Why 123 ？
At 123, we believe sleep is more than a basic necessity it’s a powerful journey for both body and mind. Scientific research supports this belief. According to renowned neuroscientist Andrew Huberman of Stanford University, maintaining a cool sleeping environment (around 18°C–22°C) is one of the most important factors for achieving deep, restorative sleep. Our innovation is built around this principle not simply making you cold, but creating your perfect comfort zone throughout the night.
Meanwhile we realized sleep technology shouldn’t be reserved for elite athletes or “sleep fitness” enthusiasts. It should empower couples with different sleep temperatures, shift workers sleeping through summer heat, professionals needing sharper focus, and anyone without A/C in their bedroom. 123 sleep was designed to help everyone sleep deeper, recover faster, and wake with more energy.
Frequently Asked Questions
How does the Mattress work,and how quickly can I adjust the mattress to mydesired temperature?
The Mattress allows you to set up temperature between 12℃and 55°C(54 °F-131°F)-it works by heating or cooling water,which is then circulated through small, undetectable pipes within the mattress.
How often will I need to refill the water holder in the Mattress Hub?
Generally, you can expect to refill it every 2-3months.However,this can vary dependingon how often you use the heating and cooling features.Always refill with distilled,orpure water.
How long does it take the Mattress to reach my desired temperature?
The Mattress takes approx 30-45 minutes to cool or heat in normal mode,and around 30 miutes in the 'super'modes.Please note that the ambient temperature of the room will affect the heating and cooling times.We recommend powering on and pre-setting your Mattress around 1hour before going tobed.
Can I use a mattress protector over the Mattress?
You can choose any mattress protector that suits your needs and preferences.It can beplaced directly on your mattress or over your sheet.
What is the difference between NYX01/02PULS and NYX01/02PRO?
Same appearance, just different water pipe connections. NYX02PULS is connected with a CPC plug that is from US which has the pattent of no water leaking after removing the water pipe ; NYX02PRO is connected with a standard pulg, you need use a container to load the water when removing the water pipe.
Can NYX02PLUS/PRO control dual zones by a hub?
Yes, not only you can control different temperatures in two zones, but you can also turnoff either the left or right zone. But please note both zones must be in cooling or heating at the same time and can be adjusted to different temperatures. We recommend that the left and right sides of the temperature can not be set 8 ℃ difference, because the tank is next to each other, the temperature will affect each other if the difference is too large.
Is the temperature shown on the screen equal to the mattress temperature?
No, the temperature shown on the screen is the temperature of the water pipe. Generally the temperature shown on the screen is lower 8-10 ℃ than ambient temperature of the room. The water pipe is in the middle layer of the mat and the mat neutralizes some of the temperature.
