FAQ

What makes Frostelle pillowcases different?

Frostelle combines 100% Eucalyptus Lyocell with advanced PCM (Phase Change Material) cooling technology, creating a dual-cooling system that regulates heat, balances temperature, and keeps you comfortable all night. It’s scientifically tested to outperform cotton and silk in cooling performance.

 

What is PCM and how does it work?

PCM stands for Phase Change Materials - microscopic capsules applied to the fabric that absorb excess heat when you’re warm and release it when you cool down.

This keeps your sleep temperature stable, reduces overheating, and delivers a continuous cooling effect.

Are your pillowcases really lab-tested?

Yes. Frostelle fabric has been tested under GB/T 35263–2017, the standard for measuring textile cooling sensation.

Our results show a Q.max score of 0.26, significantly above the cooling threshold of 0.15 - confirming strong, instant cooling performance.

Do Frostelle pillowcases help with night sweats?

Yes. PCM reduces heat build-up, while Lyocell naturally wicks moisture and improves airflow. Together, they help regulate temperature and keep you dry, cool, and comfortable.

Are Frostelle pillowcases good for acne-prone or sensitive skin?

Absolutely. Lyocell is naturally hypoallergenic, smooth, and less absorbent than cotton, meaning fewer oils and bacteria sit on the fabric. This creates a cleaner surface that’s gentler on sensitive and breakout-prone skin.

What size is the pillowcase and will it fit my pillow?

Frostelle pillowcases use a tailored 47 × 73 cm design to prevent the bagginess of standard 50 × 75 cm cases.

This size fits all standard UK pillows but creates a cleaner, more snug fit.

Why is the pillowcase cooler than silk or cotton?

Silk traps heat and cotton absorbs moisture.

Frostelle uses:

• PCM technology for temperature regulation
• Lyocell for heat + moisture dispersion
• The two together provide a superior cooling experience.

How do I wash my Frostelle pillowcase?

Machine wash cold (30°C) with mild detergent.

Avoid bleach and fabric softeners.

Air dry or tumble dry on low.

These steps protect the PCM cooling finish and maintain long-term performance.

Is PCM safe?

Yes. PCM microcapsules are dermatologically safe, non-toxic, and commonly used in medical textiles, bedding, and high-performance apparel.

Can Frostelle help me sleep better?

Yes - many customers report:

• Falling asleep faster
• Fewer night-time awakenings
• Reduced overheating
• A fresher, cleaner sleep environment
• Temperature regulation is proven to improve overall sleep quality, and Frostelle is engineered for exactly that.
