Description
Temperature Regulation Built Into Your Mattress Protection Layer
The Velfont Frost Mattress Protector applies Outlast® thermoregulating technology to the mattress protection layer — bringing NASA-developed phase change material (PCM) temperature management to the surface directly in contact with the mattress. Made entirely from 100% Outlast® thermoregulating cotton, the Frost protects the mattress from dirt, dust mites, and wear while simultaneously creating a thermoregulating buffer between the mattress and sleeping surface that regulates temperature fluctuations throughout the night. For those who experience overheating, night sweats, or temperature-related sleep disruption, the Frost addresses the problem at the mattress surface level rather than relying on bedding above it alone.
Outlast® PCM Technology — The Same NASA-Developed System as the Velfont Fresh
The Frost uses the same Outlast® phase change material technology found in Velfont’s Fresh fitted sheet — natural wax microcapsules printed onto 100% cotton that react to body temperature by transitioning between solid and liquid states, absorbing and releasing heat to maintain a constant personalised microclimate.
When body temperature rises during sleep — through the active phases of the sleep cycle, warm room conditions, or hormonal fluctuations — the PCM microcapsules absorb the excess heat by melting. When body temperature drops, the solidifying microcapsules release the stored heat back. This continuous cycle repeats throughout the night, buffering both upward and downward temperature swings and preventing the temperature extremes that disrupt sleep.
The practical results of Outlast® thermoregulation in a mattress protector: less sweating at the skin surface, fewer nighttime wake-ups due to overheating or sudden cold, and a consistently comfortable sleeping environment across the full duration of the night. The technology is dermatologically tested, skin-friendly, and wash-resistant — the PCM properties are maintained through repeated washing.
Non-Waterproof — Maximum Breathability for Temperature-Sensitive Sleepers
The Frost is a non-waterproof protector — it does not contain a polyurethane membrane. This is a specific and deliberate choice for its intended customer: those whose primary concern is temperature management rather than liquid protection.
A waterproof membrane, however breathable, always adds some resistance to moisture vapour transmission compared to a membrane-free fabric. For those with intense night sweats or strong temperature sensitivity, this difference matters — the Frost’s membrane-free construction allows maximum breathability and unrestricted vapour permeability, ensuring that perspiration dissipates as freely as possible through the protection layer. The Outlast® cotton does the protective work through temperature absorption and release rather than liquid blocking.
For those who need both temperature regulation and liquid protection, Velfont’s waterproof thermoregulating range (the Alaska model) combines the Outlast® fabric with a waterproof membrane — but the Frost’s non-waterproof design makes it the preferred choice specifically for those prioritising thermal comfort above all else.
Anti-Allergenic, Antibacterial, and Anti-Dust Mite
Despite containing no waterproof membrane, the Frost provides meaningful hygienic protection through its cotton construction and fitted format. The elasticated fitted sheet profile physically covers and encloses the mattress surface, acting as a barrier that prevents dust mites, skin cells, and particulate matter from accumulating directly on the mattress. The Outlast® cotton’s moisture management — reducing the humid microclimate that mites and bacteria prefer — reinforces this biological protection without chemical treatment.
The Frost is certified anti-allergenic, antibacterial, and suitable for allergy sufferers. OEKO-TEX® Standard 100certification confirms that all components are free from substances harmful to health
The Complete Outlast® System — Frost and Fresh Together
The Frost and Fresh are designed as complementary layers of the same Velfont thermoregulating system. The Frost sits on the mattress surface — applying Outlast® temperature management at the base of the sleep environment. The Fresh fitted sheet sits above the Frost — applying Outlast® temperature management at the direct skin-contact surface. Used together, the two layers create a full Outlast® thermoregulating system around the sleeper, with both the mattress side and the skin side actively managing temperature throughout the night.
Velfont specifically notes that layering thermoregulating products amplifies the system’s effectiveness — the Frost and Fresh together provide significantly more thermoregulating capacity than either layer alone.
Fitted Sheet Format — Fits Mattresses Up to 35cm
The Frost protects the mattress in a practical and comfortable way, fitting exactly like a fitted sheet. Elasticated all around the perimeter for a secure fit throughout the night. Fits mattress lengths up to 200cm and heights up to 35cm — slightly deeper than the Fresh fitted sheet, accommodating thicker mattress-plus-topper combinations.
Washable at 40°C. No fabric softener. Air dry or tumble dry on the lowest setting only. Made in Spain by Velfont (founded 1971, Barcelona).

FAQ:
Q: What is the difference between the Velfont Frost mattress protector and the Velfont Fresh fitted sheet — do I need both?
The Frost and Fresh serve different functions in the sleep system — and using them together is Velfont’s own recommendation for maximum thermoregulating effectiveness.
The Frost is a mattress protector: it envelops the mattress like a fitted sheet and sits between the mattress and the sleeping surface above. It protects the mattress from dust, mites, and wear while applying Outlast® thermoregulation at the mattress level — creating a thermoregulating base to the sleep environment.
The Fresh is a fitted sheet: it sits directly above the Frost (or above the mattress protector) and is the surface in direct skin contact throughout the night. It applies Outlast® thermoregulation at the skin-contact level — the most immediate and direct point of temperature management.
Used alone, either layer provides thermoregulating benefit. Used together, they create a complete Outlast® thermoregulating system — temperature is actively managed both at the mattress surface (Frost) and at the skin surface (Fresh) simultaneously. Velfont specifically notes that layering thermoregulating products amplifies the overall thermal comfort. For those with significant night sweating or strong heat sensitivity, the combined system is meaningfully more effective than either product alone.

Q: Why choose a non-waterproof thermoregulating protector — what do I sacrifice without a membrane?
The absence of a waterproof membrane is a deliberate engineering decision for a specific type of sleeper — not an omission. Understanding the trade-off helps identify whether the Frost is the right choice.
A waterproof membrane provides complete liquid protection — preventing any spill, sweat accumulation, or nocturnal accident from reaching the mattress. This is valuable for families with young children, pets, or anyone with incontinence concerns. However, even the most breathable membranes add some resistance to moisture vapour transmission compared to a membrane-free fabric.
For those whose primary concern is temperature regulation — particularly heavy night sweaters, those managing menopause symptoms, or heat-sensitive sleepers — the Frost’s membrane-free construction allows the maximum possible breathability. Perspiration vapour dissipates through the cotton fabric with no membrane resistance at all. The Outlast® thermoregulating cotton also works more efficiently without a membrane layer interrupting the heat exchange at the mattress surface.
Choose the Frost if temperature management is the priority and liquid protection is not a primary concern. Choose the Velfont Vital or Aura if both liquid protection and thermoregulation are needed simultaneously.
Q: Does the Frost physically protect against dust mites even without a chemical treatment or membrane?
Yes — the Frost provides meaningful dust mite protection through two mechanisms, neither of which requires a chemical treatment or waterproof membrane.
First, the fitted sheet format provides a physical barrier: the elasticated cotton covers the entire mattress surface and tucks under the edges, preventing dust mites from migrating between the mattress interior and the sleeping environment above. This is the same principle used by all fitted-format protectors — the coverage itself reduces mite access and accumulation on the mattress.
Second, the Outlast® cotton’s moisture management reduces the humid microclimate that dust mites require to survive and reproduce. Mites thrive in warm, moist environments — the Frost’s active temperature absorption reduces both the heat and moisture accumulation at the mattress surface, creating an environment that is less hospitable to mite colonisation over time.
For those with confirmed dust mite allergy requiring clinically certified chemical anti-mite treatment, the Velfont Vital protector — with its Acarsan® Natural plant-extract anti-mite treatment tested by TEC and certified by SEAIC and Allergy UK — provides the more rigorous solution. The Frost’s mite protection is physically and climatically based rather than chemically certified.
Q: The Velfont Frost costs more than standard non-waterproof mattress protectors — what justifies the price?
The price reflects the single specific distinction that separates the Frost from every standard cotton mattress protector: the Outlast® thermoregulating PCM treatment applied to the cotton fabric.
A standard non-waterproof cotton mattress protector is simply cotton fabric in a fitted sheet format — it provides physical coverage and basic hygiene protection. The material cost is cotton and elastic. The Frost begins with the same cotton base and adds Outlast® PCM microcapsule technology — a licensed, NASA-developed system with Space Foundation certification — to the fabric. This treatment and licensing represents a material cost premium over standard cotton that is directly proportional to the functional difference it delivers.
The functional difference is specific and measurable: a standard cotton protector covers the mattress. The Frost covers the mattress and actively buffers body temperature fluctuations throughout the night, reducing night sweating and maintaining sleep continuity for heat-sensitive sleepers. For those who regularly experience temperature-related sleep disruption, this function is a genuine sleep quality improvement — not a marginal comfort enhancement.
OEKO-TEX® Standard 100 certification, Spanish manufacturing by Velfont since 1971, and free delivery in Tbilisi complete the picture of a product whose price premium is fully accounted for by its thermoregulating technology.
