Thermo-regulating mattress: your ally for a cool night's sleep in summer?

Have you ever woken up sweating in the middle of the night, wishing you could turn off the heat like a light? Sleeping cool is not just about comfort, it's about health and wellbeing. A thermo-regulating mattress can make all the difference on those hot nights, helping you rest deep and refreshed.

Introduction: Night heat and sleep quality with thermo-regulating mattresses

During the summer, the heat hinders the body's ability to regulate its temperature, leading to insomnia, night-time awakenings and constant sweating. Choosing a thermo-regulating mattress or a cooling mattress is not just a question of comfort: it is essential to maintain optimal sleep quality and to know how to sleep in the heat without interruptions.

What is a thermo-regulating mattress and how does it help you sleep cool?

Functioning of the thermo-regulating mattress for heat control

Thermo-regulating mattresses work by combining various technologies and materials designed to dissipate heat, control humidity and promote continuous ventilation:

1. Gels and graphene
   They incorporate viscoelastic foams with graphene or gel particles that absorb excess body heat and disperse it quickly, providing a cool sensation to the touch.
2. PCM Microcapsules (Phase Change Material)
   These microcapsules act as intelligent thermal regulators that absorb heat when body temperature rises and release it when it falls, maintaining a constant microclimate throughout the night.
3. Open-cell foam structures, convolutions and perforations
   Open cell foams, contoured cuts and perforations allow air circulation, eliminating the feeling of trapped heat and contributing to a cooler environment.
4. Springs or pocket springs (in hybrid models)
   The springs create ventilation spaces that complete the thermal regulation, adding structural support and long-lasting coolness.
5. Breathable fabrics such as Tencel or Outlast®.
   Covers with natural fibres or special technologies improve moisture evaporation and keep the skin in contact with cool, dry fabrics.
6. Thermal and zonal adaptability
   Some mattresses have thermal zoning to adjust the temperature on each side, ideal for couples with different needs.

These combined technologies allow for a deeper sleep, uninterrupted by heat or perspiration, and are particularly effective for those looking for a way to sleep in warmth without sacrificing comfort.

Benefits of sleeping on a thermo-regulating and cool mattress

• Deeper and more restful sleep: prevents overheating to facilitate access to REM phases.
• Zero night sweats: ideal for people with excessive sweating.
• Increased comfort when waking up: a feeling of freshness and well-being.

Natural materials that help regulate temperature in thermo-regulating mattresses

Organic cotton and other vegetable fibres

Organic cotton, linen, jute or coconut fibre are highly breathable, control moisture and maintain a cool microclimate. They are also biodegradable, hypoallergenic and grown without pesticides. Find out more about certified organic cotton.

Natural latex and its ventilation capacity

Natural latex has a cellular structure that allows air to pass through, preventing heat build-up. It is durable, ergonomic and naturally hygienic.

Tips for keeping your thermo-regulating mattress cool in summer

• Use a thermo-regulating topper or protector, made of gel or cool cotton.
• Ventilate the bed a few minutes before going to bed.
• Choose light cotton or linen bedding.
• Keep the room between 19-22 °C.
• Use a fan or air conditioning, avoiding direct contact with the mattress.

Are thermoregulating mattresses sustainable?

At Wonderflip, we believe that sleep should not compromise the future of the planet. That is why it is essential to differentiate between truly sustainable technologies and others that, although thermally effective, can damage the environment.

Sustainable technologies that we do recommend for thermoregulating mattresses

• Natural latexRenewable, biodegradable and certified (GOLS, Oeko-Tex).
• Organic cotton, flax, hemp and other plant fibresbreathable and pesticide-free.
• Tencel™.Fibre produced with low environmental impact and high thermal regulation capacity.
• Certified fabrics (Oeko-Tex®)guarantee the absence of toxic substances.

Unsustainable technologies to avoid in your thermo-regulating mattress

• Viscoelastic foams with gel or graphene: petroleum-derived, difficult to recycle and polluting.
• Conventional PCM microcapsulesMostly synthetic, non-biodegradable and non-recyclable.
• Open cell polyurethane foamsPlastics with a high carbon footprint.

Conditions for a thermoregulating mattress to be sustainable

• Use of certified biodegradable or recyclable materials.
• Manufacturing with renewable energy and clean processes.
• Recycling and post-use collection programmes.
• Guaranteed durability (minimum 10 years).
• Transparency and environmental commitment of the brand.
