It arrives full
Every pillow arrives with about a third more than most people keep, because it is easier to take some out than to wish you had more. Open the box and sleep on it the first night as-is.
Every material we use comes from a plant, a tree, or a sheep.

If you've sent more pillows back than you've kept, you're our customer.
“I have owned more pillows than I have owned houses and I have owned 12 houses.” This is by far the only pillow to use if you don’t want to wake up with sore shoulders or neck. I have replaced all the pillows in my house with this pillow.
I have compressed discs in my neck, and I have spent hundreds of dollars over the past 6 months trying to find one that will help me sleep. Every pillow I bought caused me to wake up in even more pain than the night before!! The buckwheat pillow is life-changing!! I have slept through the night and wake up with no pain!!
I was leery to try another expensive pillow without some sort of trial period after being very let down by a different company's natural fiber pillow… I don't hear anything at all with the buckwheat! It does stay fresh and cool as well, but most importantly it actually holds my head/neck up and in place. Which allows me to actually get rest instead of always adjusting.
I've been a buckwheat pillow customer for the last 7 years and I can say that Circadian has the highest standards of quality paired with incredible customer service. Very very impressed and would not hesitate to send anyone their way.
I have spent years searching for a pillow that feels supportive and comfortable all night. I have finally found it. I absolutely love the Buckwool pillow. I removed a bit of the material to get it to exactly how I want it… I rarely wake up with neck pain now.
I find myself switching between the two and loving the feel of both. I haven't woken up with a sweaty head with either and that's an amazing feeling especially in the AZ summer. The buckwheat side is a lot quieter and more comfy/soft than others I've tried in the past.
I was looking for an organic down feather alternative and the kapok-filled pillow is actually better!… It's firm enough to support my neck while being soft and moldable at the same time.
I have tried at least 10 different pillows in the last 3 years. Nothing has worked out except for this wool pillow. I have chronic neck pain which has been greatly reduced. I am very happy with my new pillow.
I have pretty bad chemical sensitivity (housebound most of the time)… I try to only buy totally safe, non-toxic products. I found this pillow to be very safe and non-toxic, and the packaging was fragrance free which is always a huge plus.
I ordered this pillow to replace my very old (but beloved) down pillow and I'm so glad I did. It is heavenly!… I advise you to heed the recommendation given by the quiz. I ordered cotton initially despite the quiz giving me kapok as a result… the quiz was right.
The quality craftsmanship and materials is evident… when I asked if extra stuffing were available for the second one I'm using as a knee pillow, they not only pointed me to the right place on their site, but also created a new, smaller 1-lb. refill size based on my request.
I requested a bit more filling for my two pillows, they seemed a bit flat for me, and the customer service was amazing. I received a hefty bag of extra organic cotton filling. After trying these pillows, you'll never go back to synthetic.
This is the best pillow I've had. It gives the right support around the head and neck. It doesn't sink or move and stays cool through the night. Also, it's easy to make small adjustments to make it fit perfectly.

Duvets
The duvets are filled and sewn in the same New Jersey workshop as the pillows, and carry the same Global Organic Textile Standard (GOTS) certification.
From box to bed
Every pillow arrives with about a third more than most people keep, because it is easier to take some out than to wish you had more. Open the box and sleep on it the first night as-is.
Use the zipper to remove fill a little at a time until the height feels right. Most people take out a handful. Keep what you remove in case you want it back.
Give it a real shot. If it’s not right after 60 nights, we’ll take care of you. No restocking fees, no hassle.
