warranty adds coverage after the trial ends. The main catches are the 30-night break-in requirement, the donatable-condition rule, and the fact that retailer purchases are outside the trial entirely. Always confirm current terms on Casper's returns page before you start a return.
