From the 2016 Sleepopolis review-site lawsuit to the 2020 IPO securities class action and ongoing fiberglass exposure claims, here is what shoppers should know about Casper's legal history before they buy.
Casper helped invent the bed-in-a-box category in 2014, and almost as soon as it became the category leader it began racking up lawsuits. The most famous one is the 2016 case against mattress review sites, but it is far from the only one. Below is a plain-English timeline of every major Casper-related lawsuit from 2016 through 2025, what each one was about, and what it means for someone shopping for a mattress today.
In April 2016 Casper filed suit against three popular mattress review sites: Sleepopolis (run by Derek Hales), Mattress Nerd, and Sleep Sherpa. Casper alleged that the sites were promoting reviews as independent while taking undisclosed affiliate payments from competing brands. Reporting from Fast Company (Oct 2017) and Vox (Sep 2017) lays out the timeline in detail.
Hales had originally given Casper a glowing review, then revised it 18 months later toward Leesa, a Casper competitor. Casper sued shortly after he declined to renew an affiliate deal. The case ended in a 2017 settlement: Casper provided financing that helped JAKK Media acquire Sleepopolis, Hales departed, and the site's recommendation modules were rewritten to point at Casper rather than at competitors.
Why it still matters: most online mattress reviews are affiliate-funded. The FTC requires disclosure, but the wording is often buried. Read the disclosure on every review site you use - including this one.
Filed in 2017, Paul Good v. Casper Sleep Inc. alleged that Casper used a third-party script from data broker NaviStone to capture visitors' keystrokes, mouse movements, and form input on casper.com - including data entered before a purchase was completed. The complaint framed the practice as unauthorized wiretapping under California's Invasion of Privacy Act.
The wiretapping case did not produce a precedent-setting ruling, but it kicked off a wave of similar suits against e-commerce sites running session-replay scripts. Casper, like most large retailers, has since updated its privacy notices and cookie banners.
Casper went public on February 6, 2020. The IPO priced below its target range and the stock fell sharply. By April 2020, Robert Lematta and other investors filed a securities class action - 20-CV-... in the Eastern District of New York - alleging that Casper's S-1 and IPO road show contained materially false or misleading statements about the company's growth, gross margins, and inventory.
After Casper was taken private by Durational Capital in early 2022, settlement negotiations continued. Per court notices on Strategic Claims Services, exclusion and claim deadlines for the Lematta settlement fell on November 8 and November 30, 2024, with a final approval hearing in early 2025. Eligible class members are former public shareholders, not consumers.
Most fiberglass class actions in the mattress industry have been filed against Zinus, Ashley, and other budget brands. Casper has not been the named defendant in a major class action over fiberglass at the time of writing, but it has been pulled into the conversation in two ways:
Casper's current product pages disclose that some models use a glass-fiber knit fire barrier. The label warning is consistent across the industry: do not unzip the cover and do not machine wash it. If the cover is removed, the inner sock can shed microscopic glass fibers throughout a home, and remediation often costs more than the mattress. For a model-by-model breakdown of which Casper SKUs contain fiberglass, see our guide on whether the Casper mattress has fiberglass.
The Lematta v. Casper Sleep Inc. securities class action had its claim filing deadline on November 8, 2024 and an objection deadline of November 30, 2024. That case was for investors who acquired Casper securities in or traceable to the February 2020 IPO. No active consumer class action over Casper mattresses has been certified as of mid-2026.
Some Casper models use a glass-fiber knit as the inner fire barrier. The cover label tells owners not to unzip the cover; doing so risks releasing microscopic glass fibers. Casper has not confirmed the exact year-by-year status of fiberglass in every SKU, so check the law label on the model you own.
Casper sued three review sites - Sleepopolis, Mattress Nerd, and Sleep Sherpa - alleging false advertising and unfair competition because the sites were taking affiliate payments from Casper competitors without clearly disclosing them. The case settled in 2017.
Not directly. According to Fast Company and Vox reporting, Casper provided financing that allowed JAKK Media to acquire Sleepopolis. Derek Hales, the original reviewer, left the site shortly after.
The lawsuits are about corporate behavior and marketing, not a recall on the mattresses themselves. The bigger practical risk for owners is the fiberglass fire barrier in some SKUs - so if you buy a Casper, never unzip and wash the cover. If that risk concerns you, look at brands that use a non-fiberglass fire barrier such as Saatva, Amerisleep, Avocado, or Bear.
