Almost every mattress you'll ever shop for is "on sale." That's not a coincidence, and increasingly, it's not legal in the way retailers are doing it. Several mattress companies are currently defending themselves in court — and one group already paid out over the exact same allegation: the discount you're being shown was never really a discount at all.
The mechanics are simple. A retailer sets a "regular" or "list" price on a product page — a number that's rarely, if ever, actually charged to a customer. Then a "sale" price appears next to it, struck through, framed as a limited-time discount. When that promotion is scheduled to expire, it doesn't really end — it gets replaced by a new one under a different seasonal name (a holiday, a "flash sale," an anniversary event) at the same or a similar markdown. The struck-through number never moves. Only the banner does.
The effect is a permanent discount dressed up as an urgent, temporary one — designed to make you feel like you need to act now, when the price you're looking at is simply the price.
These aren't hypothetical concerns. They are active and recently settled legal claims, with specific numbers attached.
Two separate lawsuits — Wong v. Mattress Firm Inc. (N.D. Cal., Case No. 3:26-cv-01364) and Milito v. Mattress Firm Inc. (King County, WA Superior Court, Case No. 2:26-cv-00227) — allege the retailer advertised mattresses at steep markdowns from "regular" prices that were "almost always" the actual selling price. One complaint cites strike-through prices of $799.99 and $1,399.99 marked down to $374 and $674 — discounts advertised as "up to 46% off." The suits allege the promotions rotated "sale themes, such as holiday or seasonal promotions, while continuing to offer the same or similar discounts without interruption."

The same reporting notes a separate suit accusing Puffy of "using fake sales and discounts to mislead consumers into purchasing its products." Fewer specifics have been reported publicly on this case than on the Mattress Firm suits, but the underlying allegation is the same pattern of inflated reference pricing.

Night US, LLC and Brooklyn Bedding LLC, which operate leesa.com, brooklynbedding.com, helixsleep.com, and bearmattress.com, agreed to an estimated $8.16 million in class benefits after being accused of displaying "crossed-out original prices and limited-time sales that did not reflect true regular retail prices" — described in the case as "phantom discounts" creating "a false sense of urgency." The settlement covers roughly 74,000 qualifying orders placed on those four sites between 2019 and 2024, with eligible buyers entitled to $110 cash or a $110 store-credit voucher.

You don't need a lawsuit to protect yourself — you need a few minutes and the right habits before you check out.
To be direct about what this page is and isn't: this is a buyer-education guide, not a promise that we run a live, historical price-tracking database. We don't have that infrastructure today, and we're not going to claim we do.
What we do, as an ongoing practice: when we review a specific mattress, we spot-check its listed "sale" price against what we saw during earlier checks of that same model. If a discount looks like it's been running unchanged for months under a rotating banner, we'll say so plainly in that review rather than repeating the advertised "% off" figure at face value.
"A 'sale' that never ends isn't a sale — it's a price with a costume on. We'd rather tell you that plainly than let a countdown timer do the talking for us."
