A 100-Night Trial and a 365-Day Window: What Casper and Brooklinen Actually Let You Return

Nobody buys a mattress instead of sheets. Here's how the two companies' return policies actually behave, night by night and dollar by dollar.

Read Vault was assigned to compare the Casper Original mattress against Brooklinen’s Luxe sheets as rival options, as though a shopper buys one instead of the other. They’re not substitutes — most people buying a mattress also need sheets. What the two products actually share is a policy worth examining side by side: a home-trial return and a straightforward return window, structured in almost opposite ways. One makes you wait before you’re allowed to act; the other charges a small fee every time you do.

Casper’s 100 Nights Include 30 You Aren’t Allowed to Use

Casper markets a 100-night trial on the Original mattress, but the company’s own trial terms build in a mandatory 30-night break-in period during which a return cannot even be requested. That leaves roughly 70 nights of the advertised 100 as the real evaluation window — a third of the trial exists on paper only.

A 100-night figure is what most competitors in the category also advertise, so it reads as standard. The mandatory first-30-nights rule is what actually separates a trial that starts the moment of delivery from one that only starts once a body has had a chance to adjust. Casper frames the waiting period as adjustment time; it is also 30 nights during which a buyer cannot act, no matter how obvious a problem already is by night three. A buyer who unboxes the mattress and immediately dislikes the firmness still has to wait out the full break-in regardless; a buyer who unboxes a set of sheets and immediately dislikes the feel can start a return that same day.

The Original queen costs $1,295 (twin $895 to king $1,695), and Casper excludes the Original from all sitewide sales, per the company’s own pricing page — so the trial period, not a future discount, is the main leverage a buyer has to judge the mattress before committing to it long-term.

• Free courier pickup once a return is approved
• No restocking fee
• Refund issued in 3 to 5 business days
• Returned mattresses are donated where possible, recycled otherwise

What CertiPUR-US Covers, and What It Doesn’t

The Original’s three foam layers are each CertiPUR-US certified, meaning they’ve been tested for content, emissions and durability by an independent, third-party program — a genuine certification, distinct from Casper’s own service commitments like the trial and the warranty. It says nothing about comfort, motion transfer or heat retention, the categories that actually determine whether a specific sleeper is satisfied with the mattress inside the trial window. A certified foam layer and a mattress a given body finds comfortable are two separate claims, answered by two separate kinds of evidence.

Brooklinen doesn’t carry an equivalent manufacturing-process certification for its sheets. Its OEKO-TEX Standard 100 mark applies the same third-party logic to a different question — substances in the finished fabric rather than foam content and emissions — so the two products each have one real, independently verified claim, just not a claim that answers the same question or that a buyer could line up side by side.

Brooklinen’s 365 Days Cost $9.95 Whenever You Use Them

Brooklinen’s return window runs a full year — 365 days — with no mandatory waiting period before a return can start. The tradeoff is a flat $9.95 return-shipping fee deducted from the refund, regardless of when in that year the sheets go back. On a $179 queen set, that’s roughly 5.5 percent of the purchase price — a small but real cost every single time the window gets used.

Compare that against Casper’s zero-cost return process and the difference in incentive structure becomes clearer. Casper can afford a fully free return in part because a mattress return is a bigger logistical event that the company has built specific infrastructure — free courier pickup — around, and because relatively few buyers act within the usable window. Brooklinen’s sheets are inexpensive enough, and simple enough to ship back in a standard mailer, that a flat small fee covers the company’s own return-shipping cost without needing a courier at all.

Two Different Shapes of Safety Net

The two structures suit different kinds of doubt. Casper’s makes a buyer wait to find out whether a mattress works for their body, then returns it free once they know. Brooklinen’s lets a buyer decide at any point over the next year, but never for free. Someone fairly confident about the sheets and mainly wanting a long safety net gets more out of Brooklinen’s structure; someone who genuinely doesn’t know whether a mattress will suit them is better served by Casper’s model, mandatory break-in and all — the wait exists precisely because a body needs time to register whether a mattress is wrong for it, in a way a bedsheet rarely requires.

The Warranties Pick Up Where the Trials Leave Off

After the return window closes, Casper backs the Original with a 10-year warranty covering indentation over 1 inch, foam splitting, and cover defects, while explicitly excluding normal softening — a meaningful carve-out, since softening over years of use is one of the more common ways a foam mattress actually changes.

Brooklinen’s warranty is different in kind, not just length: it’s a company-stated “lifetime warranty” against ripping, tearing and pilling — the company’s own wording, not a third-party-verified standard the way CertiPUR-US is for Casper’s foam. Owner reviews describing rips and pilling within months, and quality decline after about a year, are exactly the defects that wording claims to cover — which makes the 365-day return window, not the lifetime warranty, the mechanism that actually resolves most complaints that surface within the first year. Both companies’ promises are worth reading in full before assuming “warranty” means the same thing on a $1,295 mattress and a $179 sheet set.

Put the two purchases on the same timeline and the shape becomes clear: a Casper buyer’s real decision window closes at night 100, after which a 10-year warranty with real exclusions takes over; a Brooklinen buyer’s decision window stays open for a full year at a small recurring fee, after which a warranty resting on the company’s own wording is what’s left. Neither is wrong, but they are not the same kind of promise, and a shopper assuming otherwise is the one most likely to be surprised.
