THE HEAT FROM BELOW
The other half of the heat comes from underneath.
A cooling blanket takes care of the heat above you. But you also lie on a mattress for eight hours, and foam is built to hold warmth. In a heated bedroom in winter, a thick mattress and a warm duvet can sandwich you in heat from both sides.
Napfull Base™ adds a cool-to-the-touch layer between you and the mattress, so warmth has somewhere to go instead of pooling beneath you.
HOW IT WORKS
A cooler bed climate starts at the bottom.
Sleep researchers call the thin layer of air around you the bed climate. It’s shaped from above by your blanket, and from below by your mattress.
Cool-touch top
Draws warmth away from your skin (Qmax 0.40–0.45) instead of letting it build up under you.
Thin waterproof layer
Keeps sweat and spills out of the mattress, without a thick plastic sheet.
Elastic skirt
Stays in place on mattresses and toppers.
WHO IT’S FOR
For the heat you can’t throw off
Which size is right for you?
MEASURED, NOT PROMISED
Cool you can measure: Qmax 0.40–0.45.
Qmax measures how much heat a fabric draws from your skin the moment you touch it. Around 0.15 W/cm² is where fabric starts to feel cool. Napfull’s cooling fabric measures 0.40–0.45 — close to three times that line.
Under a fitted sheet you’ll feel it less directly than on the blanket. What stays the same is that the layer under you draws warmth away instead of storing it.
Qmax measured on Napfull fabric, [LAB NAME, YEAR]. Cool-feeling threshold per GB/T 35263-2017.
Against an ordinary mattress protector
Most protectors protect the mattress. This one also thinks about you.

Does it help with night sweats?
Does it help with night sweats?
It can’t stop a hot flash, and nothing you sleep on can. What it does is keep moisture out of your mattress and give you a cooler surface to lie on. If night sweats are new, heavy or come without a known reason, talk to your doctor.
