Temperature Regulation & Breathability
Memory Foam
Temperature Rating:
Warm to Neutral (Cool with gel infusion)
Breathability:
Poor to Fair - Traditional closed-cell memory foam structure significantly restricts airflow causing heat retention. Body heat can increase surface temperature by 5-10 degrees. Modern improvements like gel infusion, copper infusion, open-cell structure, and ventilation channels improve breathability but memory foam still retains more heat than latex, down, or buckwheat.
Microbeads
Temperature Rating:
Cool to Neutral
Breathability:
Excellent breathability due to air spaces between millions of individual beads. Air circulates freely through bead structure preventing heat buildup and moisture retention. Significantly more breathable than solid foam materials like memory foam. However, breathability can vary based on fabric casing - tight-weave fabrics restrict airflow while mesh or stretchy fabrics enhance circulation. The 98% air composition of expanded polystyrene beads promotes natural temperature regulation. Sleeps cooler than most synthetic pillows.

Allergen Resistance & Health Concerns
Memory Foam
Hypoallergenic:
Allergies:
Dense cellular structure naturally resists dust mites, mold, and mildew making it hypoallergenic for most people. However, some individuals may experience reactions to chemicals used in manufacturing such as isocyanates, polyols, or flame retardants. Those with chemical sensitivities should look for CertiPUR-US or OEKO-TEX certifications.
Dust Mites:
Excellent resistance to dust mites due to dense cellular structure that prevents mite penetration and colonization. Studies show dust mite populations in memory foam bedding are 70-85% lower than traditional materials. Memory foam is one of the best options for dust mite allergy sufferers, comparable to latex.
Chemical Concerns:
Lower-quality memory foam may contain volatile organic compounds (VOCs), formaldehyde, flame retardants (PBDEs), and other potentially harmful chemicals. Off-gassing smell indicates VOC release. Look for CertiPUR-US certification ensuring foam is made without ozone depleters, PBDEs, TDCPP flame retardants, mercury, lead, heavy metals, formaldehyde, and phthalates. OEKO-TEX Standard 100 and Greenguard Gold certifications provide additional assurance of low emissions.
Microbeads
Hypoallergenic:
Allergies:
Generally hypoallergenic for most users. Synthetic polystyrene beads do not contain proteins that trigger allergic reactions. Material naturally resists dust mite colonization, mold growth, and mildew. However, individuals with chemical sensitivities may react to residual styrene vapors, though levels are extremely low in finished products (estimated exposure around 6.6 micrograms per person per day, well below FDA safety limits). Outer fabric casing may harbor allergens over time if not cleaned regularly. Overall considered safe for allergy sufferers when compared to natural fill materials.
Dust Mites:
Synthetic polystyrene material provides inhospitable environment for dust mites. Beads do not provide food source for dust mites (which feed on dead skin cells and natural fibers). However, dust mites can colonize on outer fabric casing over time. The bead core itself remains largely protected from dust mite infiltration when casing is intact. Regular cleaning of outer casing or use of removable, washable covers significantly reduces dust mite accumulation. Research shows synthetic materials accumulate fewer dust mites than natural materials when properly maintained.
Chemical Concerns:
Polystyrene beads are manufactured from styrene monomer, a chemical classified by the International Agency for Research on Cancer (IARC) as Group 2A "reasonably anticipated to be a human carcinogen" based on occupational exposure studies. However, the U.S. National Toxicology Program states that styrene levels from polystyrene consumer products are "hundreds if not thousands of times lower" than occupational exposures. FDA has determined polystyrene safe for consumer use with estimated daily styrene exposure at 6.6 micrograms per person per day - over 10,000 times below FDA safety limits. New pillows may off-gas slight chemical odor initially that dissipates within days. Choose OEKO-TEX Standard 100 certified products ensuring no harmful substances.
Care & Maintenance
Memory Foam
Washable:
Washing Instructions:
Solid memory foam cannot be washed - spot clean only with mild detergent and cool water. Shredded memory foam covers may be washable if manufacturer specifies - always check care label. Never submerge solid memory foam.
Drying Instructions:
Air dry completely in well-ventilated area away from direct heat and sunlight. Never put memory foam in clothes dryer as heat permanently damages the cellular structure. Allow 24-48 hours for complete drying.
Maintenance Tips:
- •Use a removable, washable pillow protector made from breathable fabric to keep foam clean and extend lifespan
- •Air out the pillow weekly by removing cover and placing in well-ventilated area for 3-4 hours minimum
- •Rotate pillow 180 degrees every 1-2 weeks to prevent permanent body impressions and distribute wear
Microbeads
Washable:
Washing Instructions:
NOT machine washable. Machine washing will tear thin fabric casing releasing millions of beads that clog washing machines and plumbing. Some manufacturers provide removable outer covers that can be washed separately while inner bead bladder remains unwashed. Never submerge microbead core in water.
Drying Instructions:
Not applicable - inner bead core should never be washed. If outer cover is removable, tumble dry cover on low heat or air dry flat. Keep microbead core away from all heat sources including dryers as heat can melt or damage polystyrene beads.
Maintenance Tips:
- •Spot clean outer fabric only with damp cloth and mild soap - never saturate
- •Use removable pillowcase over microbead pillow to keep exterior clean
- •Shake and fluff daily to redistribute beads and maintain even distribution

- •Foam density - Higher density (4-5 lbs/ft³) lasts significantly longer than low-density (2-3 lbs/ft³) foam
- •Frequency of use and sleeper body weight affecting compression rate and foam fatigue
- •Quality of pillow cover protecting foam from moisture, body oils, and environmental contaminants
- •Room temperature and humidity levels affecting foam molecular structure and breakdown rate
- •Proper care including regular rotation to distribute wear evenly across the foam
- •Manufacturing quality and adherence to standards like CertiPUR-US indicating better longevity
Microbeads
Factors Affecting Lifespan:
- •Fabric casing quality - higher quality casings prevent tearing and bead loss
- •Frequency of use and pressure applied - heavy use compresses beads faster
- •Storage conditions - must be kept away from heat sources that can melt polystyrene
- •Exposure to sunlight - UV radiation degrades polystyrene causing brittleness
- •Quality of bead manufacturing - well-made beads resist compression longer
- •Handling care - rough treatment increases risk of casing tears
Environmental Impact & Sustainability
Memory Foam
Sustainability:
Memory foam is petroleum-based polyurethane and is not biodegradable. Manufacturing is energy-intensive producing significant greenhouse gas emissions. Foam does not decompose in landfills and can persist for hundreds of years. Some manufacturers now offer plant-based or bio-foam memory foam using soybean oil or other renewable materials (up to 30% bio-content), offering marginally better sustainability but still predominantly petroleum-derived.
Biodegradable:
Manufacturing:
Petroleum-based polyurethane production has substantial environmental impact including fossil fuel extraction, processing, and chemical synthesis. Manufacturing process releases VOCs and greenhouse gases. Energy-intensive production requires high temperatures and pressures. Newer plant-based foams reduce but don't eliminate petroleum dependence. Proper certifications ensure manufacturing follows environmental and worker safety standards.
Microbeads
Sustainability:
Extremely poor environmental profile - one of the worst pillow materials for sustainability. Polystyrene is petroleum-based, non-renewable, and non-biodegradable. Research confirms expanded polystyrene (EPS) persists in landfills for approximately 500 years with minimal degradation when shielded from sunlight. Manufacturing process is energy-intensive, contributing to greenhouse gas emissions and consuming fossil fuel resources. Styrene production releases millions of pounds of toxic air pollutants including styrene, benzene, and ethylbenzene into atmosphere annually. Lightweight beads easily escape into environment causing significant marine pollution - polystyrene constitutes major component of ocean plastic waste. Breaks down into harmful microplastics that enter food chain and ecosystems. Almost no recycling infrastructure exists for microbead pillows.
Biodegradable:
Manufacturing:
High environmental impact manufacturing process. Polystyrene production begins with extraction of petroleum and chemical synthesis of styrene from benzene and ethylbenzene - both toxic carcinogenic compounds. Expansion process uses pentane gas and steam at high temperatures consuming significant energy. U.S. styrene facilities report releasing approximately 32 million pounds of styrene, 3.2 million pounds of benzene, and 2.1 million pounds of ethylbenzene into air annually according to EPA Toxics Release Inventory data. Manufacturing contributes to global warming, air pollution, and disproportionately impacts frontline communities near production facilities. Recycling rate for EPS remains extremely low due to collection and processing challenges. When incinerated for disposal, releases toxic substances including styrene gas and polycyclic aromatic hydrocarbons (PAHs) into atmosphere.
