Shikibuton Buyer's Guide: The Traditional Japanese Futon Mattress
This buyer's guide to shikibutons includes not just buying options for the shiki futon mattress and accessories, but also information about how to care for a shikibuton so it will last many years.
What Is a Shikibuton?
Traditional shikibutons are slim, rectangular, cotton-stuffed sleeping cushions that are more versatile than the thicker futons most people know. In Japan, these simple mattresses are part of a style of minimalist living that goes back centuries. According to Handmade Style: Japan, a shikibuton is usually laid out on the floor atop a straw mat called a tatami and covered with a goose feather duvet and pillows. When not being slept on or used as a sitting cushion, they are folded up and stored in cupboards.
What Is a Shiki Futon Made of?
Shiki futons are eco-friendly and made without synthetic fibers (foam) or innersprings. Stuffed with 100% cotton—if not always organic cotton—shikibutons are considered "green" by many. The cover is usually also 100% cotton, in a durable cotton duck weave, and often comes with a zipper to make re-upholstering easy.
How Much Do Shiki Butons Cost?
They are not exactly cheap, but starting at a couple of hundred U.S. dollars for a twin size as of this writing, they range from reasonably inexpensive to quite expensive. Shikibutons that come with a removable cover cost more than those that don't. Those stuffed with wool or latex layers in addition to the cotton batting tend to be more expensive than the simple 100% cotton ones. Organic cotton 3" futons will cost more than those made of standard cotton, sometimes as much as double the price.
What is the Difference Between Shikibutons and Futons?
Shikibutons are the real traditional Japanese futons. Sometimes spelled "shiki buton" or "shiki futon," these cotton-filled cushions are thinner than American-style futons, about 3" thick, and thin enough to be rolled and tucked out of the way when not in use. The 4" ones can be folded in thirds and stored.
The standard 6" or 8" futons sold in most stores, on the other hand, are too thick to be rolled, weigh more, and tend to be a permanent part of the furniture - and thus take up more floor space. They are usually made with synthetic foam and/or innersprings, much like a regular mattress.
If you live in a small, cramped area, like the flexibility offered by minimalist living, or are just trying to create an open-space feel inside the home, a shikibuton - or two of them piled on top of each other - is the ideal choice for a primary bed or guest bed.
Pros & Cons of Shikibutons
- The mattress easy to store - just roll it up and put it away.
- Relatively lightweight and extremely portable, a shikibuton is easier to lift and move than a futon or traditional mattress. A twin size might weigh about 25 lbs.
- There's no off-gassing, as these slim futons are made of natural materials.
- Shiki futons make good guest beds as well as sitting cushions.
- If well cared for, they last a long time and are very economical.
- Shikibutons are hard to find - they're not sold at most futon stores.
- They need regular turning and rotating to prevent moisture-absorption.
- Some sleepers may need two layers of shikibuton to be comfortable.
- Not everyone finds the firm cushioning provided by cotton padding comfortable.
- If you are over 6 feet tall and thinking of getting a twin or full size, you'd need a queen size instead, or custom order an extra-long shikibuton instead of the standard length (the length and width are usually the same as those of conventional mattresses - e.g., twin size is 75" by 39", full size is 75" by 54, and queen size is 80" x 60".)
How to Care for a Shikibuton
Shikibutons can last a long time, many years, in fact, if treated with tender loving care. Because cotton fibers tend to get saturated with moisture and we lose up to a pint of water from our bodies as we sleep, these special mattresses need some special care to keep them dry and aerated so they don't clump or grow mold.
Protect Your Shikibuton from Moisture and Keep it From Growing Mold and Mildew
- Lay the shikibuton(s) on a breathable surface, such as a tatami mat or platform bed.
- Don't let the shikibuton sit in one place day after day. To keep it dry, flip it every week for the first couple of months and then once monthly. Or in the daytime, simply roll it up (or fold it up in thirds for the 4" "tri fold" futon mattress) and store it away.
- Sun it twice a year to bring the cotton "back to life" - and also to keep dust mites and mildew spores from becoming a problem. Lay it out in the sunlight on a sunny day over a bunch of chairs or on a table for a few hours on each side.
- Use a natural cotton shikibuton protective cover or pad to protect your shiki buton.
Keep the Shikibuton from Forming Permanent Dips
- All-cotton shikibutons tend to form dips where the body lies. If you lie in the same place every night, turn the shikibuton around (i.e., head to foot) every few days. Or "fluff" the shikibuton by hanging it up and beating it with a tennis racket.
- Fold the shikifuton in thirds during the daytime to help stretch the fibers you were just compacting while you were sleeping on them.
- If it has a protective cover, follow the cleaning instructions for the shikibuton cover.
- Spot clean any organic stains on the futon with a mixture of water and detergent. Then saturate the area with rubbing alcohol to help dry and sanitize the area.
Shikibuton Frame or Tatami Mat?
Traditionally, a Japanese futon is laid out on a tatami mat made of straw instead of housed in a frame. Check the dimensions of the shikibuton you buy and get one or two tatami mats to cover those dimensions.
I have not tried one of the platform beds with slats, which some sleepers uses as a frame, but I suspect they may work better with two layers of shiki futons than with just one.
Types of Shikibuton Arrangements: One Layer or Two?
Shikibutons are futons for the minimalist. But they can be paired and set, one on top of the other, to mimic the cushioning of a regular Western cotton futon.
If you need serious cushioning more like a traditional mattress, you'd do best to find a local shikibuton store that makes latex and cotton or wool and cotton shikibutons.

Why I Sleep on a Japanese Shikibuton Mattress
In our search for minimalist bedding, we recently bought a shikibuton from a local natural beds supplier, and we love it. Actually, we bought two twin-size shikibutons and put them together to make a king size. After sleeping on too-soft beds and too-hard floors, and mattresses that grew mold, and other sundry issues, we decided the benefits of minimalist living outweighed the disadvantages of a traditional (for the West) bed system with box spring and thick mattress. We've had ours for about a month now, and think they're great. My husband is going to build a permanent bed frame for them.
I'm surprised we're both so happy with our shiki futons, because I always thought I needed a soft, plush mattress for my back. But it turns out I find I have less back pain with the firm cushioning provided by our shikibuton pair.
Note that out of the package, these thin futons can arrive squished and so don't spread out to their full size for several days. Some of them take up to two weeks for the futon to reach their full length after being vacuum-packed.
We bought two 3" shikibutons and we will probably get another layer when the budget permits. Right now, we're sleeping on only a single layer, and I'm sleeping on a feather mattress topper too for added cushioning for side sleeping. The store where we bought our shikibuton, Soaring Heart, says that two layers can provide as much cushioning as a single futon - but with a lot more versatility. And I can see why.
Update April 8, 2013: I just want to update everyone. We got our shikibutons around the time I wrote this article, almost three years ago. Unfortunately, we failed to maintain them. We didn't keep them on a tatami mat but put them directly on the floor. We also failed to roll them up every night...but still, we were very sad when they got musty and we had to discard them. The moral of the story is...I highly encourage you to place your shikibuton on a frame or a tatami mat and to air it out as much as possible. Also be sure to read the section in this article on caring for your shikibuton...I did not take my own advice and now I know what happens!
What are we doing now? Well, believe it or not, we've rigged an unconventional solution. We're sleeping on layers upon layers of cotton batting. Yes, the stuff used to fill quilts. It feels almost the same - wonderfully firm - but what's more, it's washable-bleachable and totally customizable in size. We from Amazon. But it's hard to roll and unroll without kinking it, so it's not ideal. But better than foam mattresses, that's for sure! got ours

Questions & Answers
Is a 100% wool-filled Shikifuton better than a cotton-filled Shikifuton? Would it last longer and prevent mold better? Will it be less likely to compact?
My guess is a 100% wool-filled Shikifuton would last longer and prevent mold better and compact less. But it has the disadvantage of not being washable and of being allergenic for some. Beds in general, I think, are made to be temporary, because the most challenging part is keeping them clean. It's only in modern times that we keep them for years, because we have access to technology that keeps them supportive for longer, yet the challenge remains to keep them fresh.Helpful 14
