Description
For many people, temperature is the single biggest disruptor of sleep. Overheating causes restlessness, excessive sweating pulls the body out of deep sleep, and the fluctuations between too warm and too cool repeat throughout the night without the sleeper ever fully understanding why they wake up feeling unrested. The Velfont Frost mattress protector is designed to resolve this — not by cooling the mattress passively, but by actively regulating temperature in response to the body’s own heat output.
The Frost is made from 100% Outlast® thermoregulating cotton — a material whose origins lie in NASA research into protecting astronauts from the extreme temperature variations of space. The technology works through millions of phase-change microcapsules embedded directly into the cotton fabric. As the body warms during sleep, these microcapsules absorb the excess heat and store it in a liquid state. As the body cools — between sleep cycles, or as the night temperature drops — the microcapsules release the stored heat back, returning to a solid state. This process repeats continuously and automatically throughout the night, creating a stable, personalised microclimate that never swings too far in either direction.
The practical result is a sleeping surface that feels neither warm nor cold — simply comfortable — regardless of the season, the room temperature, or the sleeper’s individual tendency to overheat. For people who sweat at night, who use memory foam or viscoelastic mattresses that retain heat, or who experience hormonal temperature fluctuations such as those associated with menopause, the Frost is among the most targeted solutions available in mattress protection.
Beyond its thermoregulating performance, the Frost functions as a complete mattress protector. Its breathable cotton construction promotes air circulation through the mattress, preventing the accumulation of humidity that can degrade mattress materials over time. It is anti-allergenic and antibacterial, depriving dust mites of the humid conditions they require. It fits in the standard fitted-sheet format, with an elasticated border that adjusts to mattress lengths up to 200cm and heights up to 35cm — compatible with all mattress types including memory foam, latex, and pocket spring.
The Outlast® thermoregulating performance is wash-resistant, maintaining its effectiveness through regular laundering. Washable at 40°C, skin-friendly, and dermatologically tested, the Frost is a practical product as well as an intelligent one. It pairs naturally with the matching Velfont Frost pillow protector and Fresh fitted sheet to create a complete thermoregulating sleep system across the entire bed surface. Made in Spain.
