Interesting. Living in Japan there is still a strong culture to try to avoid using air conditioning at night (in particular among the elderly), so there is a whole market for both staying warm in bed during winter and cool in bed during the hot and humid summers. My own family has primarily been using mattress protectors that conduct heat more efficiently [1], towel blankets (タオルケット) [2], and gel pads than are stored in the fridge and then put under the pillow cover just before you go to sleep. There are plenty more on the market, but I have solely by using the conducting mattress protectors been able to sleep with the air conditioning several degrees higher than I would have been able to in the past.

It is both confusing and fascinating how some companies manage to put out a product with a subscription, the existence of which defies logic and consumer expectation, and yet they manage to find a group of people who tolerate it.
I was just about to buy almost this exact setup! Excellent to see it's effective. I thought I was mad looking into fish tank coolers. I was thinking though skipping the evaporative cooler and going with a compressor model. Quite a bit more expensive but I think it'll be more effective in the humid North East.
I have realized over the years that I need to be seriously cold to sleep well. My health watch always registers a great sleep and recharged "body battery" when I've been almost shivering all night. My partner likes to joke that my body needs "suffering to get fully rested".
These days, I only ever have nightmares when I'm too hot. It's a challenge to stay cool enough to not get them.
It's an amazing product, it helps keep me cool, and is nice and firm, which I need to have a restful sleep without back pain. By far my favorite mattress I've ever used.
The Airweave has reduced my hot nights significantly, and I'm thinking if I can put a cool pad underneath it, I'll be set!
I'm going to have to try this DIY project for sure now!
You could put a small compressor outside and connect a well-insulated hose to pump the refrigerant inside, just like a split system air conditioner. Then the noise in your bedroom will be no worse than the occasional hum of a fridge in the other room.
As someone who lives in a humid climate, I wouldn't even think of using an evaporative cooler anywhere in my home, for any purpose, period. It's either compressors or nothing.
Your bed needs to be breathable. That's the single most important thing. A cool bed without proper ventilation will attract condensation and mold, and make you feel damp.
A good spring mattress sitting on top of slats will never get uncomfortably hot or cold in any particular spot, because air moves freely in and out, powered by your own body movements.
The mattress should also be as firm as you can tolerate. A firm mattress leaves breathable space between some parts of your body and the surface of the bed, instead of allowing your body to sink into the foam and become insulated on all sides. Again, airflow is key. Regardless of what heating or cooling solution you have, airflow will multiply its effect.
A cooler mattress is better to sleep on? That sounds like the opposite of my experience, unless the weather is uncomfortably warm and there’s no air con.
A lot of research seems to suggest that cold (something like 62F-68F) is indeed better for sleep. It makes sense if you think about it "evolutionarily" or whatever. Basically, your body feels warmth and it assumes the sun is what's heating you up, so suppresses sleep hormones and promotes wakefulness.
Anecdotally seems true for me, but I also have poor circulation to my extremities so I just suffer one way or the other.
In my experience, I might like a cool bed if I was hot in the evening (say, I was physically active). Otherwise, I prefer a cool room with a nice blanket.
