Couple: improve your sleep with Climsom cooling/heating mattress toppers



Climsom knows that temperature is an essential part of comfortable sleep.
The management of heating and temperature in the bedroom is often a bone of contention in a couple.
When one is too hot and only wants a sheet, the other is freezing and wants to wrap himself in a thick duvet.

With Climsom Duo, in a bed with two people, each person can keep his or her own comfort temperature.
You will finally be able to choose your own comfort temperature without imposing it on your partner, whatever the temperature of the room, and whatever the size of your bed.

- In summertime, CLIMSOM eliminates excess heat and night sweats. You'll finally be in control of your nights again.
- CLIMSOM helps you say goodbye to icy beds and cold hands and feet in the winter.
- CLIMSOM can supplement or even replace bedroom air conditioning or heating.
- It's the only healthy and safe alternative to electric blankets.

With the cooling/heating Climsom Duo mattress toppers, sleep at the right temperature, anytime, in any season.
CLIMSOM installation takes just a few minutes, and it's easy to use.
Simply pour water into the tank of each water thermocontroller and choose your comfort temperature: Climsom takes care of the rest. The water, cooled or heated according to your request, from 18° to 48°C (64° to 118°F), circulates in the mattress topper through silicone tubes - they are so thin that you won't feel them! - to condition the surface of your bed.

While it is recommended to sleep in a room heated between 16° and 18°C, it is essential to make a distinction between the temperature of a room situated between 16° and 18°C, and the temperature of body contact with a surface at 18°C.
For example, we have all had the experience of diving into seawater at 18°C... And it is much more striking than entering a room at the same temperature!

The heat exchange between your body and the water is much greater than the one between your body and the surrounding air.
So a water-conditioned mattress topper with water at 18°C will actually cool your body.

It is up to each person to determine his or her personal comfort temperature when using a water-conditioned mattress topper, in order to maximise the quality of sleep.


French Professor Damien Léger, from the Sleep and Vigilance Centre of the Hotel-Dieu (Paris, France) and Climsom have conducted the first pilot study on the link between sleep quality and the temperature of the immediate sleep environment: the bed.
Here are the main results and benefits of the Climsom water-conditioned mattress topper:

  • Improving the quality of the night: + 58%
  • Dynamism when waking up: +48%
  • Improving the quality of the day: + 19%
  • Quieter nights: -24,5% of night-time movements
  • Increased sleep time: +23 minutes


CLIMSOM improves your sleep
Tossing and turning all night and difficult mornings are things of the past.
Learn how your controlled personal comfort temperature promotes healthy sleep and easier waking.
Say goodbye to your sleep disorders, such as :
- Difficulty falling asleep and waking up at night
- Hot flashes due to menopause.
- Hyperhidrosis: excessive night sweating. This affects all age groups. For the elderly, excessive night sweating can aggravate the frequent problem of dehydration.

CLIMSOM relieves pain
- Heavy legs: the cooler settings provide a triple physiological effect (anti-inflammatory, vasoconstrictive and analgesic) that provides quick, all-night relief from pain and stimulated blood circulation.
Restless Legs Syndrome (Willis-Ekbom disease): a cool temperature can help relieve 75 percent of RLS cases. Muscle aches and pains: Heat quickly and effectively relaxes sore backs and muscles.
- Lumbago/back pain: use CLIMSOM’s pleasurable, efficient heating to relax and soothe the pain with thermo-therapy.
Heating brought by circulating water is far more penetrating and soothing than any other means such as electric blanket or the like.

- Freshness is also an ally for slimming diets: by activating brown fats (brown adipose tissue), which in turn consumes white fat.

- The heat relieves back pain, lower back pain and Raynaud's syndrome.
It is also a good way to keep your feet warm during the winter!


The Climsom water-conditioned mattress topper is very thin and fits all bedding.
It only takes a few minutes to install your CLIMSOM. And it's very user-friendly !

The mattress topper is placed under your fitted sheet. As for the thermocontroller itself, it is placed under your bed.
Your remote control enables you to program your Climsom cooling/heating mattress topper without leaving your bed!



A UK plug adapter is included for UK delivery.

The CLIMSOM project was born from a meeting between the founders of NEO FACTORY and Dr. Tamburini. A French phlebotomist for over 25 years, Dr. Tamburini has seen patients suffering from sleep disorders due to venous insufficiency and impatient legs. He then had the idea and the dream of conditioning a bed to provide lasting relief for his patients. From 2005, with Dr Philippe Tamburini and the help of the NEO FACTORY team, the project gradually took shape.

This is how the CLIMSOM mattress topper was born, with an official launch in 2009. It met with a large public, meeting various needs beyond the initial project: sleep disorders, heavy legs, night sweating, restless legs, hot flashes, night comfort, back pain...
