Temperature Regulation & Breathability
Gel
Temperature Rating:
Cool
Breathability:
Limited breathability due to dense gel and foam construction. Gel layers are non-porous and don't allow air circulation. However, gel's superior thermal conductivity compensates by actively drawing heat away from head and neck. Better temperature regulation than standard memory foam despite similar breathability limitations. Some models incorporate ventilation channels or perforations to improve airflow. Overall performs well for hot sleepers through heat conduction rather than airflow.
Horsehair
Temperature Rating:
Cool
Breathability:
Exceptional breathability - among the best of all pillow materials. Each horsehair strand functions as a hollow tube with microscopic capillary action that channels away moisture while constantly funneling fresh air through the material. The natural curl of processed horsehair creates spacing between fibers allowing unobstructed air circulation. Horsehair is so effective at moisture management that if soaked with water and shaken, it dries almost immediately. This superior ventilation keeps the pillow cool and dry throughout the night, preventing the growth of fungi, bacteria, and dust mites that thrive in damp conditions. Temperature regulation is excellent - cool in summer, dry in winter.

Allergen Resistance & Health Concerns
Gel
Hypoallergenic:
Allergies:
Generally hypoallergenic with sealed gel and dense foam resisting dust mites, mold, and mildew. Gel materials are inert and rarely cause allergic reactions. However, some individuals may be sensitive to chemicals used in gel formulation including plasticizers, mineral oil, or styrene compounds. Foam components may trigger sensitivities in those reactive to polyurethane or petroleum-based materials. Look for CertiPUR-US and OEKO-TEX certifications ensuring reduced allergen concerns.
Dust Mites:
Excellent dust mite resistance. Dense foam and sealed gel layers create inhospitable environment for dust mite colonization. Mites cannot penetrate into foam structure or gel chambers. Smooth surfaces offer no habitat or food sources. However, pillow covers and protectors can harbor dust mites if not washed regularly. With proper cover maintenance, gel pillows provide superior dust mite protection compared to fiberfill or down alternatives.
Chemical Concerns:
Gel pillows contain synthetic materials with potential chemical concerns. Thermoplastic gels typically made from mineral oil (petroleum derivative), styrene-based polymers, and plasticizers. Some gel formulations contain phthalates or other additives of concern. Memory foam base may emit VOCs including formaldehyde, benzene, and other compounds. New gel pillows often have strong chemical odor requiring 3-7 days aeration. CertiPUR-US certification ensures foam meets standards for low VOC emissions and prohibited chemicals. Higher quality gel uses medical-grade materials with fewer concerning additives.
Horsehair
Hypoallergenic:
Allergies:
Properly processed horsehair is considered hypoallergenic and suitable for most allergy sufferers. The manufacturing process involves washing in boiling water, then steaming at 284°F (140°C) at four times atmospheric pressure with high humidity. This thorough sanitization removes proteins, allergens, and bacteria that could trigger allergic reactions. Multiple manufacturers report they have not encountered customers experiencing allergies to properly processed horsehair. The material has earned NOMITE certification, indicating suitability for house dust mite allergy sufferers. However, individuals with specific horse protein allergies should test before purchasing. Always verify the horsehair has undergone proper high-temperature processing rather than simple washing.
Dust Mites:
Horsehair provides excellent resistance to dust mite colonization when properly processed. The high-temperature steaming process (284°F at four times atmospheric pressure) kills any existing mites and removes allergens. More importantly, horsehair's superior moisture-wicking properties create an inhospitable environment for dust mites, which require warm, humid conditions and human skin scales for survival. The constant air circulation and rapid moisture removal prevent the damp conditions dust mites need to thrive. Many horsehair products earn NOMITE certification, the anti-allergen standard indicating suitability for house dust mite allergy sufferers. This makes horsehair significantly better for dust mite allergies than organic materials like down, wool, or cotton which retain moisture and provide favorable habitats.
Chemical Concerns:
Minimal chemical concerns when purchasing from reputable manufacturers. Quality horsehair processing involves only water, steam, and high heat - no bleaching or chemical treatments. The entire sanitization process at high temperatures and pressure is completed without addition of foreign substances or synthetic chemicals. Look for OEKO-TEX Standard 100 certification ensuring horsehair has been tested and verified free from harmful chemicals and substances. No VOC off-gassing or synthetic processing. However, be cautious of very cheap horsehair products which may undergo inferior processing or use chemical treatments. Always verify the manufacturer uses proper steaming methods at 284°F+ temperatures.
Care & Maintenance
Gel
Washable:
Washing Instructions:
Do NOT wash gel pillows or gel-infused foam - water irreversibly damages materials. Remove and wash pillow cover according to care label (typically machine washable). Spot clean outer pillow with damp cloth and mild detergent for stains. Avoid saturating foam or gel components. Professional cleaning not recommended.
Drying Instructions:
If spot cleaned, air dry completely in well-ventilated area away from direct heat and sunlight. Never place in dryer - heat damages gel properties and foam structure. Ensure complete drying before replacing cover to prevent mold and mildew. May take 24-48 hours.
Maintenance Tips:
- •Use removable, washable pillow protector to shield from body oils, sweat, and moisture
- •Air out monthly by removing cover and placing in ventilated area for 2-3 hours
- •Rotate pillow 180 degrees every 2-3 weeks to ensure even wear and compression
Horsehair
Washable:
Washing Instructions:
NOT MACHINE WASHABLE. Horsehair pillows cannot be washed in machines as water and agitation damage the natural curl and resilience of the fibers. Spot clean only with damp cloth and mild soap for stains. The processed horsehair itself is inherently clean and antimicrobial after high-temperature steaming, so washing is rarely necessary.
Drying Instructions:
If pillow becomes damp from spot cleaning or humidity, air dry completely in well-ventilated area before use. Horsehair dries remarkably quickly due to water-repellent properties - when soaked and shaken, it dries almost immediately. Never use heat sources like dryers which damage fiber structure. Ensure 100% dryness before returning to bed.
Maintenance Tips:
- •Air out pillow outdoors in fresh air and indirect sunlight monthly for 2-3 hours to eliminate any trapped moisture
- •Fluff daily by grabbing opposite corners and shaking vigorously to redistribute fibers and maintain loft
- •Use tightly woven pillow protector (200+ thread count) to prevent coarse hairs from poking through fabric

Durability & Longevity Factors
Gel
Factors Affecting Lifespan:
- •Quality of gel material - medical-grade thermoplastic gel lasts longer than cheap alternatives
- •Gel concentration in infused foam - higher gel content (15-30%) performs better over time
- •Foam base quality - CertiPUR-US certified high-density foam extends overall lifespan
- •Seal integrity on gel layers - poor sealing leads to premature leaks and failure
- •Usage frequency and sleeper body weight affecting compression rate
- •Storage conditions - extreme temperatures degrade gel properties faster
- •Quality of cover material - durable, breathable covers protect internal components
Horsehair
Factors Affecting Lifespan:
- •Quality of horsehair processing - properly steamed and cleaned hair lasts significantly longer
- •Distinction between horsehair and horsetail - horsetail (from tail) is longer, stronger, springier and more durable
- •Quality of cover ticking - tightly woven fabric prevents fiber migration and protects fill integrity
- •Frequency of airing and maintenance - regular outdoor airing prevents moisture buildup extending lifespan
- •Storage conditions - keeping pillow in dry, well-ventilated environment prevents deterioration
- •Manufacturing quality - hand-teased loose horsehair outlasts cheaper rolled horsehair pads
- •Combination with other materials - pure horsehair often more durable than blends with shorter-lived fibers
Environmental Impact & Sustainability
Gel
Sustainability:
Poor environmental profile. Gel pillows contain multiple petroleum-based synthetic materials including polyurethane foam and thermoplastic gel compounds. Manufacturing processes are energy-intensive requiring chemical synthesis, heat, and pressure. Gel production uses mineral oil and styrene derived from fossil fuels. Short lifespan (2-4 years) results in frequent replacement and waste. Non-biodegradable materials persist in landfills for centuries. Heavy weight increases transportation emissions. No practical recycling options - gel and foam bonded together prevent material separation.
Biodegradable:
Manufacturing:
Complex manufacturing involving multiple petroleum-derived materials and chemical processes. Polyurethane foam produced through polymerization reactions requiring isocyanates and polyols. Gel manufactured through synthesis of styrene copolymers or polyurethane combined with plasticizers and mineral oil. Energy-intensive production with significant carbon emissions. Gel infusion requires additional processing steps incorporating gel beads into foam. Quality control critical to prevent gel separation and uneven distribution. Most production occurs overseas with varying environmental standards.
Horsehair
Sustainability:
Highly sustainable when sourced from reputable manufacturers practicing ethical collection. Horsehair is gathered during routine grooming that horses require anyway for health and hygiene - the mane and tail are trimmed regularly whether hair is collected or not. No horses are farmed specifically for hair production by ethical manufacturers. Quality suppliers verify horsehair is "acquired at the end of life" or from regular grooming, never from living horses farmed for hair. The material utilizes what would otherwise be grooming waste, creating beneficial circular economy. Processing requires only water and steam - no chemical treatments or energy-intensive manufacturing. Horses are not harmed, distressed, or killed for hair collection by ethical producers.
Biodegradable:
Manufacturing:
Relatively low environmental impact for luxury material. Processing involves washing in boiling water, steaming at 284°F at four times atmospheric pressure, rinsing, spinning, and natural drying. The entire process uses only water and heat - no chemical additives, bleaching, or synthetic treatments. Traditional hand-teasing methods (separating and curling individual fibers) are labor-intensive but require no machinery beyond basic equipment. Most environmental impact comes from transportation and the labor hours (150-160 hours for premium mattresses). At end of exceptionally long 20-40+ year lifespan, horsehair is completely biodegradable and decomposes naturally, returning nutrients to soil. The extended lifespan significantly reduces replacement frequency compared to synthetic alternatives lasting 2-5 years, ultimately reducing long-term environmental burden despite higher initial resource investment.
