Features 8
- Cotton
- Intelligent water cooling: Luna circulates chilled water through soft silicone tubes to absorb excess body heat and stabilize your sleep temperature, staying comfortable and cozy rather than cold while preventing nighttime temperature spikes
- Twin-size pad (39in x 71in) adapts to any bed: full coverage for one sleeper on a twin, left- or right-side coverage for one sleeper on a queen or king, or upper or lower placement to cool both sleepers on a queen or king
- Flip to fit your comfort: the cushioned cotton side offers a softer sleeping surface, while the breathable mesh side maximizes airflow and body heat absorption - both sides maintain the same temperature control
- Large-capacity water tank needs refilling only about twice a month with normal nightly use, far less often than evaporative bed cooling systems that need refilling every few days
- A high-performance pump and two low-noise fans deliver strong cooling while staying quiet - lower settings run near-silent, higher settings create a gentle white noise; adjust remotely without leaving bed
- Cools your body directly instead of the whole room, using far less energy than air conditioning - many users lower their AC and let Luna regulate their temperature, cutting cooling energy use by up to 50%
- Built-in smart night features include a soft wake-up light, a customizable multi-color night lamp, and a sleep timer that adjusts cooling automatically through the night
Description
What happens if I accidentally overfill the water tank? Overfilling can cause the unit to stop working. If that happens, empty the tank and tip the unit upside down briefly to drain any excess water before refilling to the correct level. Will it ever randomly shut off during the night? Most units run reliably through the night, but a small number of customers have reported it shutting off unexpectedly (unrelated to the timer). If this happens, check the timer first, then contact support if it continues. Will the pad feel ice-cold, or just mildly cool? It's designed to sit slightly below body temperature and continuously draw heat away, not to feel ice-cold like a chilled pack. For a stronger effect, fill the tank with cold or ice water rather than room-temperature water.

5 out of 5 stars! Forget 8sleep, this costs a fraction and works so well! I got 3 already!
Color: Gray
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.

Leaks, and doesn't work well at all
Color: Gray
I have tried both plugs, and the dam thing just constantly leaks water out of the drain. Also like 4 or 5 lines in the sheet for crimpted and crushed from when it was packaged , so the only water that seems to be flowing is only near where my head is, and that spot only seems to be cooler.

Works well and also humidifies.
Color: Gray
At 184$ I think it's great. In essence this is an evaporative cooler that cools down the water. The cooled water is pumped through the pad which helps cool you down under your sheets/comforter. Yes, I can feel the tubes in the pad, but not a big deal for me with my memory foam mattress. Being an evaporative cooler the performance will be strictly tied to the room's humidity. If you live in a humid area it will not be as effective as if you live in a dry area. Performance will of course improve if you are running a conventional AC system in the room. Here in West Texas, I welcome the humidity that it adds to the room. I wished that the unit was more robust though. Brass fittings for example. It feels very flimsy. I will update in the future if it breaks. If it does, I will gladly fix.

Works ok, but there are better options if you have the money
Color: Gray
I bought this for my spouse because like me, she is a hot sleeper. I have a Chilipad cube which I love but I decided to try this out since it is about 1/3rd the price and it uses less electricity. The difference between the Dreamora Luna and the Chilipad cube is that the cube actively cools the water below room temperature where as the Luna sort of just pulls your body heat away with the moving water and cools it to room temperature with a fan. The Luna also makes the room noticeably more humid, while the cube does not. The cube just works better for keeping you cool at night. Also the water tubes for the Luna are kind of short which forced us to use the "cool" side due to the layout of the room and where we wanted to place it. The positive of the Luna is the price. It seems to be good quality, it looks good, was easy to install, and has a few extra features like a night light and timer. The noise level isnt bad at all either. Overall, it works ok but there are better options if you have the money. Its just different technology that is cheaper.

doesn't work in summer
Color: Gray
if you put ice cold water in it it works (sort of) but anything warmer than that it doesn't do anything, especially during hot summer heatwave. if you accidentally put too much water in it stops working until you empty it and tip it upside down to remove all water inside. only used it 2 nights, then got a window ac

Works great for me!
Color: Gray
Keeps me from overheating in the middle of the night, pretty impressed, it uses 4cups of water per night in a dry area of the country, currently using on a foam hybrid mattress, I have it on the padded side and unit is at end of the bed I run it on #1, beside my head was a no go for a silent sleeper. I might buy a second.

Don’t do it. They are bad

Ordered two of them and they were delivered April 30. First one died June 4th, second in June 6th. Absolute piles of garbage.

Works to stop snoring and night sweats
Color: Gray
Oh my goodness he loves it! Bought for a dude whose 36, about 330lbs, always hot and snores. When I tell you he didn't snore and was a snuggled little teddy bear the next day! I'm mad we bought the mouth guard snore thingy and the wedge pillows. Whole time he just needed to regulate his body temp better! If it doesn't work right, switch hoses and make sure to stretch the tubes all the way horizontal. He sleeps directly on it.
