For the most luxurious, plush feel, these mattress encasements pair 4-way stretch organic cotton with a generous lining of ultra-soft organic wool. Breathable, thermoregulating, and moisture-wicking, these natural fibres help keep you and your mattress fresh and clean.
Easily unzip this encasement to access your adaptable organic latex layers inside.

Frequently asked questions
Questions about our Kakun Twelve Organic Mattress.
What does the Twelve feel like?
What does the Twelve feel like?
The Twelve opens with plush organic latex at the surface, giving immediate cushioning and pressure relief around the shoulders and hips. Beneath that, the comfort, support, and base layers are chosen to suit you, so the overall feel can range from soft and enveloping to firm and supportive depending on the combination you select.
What is the 2-inch soft top layer and what does it do?
What is the 2-inch soft top layer and what does it do?
The 2-inch soft top layer is a layer of plush organic latex that sits inside the top of the mattress, just beneath the cover. It provides immediate cushioning and exceptional pressure relief, particularly around the shoulders and hips. Like the other layers, it can be removed and flipped to increase longevity of the mattress.
How does the four-layer system work?
How does the four-layer system work?
The Twelve includes a 2-inch soft top layer, offered in one feel only, a customizable three-inch comfort layer (Soft or Medium), a customizable three-inch support layer (Soft, Medium, or Firm), and a customizable four-inch base layer (Medium or Firm). All four layers can be removed and flipped, and the three lower layers can be configured independently on each side of the mattress.
How often should I rotate or flip the layers?
How often should I rotate or flip the layers?
We recommend rotating and flipping the layers every four months, this prevents body impressions from forming and increases the longevity of your mattress.
Can the layers be adjusted or replaced down the road?
Can the layers be adjusted or replaced down the road?
Yes. Because no adhesives or glues are used anywhere in the construction, the three customizable layers can be rearranged, flipped, rotated, or individually replaced as your sleep needs change. The mattress adapts with you over time, which is part of what makes it such a long-term investment.

We purchased this mattress after my husband sustained an injury and it became obvious that our old, high end mattress was not helping. We had this new mattress custom layered to accommodate us individually and are very happy with it.
The mattress is great! The main reason being my wife and I have different desires in softness. I like firm she likes softer. With the Kakun you get what you on your side of the bed. Plus, if you want to adjust later you can do it yourself or even but another layer at a different hardness; you don't have to change the whole mattress.👍
All body parts are thoroughly happy on this mattress
We are delighted with our mattress. It’s first of all absolutely gorgeous in every way! And just to feel the mattress cover holding in the different layers of carefully curated and arranged densities of organic latex. We had the best time with Sharlene and Chris decided on the layers of each side for our specific comfort and support needs. I love that the mattress is in layers that can be flipped and adjusted for longevity and ultimate comfort. And knowing that it’s all organic and very well made gives us a beautiful sense of peace. It’s a joy to sleep on. Thank you kakun.
Don't hesitate. This mattress is worth its weight in gold.
Well designed, comfortable mattress system. Big change, but best choice for us.
I love this mattress. We had tried a couple other mattress from different stores and weren't happy with them. I need a softer mattress and my husband needs a firmer mattress and the fact that we could adjust the firmness for each of us was a game changer. Have had a great sleep since buying this mattress about 8 months ago.
It was a unique experience to "build" my own mattress to meet my specific comfort needs. Without the topper, sleeping on this mattress feels like you are floating. The topper takes the mattress to another level of comfort. Contrary to information on the internet, these latex mattresses do not smell like rubber. They have a unique light scent which is such a delight given that I wish a gas mask was provided when I got my old mattress.
Hello, and thank you for the 5-star review and for sharing your experience! Every sleeper has unique needs, and our Kakun mattresses are designed to adapt by rearranging or swapping out layers to match your evolving preferences over time. We're glad you're enjoying the extra comfort of the Eco Wool Topper 😴 and the fresh, natural scent of the latex—no harsh odors here! Reviews like yours help others improve their sleep, so thanks again for sharing. Sleep well ... The Resthouse Team
I am a restless sleeper and, before this bed, most nights saw me waking frequently. I also sleep on my stomach a lot. We've had this mattress over a month now and I am waking much less frequently and, when I do wake, get back to sleep more quickly than before. We also really appreciate having different firmness on each side.
Hi Virginia, we really appreciate you taking the time to send in a review of your new Kakun Twelve Mattress and the White Glove Service. Every body is different, so it stands to reason that we have different needs from a mattress ... that's the beauty of being able to customize your side exactly how you like it. We are so happy that you and your partner are finding the mattress comfortable and you're waking less frequently during the night! Please keep in touch and let us know if there's anything we can help you with. Sweet dreams ... Resthouse 😴
Thoroughly enjoyable purchase experience and product. Great staff that were knowledgeable and low-pressure, allowing us time to make the right decision. Our sleep has improved and we can also say that "everything is better on a Kakun" ;-)
Product itself has provided us with extremely COMFORTING sleeps. We now sleep longer and deeper. Seriously. So thrilled to have made this purchase decision!!!
Great bed. Customer service also good with bed set up. Thanks
I have never slept as well as I have since purchasing the Kakun Twelve Mattress. I was able to customize the layers of the mattress to fit my personal comfort needs of a firm base, with a soft top layer. (For insane softness, I recommend also getting a wool topper-luxurious). I no longer wake up with any body pain, and am having some of the best sleep of my life on this mattress. Well worth the investment.
Hello Starr,
Thank you so very much for sharing this review with us and for your support. We are so glad that your mattress is offering you such amazing sleep.
Sweet dreams,
Resthouse
Product is comfortable, however salesperson and store follow-up were very poor. Roland, who made the base of the bed was excellent, prompt and easily contacted. However, when I tried to contact store for information I never received a call back either time.
