DREAMORA Luna – Water-Cooled Bed Cooling System – Elegant & Compact Bed Cooler for Hot Sleepers, Deep, Restorative Sleep – Dual-Sided Cooling Mattress Pad & Precise Temperature Control

5 out of 5 stars! Forget 8sleep, this costs a fraction and works so well! I got 3 already!
I backed this on Kickstarter and got 2 units for my wife and me. They worked so well that I later bought 1 more for my kid on Amazon. Now we have 3 in the house, all running perfectly, zero issues.This is NOT an ice-cold pad. It sits slightly below your body temperature and continuously absorbs your body heat through the night.Don’t expect instant magic. It takes a bit to adjust, but once you do, it works great.Tubes: you feel them with your hands, but once you lie down your weight spreads out and you don’t notice them.Noise: soft white noise, not disturbing.Humidity: none. Used for 3 months, refill only needed once, even in a slightly humid environment.Setup: super easy.Emptying: use the included short tube, bring it to the sink, drain from the bottom. No water spilling anywhere.Leaking: none for us.I used to wake up once a twice a night from tossing and turning, this product has solved this which is invaluable to me.If you expect a freezing mattress, this isn’t it. If you want consistent, comfortable sleep without overheating, this absolutely delivers.I also made thermal images and you can see how the tubes cool the pad down. You might not instantly feel it by simply laying on the pad for a short while, but you can see it works on the image’s.

Received used product
When I received this product it looked to be used. Still had water in the basin. I plugged it in and filled with water and nothing happened. The lights came on for a brief moment and then shut off. I would not recommend

Good product, but could be better
Husband loves this but the light won’t work anymore

Der Sommer kann kommen! Gerade angeschlossen und ausprobiert. Matratze wird spürbar kühler und dank der Ventilatoren der Raum auch etwas. Ich denke, die 200 Euro sind sehr gut investiert.

This is going to be one of my longer, maybe my longest reviews as It’s a pretty simply designed product, but a bit of a complicated, the TL;DR & put simply, is that this doesn’t actively cool you, it passively cools you by taking the heat that would make you sweat, and making the machine do the sweating instead. The system does not refrigerate the water in any way to cool it down, so limit your expectations, but It works well for me so far.So, to understand how this product works you need to have a basic understanding of heat transfer, This works the same way you sweating does in principle. The water gets heated by your body temp, then gets pumped into a filter which has fans blowing on it that remove the heat by evaporating the warmer water, this is a passive method, not an active one so you won’t be getting significant changes in temperature, but instead regulate the heat that’s generated by your body.All that to say, is that it basically stops you from sweating & getting hot by making the machine do it instead.Now that the explanation is out of the way, hopefully you understand the concept, and what this product does, the benefits are that I did notice a better overall sleep, I have had issues with overheating where I would wake up many times during the night, toss & turn, get sweaty & generally speaking not getting good sleep.This has almost entirely alleviated that issue, I still wake up now & again, however I want to point out that I also got a pretty rough cold as soon as I started testing this, so I would likely attribute waking up to the cold, as I’m waking up with a lot more energy than I was before.Now the issues, Principally the humidity. Due to this evaporating water or “sweating” so to speak, the humidity in the room rapidly increases, I measured as much as a +35% increase from 40% to 75% in one night, long term this is an issue as if you don’t deal with the humidity, it can cause mold & unwanted condensation, but most importantly there will be nowhere for the water to go, so it will stop “cooling” & just have a constant temperature.That said, paired with a dehumidifier, hypothetically the cooling potential of this is very solid, and you won’t have any humidity issues.Another issue, is that this is very temperature dependent on cooling. the average human body temp is 36-37°C, if your room is in the low 20’s it will work fine, but as the ambient temperature rises closer to your body temp, the less impact the system will have.Additionally, the infrared remote seems to use a spectrum that several other products in my room uses which is really annoying, It messes with my RGB strips & my essential oil diffuser when I try to use the remote to control the settings.Issues aside, assembly was quite straight forward, just pu the anti-slip pads on the feet, put the feet on the machine, Put the clamps on the tubes BEFORE you push the tubes over the outlet/inlet for the pump, fill up the tank slowly, don’t rush it for reasons seen in my final notes. Then lastly turn it on & wait for the air to bleed and water to fill the pipes, then you’re good to go.As for my final notes,I want to point out, I can quite notably feel the tubing when I lay on it, and this will be a problem regardless if you’re using the “comfort” or the “cooling” side, this may be a do not pass go for many of you, but I don’t find it to be a problem, as I still find my bed to be comfortable while using this on the cooling side, and once i fall asleep I can’t even tell it’s there.As for “Feeling” the cooling, It does have a cool sensation with the parts of the tube where cold water flows in, but by the time it’s picked up your body heat, you don’t feel it anymore, this is proof that it’s working as intended.I did some research & this product is also relatively new, & was a Kickstarter project that started in November 2025, & is only recently shipping out products. There seems to be some issues with units dying from various causes, in many complaints I’ve seen it’s due to overfilling the water when trying to fill up the tank, so be extra careful when filling.Overall, I’m satisfied. Down the road, I would be willing to buy another product like this once this one quits, I recommend to use the minimum cooling setting on 4 when actually sleeping, but 9 if you just want to have a “cool” effect while you’re laying in bed.

The DREAMORA Luna water-cooled bed cooling system is a really cool idea on paper, but the actual performance of the unit leaves much to be desired. I think with future improvements, the cooling system could reach a point where it will meaningfully cool your mattress or whichever place during a hot summer, but as tested today it really wasn’t able to do a whole lot.Assembly is pretty simple out of the box, install the four legs by plugging them in and adding the anti-slip base, hook up the tubes and push them in, slide the clamp over and fill from the top, plug in and good to go. All this took about 15 minutes and once powered on, the system can go from 1-9 stage settings, but this really only adjusts the fan speed and didn’t significantly impact the cooling performance. After a few hours, I still didn’t feel too much cooling on the pad, and at the maximum setting the fan does get a bit loud, between 2-4 I think it produces a pretty steady and soothing noise to fall asleep to, and the RGB light can be neat if you like that kind of thing and it doubles as a night light.The main issue is that I didn’t really feel any noticeable difference in temperatures, even after cranking the fans to the max speed. I think the main idea is that the water in the tubes of the pad soaks up your body heat, then it loops back into the cooling unit with the fan and then gets cooled and circulated back. This sounds great in my head, but again it didn’t really offer me a whole lot of actual cooler temperatures.
