Incident Overview

On February 12, 2025, a consumer discovered that their Casper mattress, purchased in May 2016, was leaking fiberglass. While changing bedsheets, they felt a rash developing on their hand—similar to recurrent rashes experienced over the past year. Using a flashlight, they found shiny fibers on their clothing and extensive contamination throughout the bedroom, including bedding, curtains, carpet, and other surfaces. When the mattress was lifted, fiberglass fibers were visibly protruding from the cover and covering the bed slats.

The consumer reported that the mattress tags do not disclose the presence of fiberglass and instead encourage removing and washing the cover, which may release fibers. They experienced rashes on their arms, chest, legs, and face, and one of their cats developed respiratory issues after frequent exposure under the bed. A doctor later stated that fiberglass exposure was likely the cause of the rashes. The consumer closed off the room and contacted Casper, providing photo evidence.

Safety Concerns

Immediate Dangers: Fiberglass fibers can embed in skin, causing contact dermatitis and intense itching. Inhalation can irritate the respiratory tract, leading to coughing or difficulty breathing, especially in pets or individuals with pre-existing conditions.

Long-Term Risks: Chronic exposure to airborne fiberglass may cause persistent respiratory issues or skin sensitization. The microscopic fibers can remain airborne for extended periods, increasing the risk of repeated inhalation.

Who Might Be Affected: All household members and pets are at risk. In this case, a cat developed respiratory symptoms after playing under the contaminated bed. Children and animals are more vulnerable due to lower body weight and proximity to floor-level contamination.

Property Damage Potential: Fiberglass contamination can spread through HVAC systems, requiring professional remediation. In this incident, the consumer incurred over $10,000 in damages, including mattress removal and HVAC cleaning. Contaminated soft goods like curtains and carpets may need disposal.

What Our Clients Say

What Consumers Should Do

Stop Using Immediately: Cease using the mattress and isolate the affected area to prevent fiberglass from spreading to other parts of the home.
Do Not Attempt Cleanup: Do not vacuum or handle contaminated items without professional guidance, as this can aerosolize fibers. Avoid removing the mattress cover, as the manufacturer's instructions may release fiberglass.
Preserve the Product: Keep the mattress and all tags intact. Do not dispose of the product until a professional has assessed the situation, as it may be needed for evidence.
Document the Incident: Take photographs of the contamination, mattress tags, and any health effects. Keep records of communications with the manufacturer and receipts for remediation.
Seek Medical Attention: If you experience skin rashes, eye irritation, or respiratory symptoms, consult a healthcare provider and mention possible fiberglass exposure.
Report to the CPSC: File a report at SaferProducts.gov to help identify potential hazards and warn other consumers.

Manufacturer's Response

Casper Sleep offered to arrange pickup of the contaminated mattress and frame but asked the consumer to bag the mattress themselves. The consumer requested confirmation that the removal company, Sharetown, was certified to handle hazardous materials, but Casper could not provide this assurance. After the consumer provided a remediation quote from an IICRC-certified company, Casper did not respond for 21 days despite follow-ups.
