Casper's 100-night trial is well-known, but the fine print - 30-night break-in, soft-goods exclusions, third-party retailer rules, and donation-only returns - is what actually determines whether you'll get a refund. Here's how the policy works in 2026.

Casper offers a 100-night home trial on every mattress sold direct from casper.com - but the policy is more nuanced than the marketing tagline suggests. There is a mandatory 30-night break-in window before a return can be filed, separate 30-day rules for soft goods like pillows and sheets, and important fine print for bundles and third-party purchases.
This guide walks through exactly how the policy works in 2026, what conditions can void it, how refunds are processed, and how Casper's return terms compare to other major bed-in-a-box brands.
The 100-night trial starts the day your mattress is delivered. During the first 30 nights Casper requires you to actively sleep on the mattress so your body can adjust - returns filed before night 31 will be declined and you'll be asked to keep using it. After night 30 and up to night 100, you can start a return for a full refund at no cost.
A few details that aren't on the marketing page:
The 100-night trial only covers mattresses. Other Casper products follow a 30-day return window, and a few categories aren't returnable at all.
Pillows, sheets, and mattress protectors (per Casper's help center) must be returned within 30 days, unused and in original packaging. Once opened or slept on, these items are non-returnable for hygiene reasons and are instead covered by Casper's one-year warranty against manufacturing defects.
Bed frames and furniture are returnable within 30 nights of delivery - extended to 100 nights if purchased alongside a mattress in the same order. Frames must be disassembled and in donatable condition.
Bundles must be returned as a single unit. If you bought a mattress + frame + pillow bundle, you can't keep the frame and return only the mattress for a full refund - the entire bundle is returned together, or none of it.
Once your return is approved and the item is picked up or dropped at UPS, refunds are credited back to the original payment method within about two weeks. A few cost notes:
This is the single biggest gotcha and the one most articles miss: if you bought your Casper mattress from Costco, Amazon, Target, or any other reseller, the 100-night trial does not apply through Casper. You must return the mattress under that retailer's policy.
Costco, for example, has a famously generous return window but processes the refund themselves; Amazon's mattress return rules vary by seller. Always check the receipt and the retailer's policy before assuming Casper's terms cover the purchase.
Most major bed-in-a-box brands now offer a 100-night trial - Casper helped popularize it, but it's no longer a standout. The differences are in the fine print:
If a generous, no-questions trial matters most, Casper, Nectar, and Purple are roughly equivalent. If you want a longer window with low risk of being charged a return fee, Nectar's 365-night option is the most forgiving.
Casper's return policy holds up well in 2026 - but the version that lives in most people's heads (the original "100-night, no-questions" pitch from launch) leaves out the 30-night minimum, the per-product return cap, and the bundle and third-party caveats. If you're buying direct from casper.com and use a protector from night one, the trial is genuinely low risk. If you're buying through a reseller, treat the retailer's policy - not Casper's - as the binding contract.
Yes - the 100-night trial is designed for that. After a mandatory 30-night break-in period, you can return your mattress for a full refund any time before night 100, as long as it's free of stains, damage, and odors.
No. Returns are free in the contiguous U.S., with no restocking fee. In-home setup surcharges are non-refundable, but Hawaii and Alaska shipping costs are refunded with the return.
Refunds are credited to the original payment method within about two weeks after Casper picks up or receives the returned item.
Casper does not restock returned mattresses. They are donated to a local charity or recycled, which is why returns must be in donatable condition (no stains, rips, pet damage, or odors).
No. Mattresses purchased through third-party retailers follow that retailer's return policy, not Casper's. Always check your receipt and the reseller's terms before assuming the 100-night trial applies.
Only if unused and in original packaging, within 30 days of delivery. Once opened or slept on, soft goods are non-returnable for hygiene reasons but are covered by a one-year warranty against manufacturing defects.
