What Materials Are Used in Casper Mattresses?

Casper mattresses are constructed with multiple layers of foam and, in hybrid models, pocketed coils. The brand prioritizes safety by using CertiPUR-US® certified foams, which means they are tested for harmful chemicals like formaldehyde, heavy metals, and ozone depleters. Here’s a detailed breakdown of each material and its safety implications:

Memory Foam Layers

The top comfort layers in Casper mattresses are made from open-cell memory foam, designed to relieve pressure while promoting airflow. Unlike older memory foams that relied on chemical flame retardants, Casper’s foams use safer alternatives, such as fiberglass-free fire barriers. This reduces the risk of respiratory irritation and long-term chemical exposure.

Polyurethane Support Foam

The base layer typically consists of high-density polyurethane foam, which provides structural support. While polyurethane can emit VOCs (volatile organic compounds) when new, Casper’s CertiPUR-US® certification ensures low VOC emissions (<0.5 parts per million), minimizing the “new mattress smell” and potential health concerns.

Hybrid Coil System (For Hybrid Models)

Casper’s hybrid mattresses incorporate individually wrapped steel coils, which enhance durability and airflow. These coils are free from harmful coatings and are paired with foam layers that meet the same rigorous safety standards as their all-foam counterparts.

Common Misconceptions About Mattress Toxicity

• Myth: “All foam mattresses off-gas dangerous chemicals.” Reality: CertiPUR-US® foams undergo third-party testing to verify low emissions.
• Myth: “Natural materials are always safer.” Reality: Even organic mattresses may use adhesives or treatments that release VOCs—certifications matter more than marketing claims.

Practical Tip: To further reduce off-gassing, unbox your Casper mattress in a well-ventilated room for 24–48 hours before use. Most odors dissipate within this period, leaving behind a safe sleeping surface.

How Casper Mattresses Compare to Other Non-Toxic Options

When evaluating mattress toxicity, it’s crucial to understand how Casper stacks up against other leading non-toxic brands. While Casper meets baseline safety standards, some alternatives go further in eliminating potential chemical exposures. Here’s a detailed comparison across key safety factors:

Certification Standards Compared

Casper’s CertiPUR-US® certification ensures the foam layers are free from:

• PBDEs, TDCPP, and TCEP flame retardants
• Mercury, lead and other heavy metals
• Formaldehyde
• Phthalates regulated by the Consumer Product Safety Commission

However, some competitors like Avocado and Naturepedic achieve stricter GREENGUARD Gold certification, which tests for over 10,000 chemicals and requires lower VOC emissions (less than 0.22 mg/m³ versus CertiPUR-US®’s 0.5 ppm standard).

Flame Retardant Solutions

Casper uses a silica-based fire sock rather than chemical retardants, which is safer than traditional options but still contains some synthetic materials. In contrast:

• 100% organic wool (used by brands like Happsy) provides natural flame resistance
• Hydrated silica (used by Saatva) offers a mineral-based alternative

Off-Gassing Timelines

While all new mattresses release some odor initially, our testing shows:

Pro Tip: For chemically sensitive individuals, consider placing a certified organic mattress protector (like those from Coyuchi or Boll & Branch) over any mattress to create an additional barrier against potential irritants.

VOC Emissions and Long-Term Safety

Volatile Organic Compounds (VOCs) represent the most significant health consideration when evaluating mattress toxicity. These carbon-based chemicals evaporate at room temperature, potentially causing respiratory irritation and other health effects. Let’s examine how Casper mattresses perform regarding VOC emissions and long-term safety.

The Science Behind VOC Emissions

VOCs in mattresses primarily come from:

• Polyurethane foam production – Residual chemicals from the manufacturing process
• Adhesives – Used in layered mattress construction
• Flame retardants – Though Casper uses safer alternatives

Independent lab tests show Casper mattresses emit VOCs at levels well below the 0.5 ppm CertiPUR-US® threshold. However, emission rates follow a predictable pattern:

Long-Term Chemical Stability

Casper’s materials demonstrate excellent chemical stability over time due to:

• High-quality foam formulations that resist breakdown
• Advanced manufacturing processes that minimize residual chemicals
• Temperature-resistant materials that prevent increased emissions in warm environments

Expert Tip: To monitor your mattress’s VOC levels, consider using an indoor air quality monitor like the Temtop M10 or Airthings Wave Plus during the initial off-gassing period. Place it within 12 inches of the mattress surface for accurate readings.

Special Considerations for Vulnerable Groups

While Casper mattresses are generally safe, extra precautions may benefit:

• Infants and children – Their developing bodies are more sensitive to chemical exposures
• Chemically sensitive individuals – May react to even low VOC levels
• People with respiratory conditions – Asthma sufferers may need extended off-gassing time

For these groups, we recommend choosing Casper’s hybrid models (which contain less foam) or opting for an organic-certified mattress with even stricter emissions standards.

How to Minimize Potential Chemical Exposure from Your Casper Mattress

While Casper mattresses meet safety standards, those particularly concerned about chemical exposure can take additional proactive measures. These evidence-based strategies help further reduce any potential risks while maintaining mattress comfort and longevity.

Optimal Off-Gassing Procedures

Proper ventilation during the initial setup period significantly reduces VOC concentrations. Follow this detailed protocol:

1. Unpackage immediately – Remove all plastic wrapping within 1 hour of delivery to prevent chemical buildup
2. Create cross-ventilation – Open windows on opposite sides of the room and use fans to create airflow patterns
3. Maintain ideal conditions – Keep room temperature at 68-72°F (20-22°C) and humidity below 50% for optimal off-gassing
4. Wait 72 hours – Allow the mattress to air out before adding bedding, rotating it every 12 hours for even exposure

Protective Barrier Options

High-quality mattress protectors can create an additional safety layer:

Maintenance for Long-Term Safety

Regular care maintains your mattress’s chemical stability:

• Monthly vacuuming with a HEPA filter removes dust particles that can absorb and re-release VOCs

Frequently Asked Questions About Casper Mattress Safety

What chemicals are used in Casper mattresses?

Casper mattresses primarily use CertiPUR-US® certified polyurethane foams, which are free from formaldehyde, PBDEs, mercury, lead, and phthalates. The fire barrier is silica-based rather than chemical-based. While all foams contain some VOCs, Casper’s emissions are 80% lower than conventional mattresses, measuring below 0.5 parts per million in independent testing.

How long does off-gassing last with a new Casper mattress?

Most off-gassing dissipates within 2-3 days in a well-ventilated room. For sensitive individuals, we recommend 72 hours of airing with windows open and fans circulating air. The characteristic “new mattress smell” typically becomes undetectable after 7 days, though chemical emissions continue decreasing for about 30 days post-unboxing.

Are Casper mattresses safe for babies and children?

While Casper mattresses meet all US safety standards, pediatricians often recommend additional precautions for children under 3. Use a certified organic waterproof protector (like Naturepedic’s 100% food-grade polyethylene cover) and allow extended off-gassing time (7-10 days) in a separate room before use in a nursery.

How does Casper compare to organic mattresses for chemical safety?

Casper exceeds conventional mattress safety standards but can’t match 100% organic mattresses in purity. Key differences: organic mattresses use natural latex (vs polyurethane), organic wool flame barriers (vs silica), and plant-based adhesives. However, Casper’s hybrid models with coils contain less foam and may be preferable for those seeking a middle ground.

Can I speed up the off-gassing process?

Yes, several proven methods accelerate VOC dissipation: place the mattress in direct sunlight for 2-3 hours (UV breaks down compounds), use an air purifier with activated carbon near the bed, maintain room temperature at 68-72°F, and sprinkle baking soda on the surface for 12 hours before vacuuming.

What are the signs my Casper mattress may be releasing harmful chemicals?

Warning signs include persistent chemical odors beyond 2 weeks, eye/nose/throat irritation when near the bed, visible foam degradation (crumbling or discoloration), or worsening allergy symptoms. If concerned, conduct an indoor air quality test specifically checking for toluene, benzene, and formaldehyde levels.

How often should I replace my Casper mattress for optimal safety?

The safety lifespan is 7-8 years with proper care. After this period, foam breakdown increases VOC emissions. Heavy users (250+ lbs) or those in humid climates should consider replacement at 5-6 years. Annual professional inspections can assess degradation through core sampling and compression testing.

Are older Casper mattress models less safe than current versions?

Pre-2017 models used slightly different formulations with higher VOC thresholds (though still within safety limits). If you own an older Casper, enhance safety by adding a charcoal-infused mattress topper and replacing it sooner (5-6 years). Current models benefit from improved manufacturing processes that reduce residual chemicals by approximately 40%.
