Question: Does this pillow stay pretty cool at night or does it get warm while you sleep.
Document: We've used buckwheat pillows for years and love them. They conform to your head and neck like a an ergonomic foam pillow, but still "breath". This means that your head will stay cool all night long. Until we purchased this one, we never found one at a reasonable price that was actually a full size pillow. They tend to run very small and relatively flat (I guess buckwheat must be kind of expensive to use as a filler).
Love, love, love this pillow. I've never used a buckwheat pillow before and found it very easy to get used to - one night! I have issues sleeping and this pillow keeps my head cool and limits how much I toss and turn. It improved my quality of sleep immediately. I've since bought one for my husband. Love, love, love this pillow!
I sleep soooo hot at night. Even when it's 10 degrees and I don't use the heater, I still wake up drenched in sweat, especially my head. While I can't say my head stays really cool on this pillow, I can say that it does not get hot either! It does seem to keep the heat transferred away. Have had this pillow for about 3 weeks and my husband has been using it to and loves it. I am ordering him one today!
Dont be turned off by this tho. Buy a cheap  pillowcase and cover with a second pillow case  when changing the linens. *  Your friendly UPS / FedEx driver will curse you for ordering these puppies. They weigh a ton  but are worth it.Give it a week. You'll be surprised at how good your neck and back feel. They stay cool and make a little crunchy noise when you turn but its like the  buckwheat is singing you back to sleep. *  Worth the Money. Saves on chiropractic bills
The pillow is slightly heavy, but I think this is an advantage as it help it to stay in place if you move alot during the night. I use a CPAP machine and the way the hulls can be redistributed help me sleep on my side, making a little channel for the CPAP mask and hose, and I can sleep without breaking the seal. Stop searching and buy this fabulous pillow from Beans72!
It was solid but i patted down a nice little gap for my head and I found I'd sleep pretty nicely throughout the night.5. Buckwheat pillows are usually ridiculously small. Japanese size or not, they are just stupid. I need a queen size pillow or it throws off the feng shui of my new room, not to mention where do you find a case for them?? Nowhere.
I bought it the day it came I saw this was probably going to be an excellent pillow it was heavy and did not give much. The second day I woke up with this pillow the neck pain and muscle spasms basically just vanished, I was shocked. I love this pillow. I have used it every night for the past 2 months and still love it. I fall asleep faster stay asleep most of the night still wake up on occasion but that's just me. I sleep strictly on my side.
Buckwheat pillows apparently doesn't attract dust mites because there are no nutritional value for the dust mites, however, some studies have shown that buckwheat hulls from other regions outside the US can contain dust mites. The pillow stays cool throughout the night and you'll never have a warm pillow because the buckwheat hulls always circulate air. I have not tried a Temperpedic pillow before so I cannot give you a comparison, but it is definitely better than a down feather or cotton pillow for sure.
Does not stay cool, now on the guest bed
Always comfortable all night long. It stays cool and form fitted.It does take some adjustment to get accustomed to the weight. Heavier than I had anticipated.
