Temperature Regulation & Breathability
Lyocell
Temperature Rating:
Excellent cooling - superior moisture management
Breathability:
Exceptional breathability due to unique fiber structure and moisture management capabilities. The nanofibril channels within each lyocell fiber create microscopic pathways allowing continuous air circulation while simultaneously absorbing and releasing moisture vapor. Scientific studies confirm lyocell absorbs moisture 50% more efficiently than cotton while wicking it away from skin surface and dispersing into surrounding air. This superior moisture management prevents the buildup of heat and humidity against skin that occurs with cotton and synthetic fabrics. The smooth fiber surface further enhances air permeability compared to cotton's rougher, moisture-holding structure. Independent testing consistently ranks lyocell among the most breathable fabrics available, ideal for hot sleepers and humid climates. The fabric actively supports body's natural thermoregulation by maintaining dry microclimate against skin surface.
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
Lyocell
Hypoallergenic:
Allergies:
Lyocell is naturally hypoallergenic and excellent for allergy sufferers. The smooth, non-irritating fiber surface combined with superior moisture management creates inhospitable environment for dust mites and allergens. Clinical studies demonstrate that individuals with atopic dermatitis experience significantly reduced redness and itching when wearing lyocell clothing compared to conventional fabrics. The closed-loop production process avoids harsh chemicals, pesticides, and toxic substances found in conventional cotton processing, reducing chemical sensitivity reactions. When certified OEKO-TEX Standard 100, lyocell contains no harmful substances that could trigger allergic responses. The moisture-wicking properties keep fabric surface dry, preventing the damp conditions where dust mites and mold thrive. However, standard weave lyocell does not provide complete dust mite barrier unless combined with proper allergen-proof pillow protectors underneath.
Dust Mites:
Lyocell provides excellent protection against dust mites through multiple mechanisms. Superior moisture-wicking capability rapidly removes humidity that dust mites require for survival and reproduction—mites cannot thrive in dry environments below 50% relative humidity. The smooth fiber surface with reduced friction accumulates fewer dead skin cells (dust mite food source) compared to rougher cotton textures. Natural antibacterial properties from moisture management create less hospitable conditions for mites and other microorganisms. Studies show moisture control is more effective for dust mite prevention than chemical treatments. However, standard lyocell weave does not provide complete physical barrier against dust mites penetrating through fabric. For maximum protection, use lyocell pillowcases over allergen-proof pillow protectors with pore sizes under 10 microns. Regular washing in warm water (40°C) effectively removes any dust mites and allergens from lyocell fabric.
Chemical Concerns:
Lyocell production is remarkably free of toxic chemicals compared to conventional textile manufacturing. The revolutionary closed-loop process uses N-Methylmorpholine N-oxide (NMMO), a non-toxic organic solvent that is 99.8% recovered and reused—unlike viscose rayon which uses toxic carbon disulfide harmful to workers and environment. The eucalyptus and other wood sources grow naturally without pesticides, herbicides, fertilizers, or irrigation on sustainably managed FSC/PEFC certified plantations. No chemical bleaching required since lyocell emerges naturally white from production process. OEKO-TEX Standard 100 certification ensures finished fabric contains no harmful substances including formaldehyde, heavy metals, pesticides, or carcinogenic dyes. EU Ecolabel certification confirms environmentally responsible production throughout entire lifecycle. No VOC off-gassing or synthetic chemical residues. Ideal for chemical sensitivities and health-conscious consumers.
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
Lyocell
Washable:
Washing Instructions:
Machine washable in cold to lukewarm water (maximum 30-40°C) using gentle or delicate cycle. Use mild, eco-friendly liquid detergent—preferably eucalyptus-based or wool wash. Fully dilute detergent in water before adding pillowcases to prevent staining. Avoid detergents with Optical Brightening Agents (OBAs) which can weaken and discolor fibers. Wash similar colors together and turn pillowcases inside out to protect outer surface. Maximum spinning speed of 400 RPM to prevent fiber stress. Hand washing ideal for longest lifespan. Wash every 1-2 weeks or as needed.
Drying Instructions:
Air drying strongly recommended for maximum fabric longevity—hang or lay flat in well-ventilated area away from direct sunlight. If air drying, pillowcases may feel slightly stiff; remedy by tumbling in dryer on low heat for 10-12 minutes before hanging to achieve soft finish. If machine drying necessary, use lowest heat setting and remove while still slightly damp to minimize wrinkles. Never use high heat which causes shrinkage and fiber damage. Never wring out—gently press to remove excess water. Ensure completely dry before storage to prevent mildew.
Maintenance Tips:
- •Pre-wash new lyocell pillowcases before first use to remove any manufacturing residues and allow initial 3% shrinkage
- •Wash every 1-2 weeks—lyocell's antibacterial properties mean less frequent washing needed than cotton
- •Never use fabric softeners—coat fibers blocking natural moisture-wicking and breathability capabilities
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

Environmental Impact & Sustainability
Lyocell
Sustainability:
Lyocell represents one of the most sustainable textile production processes available. The revolutionary closed-loop manufacturing system recovers and reuses 99.8% of the organic solvent (NMMO) and 95% of process water, creating near-zero waste compared to conventional textile production. Lyocell uses 50% less carbon emissions and 50% less water than generic lyocell/modal, and approximately 20 times less water than cotton cultivation. The fiber is derived from FSC-certified or PEFC-certified sustainably managed forest plantations where eucalyptus, birch, beech, and spruce trees grow rapidly without irrigation (only natural rainfall), pesticides, or fertilizers on land unsuitable for food crops. These plantations do not compete with food production and support biodiversity. Eucalyptus trees specifically are highly efficient, yielding four times more fiber per acre than cotton while absorbing significant atmospheric CO2. Lenzing AG has received Platinum status from EcoVadis for three consecutive years for sustainability efforts. The production process is energy-efficient with some facilities recovering energy from bark and byproducts. REFIBRA™ technology further enhances sustainability by incorporating 30% recycled cotton scraps with wood pulp, diverting textile waste from landfills. EU Ecolabel certification confirms minimal environmental impact throughout entire product lifecycle.
Biodegradable:
Manufacturing:
Innovative closed-loop manufacturing process with minimal environmental impact. Wood chips from sustainably harvested trees are dissolved in non-toxic organic solvent (NMMO) in carefully controlled process. The cellulose solution is extruded through fine spinnerets creating smooth round fibers in "dry jet-wet spinning" process. The revolutionary aspect: 99.8% of the solvent and 95% of process water are continuously recovered, filtered, and reused in perpetual cycle, with only 0.2% requiring replacement. No toxic chemicals like carbon disulfide (used in viscose) involved. No chemical bleaching needed since fiber emerges naturally white. Production facilities often use renewable energy sources and recover energy from biomass byproducts. The entire process from wood pulp to finished fiber takes approximately two hours. Manufacturing facilities must meet stringent environmental standards including EU Ecolabel criteria covering resource efficiency, emissions, and chemical management. Look for TENCEL™ brand from Lenzing AG for guaranteed certified sustainable production, or Birla Excel which recovers 90%+ of chemicals. Generic lyocell may have lower environmental standards.
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.
