WHY YOU'LL LOVE
The PolyCool™ Cooling Mattress Topper?
Your PolyCool™

Continuous temperature regulation
The PolyCool™ Cooling Mattress Topper effectively balances your temperature fluctuations throughout the night. When your body warms up, its Kulkote® technology is activated and immediately regulates the temperature of your sleeping surface. This advanced technology helps to keep you cool at all times!

Adjustable cooling
Your PolyCool™ can be flipped upside down, or stay right side up to decrease or increase the level of cooling. Since we all react to temperature differently, your PolyCool™ comes in two separate sheets (Queen +) so both you and your partner can enjoy different cooling levels if need be.

Protects your mattress over time
Made from our antimicrobial hybrid foam, the PolyCool™ actively protects your mattress against bacterial growth. This also helps to extend the life of your mattress!

Both your body temperature and your bedroom's temperature greatly influence the quality of your sleep.
If you suffer from night sweats or tend to get hot at certain times of the year, the PolyCool™ Cooling Mattress Topper is designed for you.
The KulKote® coating senses and regulates your temperature changes throughout the night to give your mattress the perfect level of comfort you need.


The KulKote® technology built into the PolyCool™ Cooling Mattress Topper is similar to that used in space suits to regulate astronauts' temperatures! It absorbs and releases thermal energy to maintain an optimal sleeping temperature.
How does it work?
KulKote® is a water-based polymer coating applied to the surface of our hybrid foam; it uses micro-capsules that continuously change from liquid to solid phase to effectively manage thermal energy.
A simulation conducted by the University of Auckland reveals that a person sleeping on a sleeping surface incorporating Kulkote® technology, maintained a constant temperature of 29°C for 22 consecutive hours. Under similar conditions, we observe strong temperature variations and a sleeping surface that reaches 35°C without Kulkote® technology.


Just like other Polysleep products, the PolyCool™ hybrid foam is certified antimicrobial.
It acts as a protective barrier against the accumulation of bacteria and germs inside your mattress. You'll greatly reduce your risk of allergies and enjoy a healthier sleeping surface.


If you want to feel less cooling, you can place your PolyCool™ under your mattress protector or mattress cover. This will help to reduce the level of cooling sensation.
For the lowest amount of cooling, your PolyCool™ is reversible. Simply flip it over to the other side, both sides have different levels of cooling.
If you want the most cooling sensation possible, you can place it directly under your fitted sheet.


Our comfort needs can sometimes differ from those of our sleeping partner. Don't worry, we've thought of everything!
Our cooling mattress topper detaches into two parts in sizes Queen +
If your partner prefers a warmer surface, they can flip over their PolyCool™ for the less-cooling side. They still enjoy an extra touch of comfort thanks to the softness of our hybrid foam.
-
Remove the PolyCool™ from its box, use scissors and not a knife to avoid damaging it by opening its protective packaging.
Remove your sheets, pillows or mattress protector from your sleeping surface. Mattress protectors can be placed on top or underneath your PolyCool™ depending on the level of cooling you are looking for.
Make sure it is placed evenly and flatten any creases. Once the topper is perfectly flat, replace your bedding. -
Yes, the PolyCool™ is suitable for all types of mattresses.
In addition to bringing you an immediate feeling of freshness, it brings a light softness to your sleeping surface for even more comfort!
It's important to know that if your mattress is caved-in, the overlay will take the shape of your body where the hollow space is present with time. -
Absolutely! Kulkote® technology has no off-gassing or harmful chemicals and uses 100% wated-based coatings.
