Live Large on a King Size Hullo

Weighing in at 13 lbs 12 oz, our king size pillow is a very substantial pillow. This pillow’s large size also works well as a body pillow or pregnancy pillow. We manufacture the king size pillow due to customer demand, making this is our American take on the smaller sobakawa pillows popular in Japan. Popular throughout Asia for centuries, buckwheat pillows are a proven means of attaining better, more restful sleep. Filled with thousands of tiny all-natural buckwheat hulls, they provide support for your head and neck with similar qualities to a bean bag. Soft, compressible pillow fills like down or foam can collapse under the weight of your body as you sleep. They are unable to provide adequate support which results in poor sleep posture and discomfort.

Adjustable, Firm Support

By adjusting the shape and thickness of Hullo, you create perfect support for your neck and head. This removes stress from your spine. A buckwheat pillow’s firm, yet malleable, quality supports the space beneath your neck, keeping your spine straight and allowing your neck and back muscles to completely relax. Many people are pleased to discover how something as simple as a pillow can have such a positive impact on their sleep.

Adjust the thickness and malleability of Hullo by adding or removing buckwheat hulls anytime. Hullo ships fully stuffed, so you'll have plenty of buckwheat hulls to get your pillow just how you like it.

 Cool & Dry Breathability

Traditional pillows retain body heat, making your pillow uncomfortable, particularly during the hot summer months. The lack of air flow prevents warm air from escaping your pillow’s fill. Hullo’s buckwheat hull fill allows air to move freely through your pillow, preventing uncomfortable heat build up. Sleep on the cool side of the pillow all night long without flipping.

 Organic, Natural Materials

Natural materials and quality construction set Hullo apart from most other pillows. Compare, and you'll see – From the 100% certified organic cotton twill case, to the carefully sourced and selected buckwheat hulls, we make our buckwheat pillows in the U.S.A. with the finest materials available. Our pillows are sewn with durable overlock stitching and a center lapped zipper with a secure zipper pull pocket. Our premium buckwheat hulls are grown and milled by American farmers, unlike cheap imported hulls, which are roasted. Buckwheat pillows contain no animal products for those interested in a vegan lifestyle. Conserving the land and waters on which all life depends is very important to us. We contribute 1% of our profits to The Nature Conservancy.

This pillow really is great. I don’t think there will ever be a magical, perfect pillow. But this is probably about as close as we’ll get. It’s so, so comfortable, and the coolness of it is actually mind boggling.

Customers Review King Size Hullo

Greenville, OH

Closet Full of Unloved Pillows

 I can not even count all the pillows I have tried until Hullo! I have the king size Hullo pillow and after a few nights, finally threw out my pillow of 25 years with confidence that I had finally found the perfect fit.   I have had this pillow for three months and love it. The pillow is heavier than I expected but does not slide around on my bed.   I am a side sleeper and the hulls  allow me to flip from side to side without loss of support.   I sometimes sleep with my arm under my pillow and have no alteration in comfort.  The hulls allow you to customize the height of the pillow under your neck.   They do produce a slight noise but I don’t even notice it anymore. I wake up less during the night and have had significantly less neck pain.   It is also cooler than others that I have tried. Thank you Hullo from one very grateful Registered Nurse.


The Best Pillow You Will Ever Sleep On

I am obsessed with my Hullos. When I am at home, I cannot sleep comfortably unless I have them. I definitely miss them when I traveling, and I am going to purchase a small pillow for traveling. I use them as back support and as a pillow to hug while I am sleeping. I love that they are moldable so I can customize the support of my back and neck. Ihey take some getting used to, and they are more expensive than some pillows, but well worth it.  Plus I love that they are organic and stay very clean/dust-free. I honestly can't say enough good things.  Highly recommend!!!

Love It!

I have no complaints with this pillow. While it is much more than I would normally spend on this type of an item, my sleep suffers so I thought it was worth spending the extra cash on. I also loved Hullo’s return policy as I thought it was a safe option when jumping into the buckwheat pillow game. I bought the king size pillow and it shipped quickly. I am a stomach sleeper so I took out two gallon ziploc bags of the hulls. I could probably take out a little more but I tend to just rearrange the hulls if it feels too raised. I love the customizability and that it is made to last a long time. I don’t see myself going back to a standard fill pillow.

Buckwheat Pillow FAQs

What are the advantages of buckwheat hull pillows?

Buckwheat hulls have several advantages over traditional pillow filling like foam or feathers. Most significantly, buckwheat hulls do not collapse under the weight of your head. They provide excellent support for your head and neck. The buckwheat hulls conform perfectly to the unique shape of your head and neck. This allows the weight of your head to be evenly distributed, which will prevent any undue stress on the muscles in your neck. In addition, buckwheat hulls do not conduct or reflect heat like other popular pillow filling types. They’re breathable, allowing warm humid air to quickly escape, keeping you cool all night long. Using a zippered opening, the buckwheat hull filling can be added or removed to provide the thickness you prefer. Buckwheat hulls are also an economic choice – they tend to have a much longer life span than most pillow filling types.

What size buckwheat pillow should I get?

For most people, we recommend the standard size buckwheat pillow. It’s by far the most popular size and it works with any standard bedding sets and pillow cases. We think it’s the perfect size for every-night use. Many people use the smaller size for travel and it is great for kids too. The smaller size is also closer to traditional japanese-size pillows. The king size can be just as comfortable, and works great with your king size bedding. Weighing in at around 15 pounds, the Hullo in king size is a very substantial pillow.

How long will a buckwheat pillow last?

With proper care your buckwheat pillow can last many years. Over time, the buckwheat hull filling will slowly become flattened, and lose some of their elasticity which may reduce air-circulation and loft. We offer top-quality buckwheat hulls which will extend the life of your pillow indefinitely.

Where is Hullo made?

Hullo’s current stock of buckwheat hulls were grown in Montana and North Dakota. All our buckwheat hulls are milled and air-cleaned in North Dakota. Hullo’s high-quality 12″ Dunlap zipper is made by Dunlap Zipper Company, based in Dunlap, Tennesee. Hullo’s labels are woven and printed in Colorado and woven in New York. Every Hullo is assembled in and shipped from Duluth, Minnesota. Thank you for supporting American small businesses!

What pillow case can I use with Hullo?

You can use your favorite bedding with Hullo. Standard and King size pillow cases are a standard size and available from most bedding brands. Small Hullos are a somewhat less common size, but many brands offer pillow cases for 14″ x 20″ pillows. These are commonly marketed under various names including: “travel pillow case”, “small pillow case”, or “toddler pillow case”.

Can I heat or cool a buckwheat pillow?

Cooling buckwheat pillows is possible and safe. Some people will chill their pillow in the refrigerator, freezer, or even outdoors or in an uninsulated room in cold weather. While it is feasible and safe to cool your pillow in a refrigerator or freezer, never put your buckwheat pillow in a microwave or conventional oven. It will reduce the moisture content in the hulls and is also potentially unsafe.

How do I clean a buckwheat pillow?

Hullo is designed to be used with your regular pillow cases, and therefore should not require cleaning very often. When it’s time to clean it, just unzip Hullo’s pillowcase and empty the hulls into a dry container. It is unnecessary to clean the buckwheat hull filling. Wash your pillowcase in cool water and air dry. Replace the hulls only once the pillowcase is completely dry.

Are buckwheat pillows firm or soft?

Hullo is a firm pillow. Many of us are acclimated to soft and squishy traditional pillows, so a firm pillow might sound uncomfortable. Buckwheat hulls conform to the shape of your head and neck, eliminating any pressure points, so it doesn’t feel “hard.” It will comfortably cradle your head consistently all night without collapsing like soft pillow types. It can take some getting used to , but it’s worth it!

Are buckwheat pillows noisy?

Hullo buckwheat pillow makes a gentle rustling noise when moved. Most people adjust to the sound after a few nights on their new pillow. This video attempts to demonstrate the sound  it makes.

Is Hullo treated with any flame retardant chemicals?

No, Hullo’s organic cotton twill cover and buckwheat hull fill is not treated with any flame retardants.

What happens when a buckwheat pillow gets wet?

Hulls that get slightly wet should dry out fine – putting Hullo in a sunny window might help speed up the drying process. If they get really wet, you can spread them out on some dry towels and they will dry out. If you’d prefer, we offer replacement buckwheat hulls of the finest quality to restore Hullo to like-new condition at any time.

How do I adjust the buckwheat fill?

Depending on your personal preference, you may want to adjust the amount of fill in your pillow. The amount of fill influences both the pillow’s thickness and malleability. We want to ensure you have enough fill, so our pillows ship fully-stuffed. To remove hulls, be sure your pillow is standing on its end with the zipper facing up before you open it. Unzip the cover and use a cup to carefully scoop the extra hulls into a storage bag. Once you dial in your preferred amount of fill, you can fully enjoy the benefits of your personally adjusted buckwheat pillow.

Could I be allergic to buckwheat hull pillows?

While buckwheat pillows are often described by some as being hypoallergenic, a small percentage of people could experience an allergic reaction to buckwheat flour residue which can remain after the milling process. We take extra care to purchase only buckwheat hulls that have been thoroughly air-cleaned of any leftover flour or foreign material.
