The 2am problem

Your doona traps the heat. The air con can't reach it.

You fall asleep fine, then wake up hot, sticky and kicking the covers off. Throw them off and you're cold an hour later. The problem isn't the room. It's the pocket of warm, humid air sealed under your sheets.

  • Waking up hot and sweaty at 2am
  • Thermostat battles with your partner
  • Running the air con all night (and paying for it)

How Moonvale works

Cool air goes where you actually sleep.

Moonvale sends a gentle stream of air under your sheets, flushing out trapped heat and humidity so you stay comfortable all night, without chilling the whole room.

  1. 1

    Slide

    Slide the flat base under your mattress. It stays put, with no tools and no clamps.

  2. 2

    Tuck

    Raise the stand to your bed height and tuck the nozzle just under your sheet or doona.

  3. 3

    Sleep cool

    Pick one of 5 speeds and set the timer from the remote. Then roll over and sleep.

Keeping it

This one's staying by the bed.

Bedtime disagreements

We used to spend ages folding back bits of doona and then unfolding them. I can keep my side covered with some airflow now. It's not a big dramatic change, but it's made settling into bed less of a production.

Charging routine

I plug it in while I'm getting ready for work. Remembering to charge it hasn't been a drama for me.

Evening comfort

Bed feels less close in the evenings.

Not freezing

It's the feeling of air moving that I enjoy. Wasn't looking for an icy bed, just something less stuffy.

F
Frank Moretti
Better than expected

Wasn't sure air under the sheets would feel any different. It does to me, in a good way.

Familiar charger

USB-C got my attention because I already use it for other things. The under-sheet airflow is what keeps me using this.

Comfort without a cold face

I like moving air but don't enjoy a fan blowing towards my face. Directing it beneath the covers suits me much better. Had to find the right arrangement with our sheet, then it was a very pleasant addition.

Warm after work

I often get home from work feeling warm and want to relax without flinging all the bedding away. A gentle setting under the sheet suits that moment really well. Glad it has more than one speed to choose from.

USB-C suits me

One less odd charging cable to keep track of.

Gavin Price
Simple comfort

Fan speeds are useful. Some evenings I want more movement, other evenings just a little is enough.

Bed making

Needs a bit of attention when I make the bed, but that's fine. The evening comfort is worth it.

B

Fairly simple

Had to shuffle the bedding about first. Once I'd worked that out, it was a fairly simple thing to enjoy.

Cosy without feeling quite so bundled up.

No cold face

Love that the breeze isn't in my face.

Useful beside air con

We still use the air con when it's stinking hot. I like this for the air trapped under the quilt.

No furniture shuffle

The power points in our rental seem to be everywhere except where you need them. Cordless use makes this easier for us. I can charge it away from the bed and put it where the airflow feels best.

Taking it along

Handy to bring into the other bedroom when family stay over. I like not having a lead across the doorway.

Enjoying the gentle air beneath my quilt.

My side of the bed

My husband can be under two layers while I'm lying there wondering how he's comfortable. We tried separate covers, which helped, and then this for my side. I like that I can choose a gentler breeze without deciding what the whole room should feel like. It took some fiddling to arrange everything so we were both happy. Now it's simply part of how we set up the bed, and I'm pleased we tried it.

Quite pleased with it, thank you.

Useful option

Nice having a choice of fan speeds.

Actually using it

I've tried a few comfort gadgets that end up ignored. This one gets used because I like the feeling straight away when I get under the sheet. Nothing to rave on about, just a useful part of winding down.

Gentle breeze

That little breeze under the sheet feels so nice.

Got 2 of these, one for me and one for the missus. We both sleep pretty hot so thought we’d give them a go. Actually surprised how much of a difference they make… We barely have the aircon on at night anymore. Very happy with them 👍

L
Linda

Absolutely love this!! I’m one of those people who NEEDS a quilt to sleep but I get so hot in summer 😂 This blows cool air straight under the covers and honestly makes such a difference. I’m barely using the aircon now too. Wish I found it sooner! 😍

FAQ

Questions, answered.

Something else? Email hi@moonvale.com.au

Will it wake my partner?

On low it's whisper-quiet, and the air stays under your side of the covers, so your partner can stay cosy.

How long does the battery last?

Up to 22 hours on the lowest speed and around 5 hours on max, from a 10,000 mAh battery. It recharges in about 3.5 hours.

Does it work with a heavy doona?

Yes. The nozzle sits just under your sheet or doona and lifts it slightly so air can move through the bed.

Will it fit my bed?

The flat base slides under most mattresses, and the telescopic stand adjusts from 22 to 53 cm to suit most bed heights.

Is it cheaper to run than air con?

Much cheaper. It's a small, low-power rechargeable fan, so a night's cooling costs cents rather than dollars.

How fast is delivery?

We ship from Australia with free delivery, usually within 5–9 business days.

What if I don't love it?

Try it for 30 nights. If it's not for you, send it back for a refund. Every Moonvale is also covered by a 12-month warranty.

Tonight could be the coolest night's sleep you've had all summer.
