Description
Performance Sleep Engineering from Italy
Dorelan designs the Active Topper 4.5cm for those who demand more from their sleep surface. At 4.5cm, it delivers a substantial improvement to any mattress in good condition — combining gentle pressure relief, active breathability, and precise thermoregulation in a single removable layer. Dorelan has been crafting technically advanced sleep products in Italy for over 50 years, and the Active Topper is a clear expression of that expertise. Explore our full topper collection → toppers
Myform Memory Air — Italian Memory Foam Engineered for Ventilation
The core of this topper uses Myform Memory Air — Dorelan’s proprietary open-cell memory foam with an alveolar (honeycomb) structure. Standard memory foam tends to trap heat and restrict airflow. Myform Memory Air addresses both problems simultaneously.
Its open-cell structure promotes active heat dispersion throughout the foam layer rather than accumulating warmth at the surface. The alveolar architecture allows air to circulate freely as the foam compresses and recovers with your movements. The result is memory foam that envelops and relieves pressure precisely — while maintaining a cooler, drier sleeping environment than conventional memory foam delivers.
The foam adapts precisely to your body’s weight and shape, relieving pressure points at shoulders, hips, and knees, and maintaining that adaptation consistently throughout the night.
CoolNight Cover — Active Thermoregulation
Dorelan covers this topper in CoolNight fabric — a technically engineered textile with advanced thermoregulating properties. CoolNight actively responds to body heat, absorbing excess warmth and dispersing it rather than allowing it to accumulate at the surface.
The cover provides precise and stable climate management throughout the night — keeping the sleeping microclimate consistently fresh regardless of the season or sleeping intensity. The three-dimensional Re:search base fabric on the underside ensures grip, stability, and additional breathability.
The cover is fully removable via a perimeter zip and machine washable — making routine hygiene maintenance straightforward and convenient.
Ideal Use & Care
The Active Topper suits any sleeper who wants pressure relief and temperature regulation from their sleeping surface — and is particularly well suited to active individuals whose bodies generate more heat during recovery sleep. Place it on any mattress in good condition. Secure the topper with the elastic corner straps to prevent shifting during the night.
Remove the cover by unzipping the perimeter zip and machine wash as needed. Follow the care label temperature guidance. Never machine wash the foam core — spot clean with a damp cloth and air dry thoroughly. Compare with our TEMPUR® topper options → TEMPUR topper One 5cm

FAQ
Q: What is Myform Memory Air and how does it differ from standard memory foam?
Myform Memory Air is Dorelan’s proprietary open-cell memory foam — and it solves the two most common complaints about standard memory foam: heat retention and sluggish response.
Standard memory foam uses a closed-cell structure that traps heat and recovers slowly after compression. Myform Memory Air uses an alveolar (honeycomb) open-cell structure that actively promotes heat dispersion throughout the foam layer. Air circulates freely as the foam compresses and recovers with your movements — preventing the heat build-up that makes conventional memory foam uncomfortable for warm sleepers.
The foam retains all the pressure-relieving properties that make memory foam valuable — adapting precisely to body weight and shape, relieving pressure points at shoulders, hips, and knees — while adding the breathability and temperature management that standard memory foam lacks.
Q: How does CoolNight fabric work and is this topper genuinely suitable for warm sleepers?
CoolNight is a technically engineered thermoregulating fabric — and it actively manages heat rather than simply using a breathable weave.
The fabric responds to body heat, absorbing excess warmth at the surface and dispersing it rather than allowing it to accumulate. This maintains a precise and stable microclimate throughout the night — keeping the surface consistently fresh even during periods of higher body heat generation.
For warm sleepers, the combination of CoolNight cover and Myform Memory Air core addresses the problem at two levels simultaneously — the cover manages surface heat, while the foam’s open-cell structure prevents heat retention within the material itself. This dual approach makes the Active Topper meaningfully more effective for warm sleepers than a standard memory foam topper with a generic cover. Learn more about Dorelan → https://www.dorelan.com
Q: Can I use the Dorelan Active Topper on any mattress, or does it need to be used with a specific Dorelan mattress?
The Active Topper works on any mattress in good structural condition — it does not require a specific Dorelan mattress beneath it.
The elastic corner straps secure the topper firmly to the mattress beneath, preventing shifting during the night regardless of the mattress type. The Re:search three-dimensional base fabric on the underside adds grip and stability, further ensuring the topper stays in place.
For best results, the mattress beneath should be in good condition — structurally sound without deep sagging or significant indentations. A topper placed on a worn-out mattress follows the contours of the damage rather than correcting them.

Q: How do I care for the Dorelan Active Topper?
Care is straightforward — the key rule is to wash only the cover, never the foam core.
Unzip the perimeter zip to remove the cover fully. Machine wash the cover following the temperature guidance on the care label. The cover dries relatively quickly and can be air dried or tumble dried on low heat.
Never machine wash or soak the Myform Memory Air foam core — doing so causes irreversible damage to the foam structure. Spot clean the foam with a damp cloth if needed and allow it to air dry completely before replacing the cover. Air the foam regularly in a well-ventilated space to maintain freshness. A topper protector placed over the Active Topper reduces how often the cover needs washing and extends the foam’s lifespan.
Q: The Dorelan Active Topper costs more than basic memory foam toppers — what makes it worth the investment?
The price difference reflects genuine technical distinctions — not simply brand positioning.
The core difference is the foam itself. Myform Memory Air is not standard polyester memory foam — it is an engineered open-cell alveolar structure developed and manufactured by Dorelan in Italy. Producing an open-cell foam with consistent alveolar architecture, a density of 52kg/m³, and reliable shape retention over time is technically more demanding and more expensive than producing commodity memory foam. The performance difference — in breathability, heat management, and pressure relief precision — is measurable and immediately felt.
The CoolNight cover adds a second layer of genuine differentiation. Most basic memory foam toppers use a standard knit cover that simply does not restrict airflow. CoolNight actively responds to and manages body heat — a meaningful engineering investment that directly improves sleeping comfort for warm sleepers.
Dorelan also holds the first hygiene certification in the Italian bedding industry — guaranteeing hygiene standards at every stage of manufacturing, from raw material sourcing to delivery. For a product in direct contact with your skin every night, that certification carries real weight.
Finally, Italian craftsmanship and quality control standards. Dorelan manufactures in Italy with material and production standards that mass-market foam toppers produced at volume in lower-cost markets simply cannot match.
