Temperature Regulation & Breathability
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.
Straw
Temperature Rating:
Cool
Breathability:
Excellent breathability and temperature regulation due to hollow tubular structure of wheat stalks allowing superior air circulation. The natural spacing between straw pieces creates air channels that prevent heat buildup. Straw remains cool to the touch and does not retain body heat like dense foam materials. This cooling property made straw popular in hot climates historically. However, the same porous structure that provides breathability also allows dust mite colonization and particle accumulation.

Allergen Resistance & Health Concerns
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.
Straw
Hypoallergenic:
Allergies:
Straw is NOT hypoallergenic despite being gluten-free (gluten is in wheat grain, not stalks). While straw itself rarely causes direct allergic reactions, it readily harbors dust mites, mold, and accumulates environmental allergens. The organic material provides food and habitat for dust mites, which are among the top five most common allergens. As straw breaks down over time, it creates fine dust particles that can irritate airways and trigger respiratory symptoms. Studies on natural organic bedding materials show they accumulate allergens more rapidly than synthetic alternatives. Anyone with dust mite allergies, asthma, or respiratory sensitivities should avoid straw pillows.
Dust Mites:
Straw provides an ideal environment for dust mite colonization and allergen accumulation. The organic material serves as food source for mites, while the structure creates warm, protected spaces for mite habitation. Research shows natural organic materials accumulate dust mite allergens more rapidly than synthetic alternatives. As straw breaks down into fine particles, it creates additional dust that can harbor mite feces and body parts - the actual allergen sources. Cannot be washed to remove mite allergens. For dust mite allergy sufferers, straw pillows are among the worst options and should be avoided entirely.
Chemical Concerns:
Minimal chemical concerns when using organic wheat straw - naturally grown agricultural byproduct without synthetic processing. Conventionally farmed wheat straw may contain pesticide residues from crop treatment. Look for USDA Organic certified wheat straw to ensure no pesticide, herbicide, or synthetic fertilizer exposure. No VOC off-gassing or synthetic additives. However, some processors may treat straw with anti-pest chemicals - verify processing methods. The natural lignin and cellulose in straw are non-toxic plant compounds.
Care & Maintenance
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
Straw
Washable:
Washing Instructions:
NOT WASHABLE. Straw cannot be washed as water exposure causes immediate decomposition, breakdown, and potential mold growth. Once soiled, the entire pillow must be discarded and replaced. This is a major hygiene limitation of straw pillows.
Drying Instructions:
Cannot be dried after washing. If straw becomes damp from humidity or sweat, air out pillow outdoors in direct sunlight for several hours. Ensure complete dryness before returning to use to prevent mold formation.
Maintenance Tips:
- •Air out weekly outdoors in direct sunlight for 2-3 hours to prevent moisture buildup and kill potential mites
- •Shake and fluff daily to redistribute straw pieces and prevent permanent compression in one area
- •Use multiple pillow protectors - thick inner cover prevents stalk penetration plus washable outer pillowcase

Durability & Longevity Factors
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
Straw
Factors Affecting Lifespan:
- •Quality of initial processing - properly cleaned and debris-free straw lasts longer
- •Humidity and moisture exposure - damp conditions accelerate decomposition and mold growth
- •Frequency of use and head weight - heavier use causes faster compression and breakdown
- •Quality of pillow cover - thick, tightly woven covers prevent stalks from protruding
- •Storage conditions - must be kept completely dry in well-ventilated area
- •Pest exposure - insects and rodents attracted to organic material can damage fill
- •Initial dryness of straw - properly dried straw at harvest time lasts longer than damp straw
Environmental Impact & Sustainability
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.
Straw
Sustainability:
Exceptionally sustainable and environmentally friendly material. Wheat straw is an agricultural byproduct that would otherwise be discarded or burned after grain harvest, making pillow use a form of upcycling waste. No additional farming, land use, or resources required beyond existing wheat production. Utilizing straw prevents open-field burning which releases significant CO2 and air pollution. Wheat plants absorb atmospheric CO2 during growth, making straw carbon-negative when sequestered in products. Requires virtually zero processing energy - simple cleaning and drying. Provides additional income stream for farmers from waste material, supporting rural agricultural economies. Completely renewable with annual wheat harvests.
Biodegradable:
Manufacturing:
Minimal manufacturing impact - among the lowest embodied energy of any pillow material. Process involves: collection after wheat harvest, drying if needed, removal of seeds and debris, and simple filling into pillow covers. No chemical processing, energy-intensive manufacturing, water usage, or industrial facilities required. Can be processed at farm level or through simple local facilities. Transportation is the primary energy input. At end of life, straw decomposes naturally within 90-180 days in compost, enriching soil with organic matter and nutrients. Creates zero waste in circular agricultural system. However, very short lifespan means frequent replacement, which may offset some environmental benefits compared to longer-lasting natural alternatives like latex or wool.
