The Consumer Product Safety Commission issued three recall alerts last Thursday for mattresses sold on Amazon because they do not meet mandatory flammability standards, increasing fire risk.
The CPSC recalled 48,405 Kesyup-branded mattresses because of their flammability risk. The recalled mattresses are 12 inches thick and were sold in various sizes, including twin, full, queen and king. The mattresses pose a risk of serious injury or death from a fire, according to the recall, which states that no injuries have been reported.
The CPSC also published a recall for 792 WinxMatrs mattresses for violating mandatory flammability standards. The recalled mattresses were sold in black on Amazon.com from August 2025 through November 2025 for about $120. They came in a twin size and were 10 inches thick. No injuries were reported in relation to that recall either.
Another 263 mattresses, under the brand Emerspring, were also recalled, for similar reasons.
Research from Leggett & Platt shows that many low-cost imported mattresses sold online fail federal flammability standards. It also says some even attain dangerous heat release rates in violation of U.S. law in as little as two to four minutes after exposure to an ignition source, according to test results submitted to the U.S. Consumer Product Safety Commission in July 2024.
The lab tested eight imported mattress models (24 mattresses in total). These models had an average retail listing price of $233 — about half the wholesale price of an average mattress sold by U.S. manufacturers.
Seven of the eight tested mattress models (87.5%) failed the 1633 flammability test. One mattress model per brand was subjected to 1633 flammability testing. Five brands each had at least one model that failed all three 1633 tests conducted. Two of the brands had a model that failed two of three 1633 tests.
An estimated 400,000 mattresses from models that failed 1633 flammability testing were sold on Amazon between 2024 and mid-2025, according to third-party market intelligence data. Many mattress brands identified as having noncompliant models continue to sell those models — as well as other models—on Amazon and other online retailers in the U.S.
The CPSC adopted this safety standard to reduce deaths and injuries related to mattress fires, particularly those initially ignited by sources such as lighters, candles and matches. The standard requires mattresses to maintain a heat release rate under 200 kW after being ignited by a pair of T-shaped gas burners.
Noncompliant mattresses burn rapidly and can quickly reach dangerous “flashover” conditions. Flashover is the point at which the entire contents of a room ignite simultaneously by radiant heat, making conditions in the room untenable and safe exit from the room impossible.
Each year, compliance with the 1633 standard prevents scores of deaths and serious injuries from bedroom fires. To be compliant, a particular mattress design must pass the 1633 test three times. A single failure is considered to be a failure of the design to meet the 1633 standard.
Unfortunately it’s the same industry “leaders” like Leggett and the MRC that are killing our industry. The overseas manufacturers namely China can drown any industry with product regardless of what laws are in existence. They just make more product under a different name and ship it out to whoever wants a nice looking cheap mattress shipped to their home without having to lift a finger. The MRC is just lining their pockets while swindling mattress buyers, manufacturers and retailers. They created a whole industry out of nothing like they did with TB603 over 20 years ago here in California. The MRC is a “non profit” that does nothing but grease politicians into making their ridiculous idea into law at an exorbitant cost. There’s a reason why only a small handful of states comply, there is a whole market now of recycling centers that are now making mattresses or reselling the used mattresses they collect to mattress renovators or even to the general public cash. The Bureau of Home Furnishings in California and the MRC cannot agree on who’s in charge and the laws contradict each other. Leggett worries more about lobbying politicians than focusing on making an affordable product to compete with local manufacturers. They would rather leave an entire State than adapt to a changing industry.
