January 6, 2026 – A consumer has reported significant fiberglass contamination and extensive property damage following the removal of the zippered cover from their Casper CAS10A-P-MFR-ONT mattress. The incident, which occurred on December 6, 2025, has led to fiberglass being distributed throughout the consumer’s home, causing physical injury and an estimated tens of thousands of dollars in damages and cleanup costs.

Product Details

Brand Name: Casper

Incident Report Number: 20251213-3D2D6-2147325604

Incident Overview

The incident began on December 6, 2025, when the consumer decided to wash the zippered mattress cover of their Casper CAS10A-P-MFR-ONT mattress, purchased in 2017. The consumer noted that there was no “do not remove” sign on the cover; in fact, the product label included washing instructions, which prompted the action. Upon removal, the consumer initially observed “things coming out of it,” which they initially dismissed as dust.

As the cover was moved downstairs, more “stuff” began to emerge, covering the consumer. Subsequent research revealed that this substance was fiberglass. At this point, fiberglass had already spread extensively throughout the consumer’s residence, contaminating floors, carpets, walls, and clothing. The affected mattress cover was immediately taken outside, where further evidence of widespread fiberglass contamination was visible.

The consumer reported significant fear due to the known health hazards associated with fiberglass exposure. They contacted Casper Sleep, Inc., which reportedly offered a new mattress. However, the extent of the damage has prompted the consumer to seek legal advice, as an estimated $10,000 worth of belongings had to be discarded, including replacing carpets, which are impossible to clean of fiberglass. A HAZMAT company quoted $24,000 for proper cleaning, a cost the consumer stated they could not afford, leading them to undertake the arduous cleaning process themselves for over a week. Injuries reported include fiberglass embedded in the skin, with ongoing concerns about potential long-term lung damage for both the consumer and their son due to the exposure.

Safety Concerns

This incident highlights several critical safety concerns associated with mattresses that contain fiberglass as a fire retardant layer, especially when the outer cover is removable.

  • Immediate Dangers:

* Skin Irritation: Direct contact with fiberglass shards can cause severe skin irritation, itching, and embedded fibers, leading to discomfort and potential secondary infections. The consumer reported fiberglass embedded in their skin.
* Respiratory Issues: Inhalation of airborne fiberglass particles can irritate the respiratory tract, leading to coughing, sore throat, and breathing difficulties. While the consumer reported no immediate lung issues, the risk of developing short-term respiratory distress is significant.
* Eye Irritation: Fiberglass particles can irritate and damage the eyes upon contact.

  • Long-Term Risks:

* Chronic Respiratory Damage: Prolonged or significant exposure to inhaled fiberglass can potentially lead to chronic respiratory problems, including lung inflammation and, in severe cases, more serious lung conditions. The consumer expressed worry about long-term damage for themselves and their son.
* Allergic Reactions: Some individuals may develop allergic reactions or increased sensitivities to fiberglass over time.

  • Who Might Be Affected:

* Occupants of the Home: Anyone living in a home contaminated with fiberglass, especially young children who are closer to the floor and more likely to interact with contaminated surfaces, is at risk.
* Pets: Household pets can also be affected by contact with or inhalation of fiberglass particles.
* Cleaning Personnel: Anyone attempting to clean up fiberglass without proper personal protective equipment (PPE) is at risk of exposure.

  • Property Damage Potential:

* Extensive Contamination: Fiberglass, once airborne, can settle on virtually all surfaces, including furniture, clothing, HVAC systems, and porous materials like carpets and upholstery.
* Irreparable Damage: Many items, especially porous ones, may be impossible to clean effectively and safely, necessitating their disposal. The consumer reported discarding over $10,000 worth of items and replacing carpets.
* High Remediation Costs: Professional HAZMAT cleaning services are often required to safely and thoroughly remove fiberglass contamination, costing tens of thousands of dollars, as illustrated by the $24,000 quote received by the consumer.

What Consumers Should Do

If you own a Casper mattress or any mattress with a zippered cover purchased around 2017, and are concerned about fiberglass content, please follow these guidelines:

  • Do Not Remove the Mattress Cover: Unless the manufacturer explicitly states that the cover is designed for regular washing and removal, and provides clear instructions free of ambiguity regarding fiberglass, *do not remove* any zippered mattress cover. Many covers are part of a fire barrier system that contains fiberglass.
  • Inspect Product Labels: Carefully check your mattress labels for warnings about fiberglass or instructions regarding the outer cover.
  • Avoid Spreading Contamination: If you suspect fiberglass exposure or contamination, do not use fans, vacuums (especially household vacuums without HEPA filters), or brooms, as these can aerosolize and spread fiberglass particles further.
  • Isolate the Product: If you believe your mattress has released fiberglass, carefully cover it with plastic sheeting (e.g., painter’s plastic) and tape it securely. Move it to an isolated area or outdoors if possible, minimizing contact.
  • Seek Medical Attention: If you experience skin irritation, respiratory issues, or other symptoms after potential fiberglass exposure, consult a healthcare professional.
  • Professional Cleaning: If your home has been contaminated with fiberglass, it is highly recommended to consult with a professional HAZMAT or mold remediation company specializing in hazardous material cleanup. They have the necessary equipment and expertise to safely remove fiberglass.
  • Report the Incident: If you experience a similar incident, report it to the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov and directly to the mattress manufacturer.
