A yoga studio orders 200 floor cushions. They photograph beautifully on day one. Six weeks later half of them sit flat, and the owner is asking for a refund. The cushions were not badly made. They were specified for the wrong job.
That is the quiet failure mode in this category. Buyers order by look and by unit price, then discover that a floor cushion is a load-bearing product. It carries a person’s full weight for 30 to 90 minutes at a time, on a hard floor, day after day. Comfort on the first sit is easy. Comfort on the two-hundredth sit is engineering, and engineering is what you are actually buying.
This guide is written for importers, retailers and hospitality buyers building a tatami-style floor cushion programme. It covers what “tatami” means on a purchase order, how the four common core materials behave over time, why thickness on its own is a poor specification, what makes a cover genuinely washable rather than nominally washable, and which build suits a yoga studio versus a homestay versus a Japanese restaurant.
If you want the wider context on how we structure these programmes, start with our floor cushions in bulk buyer guide, then come back here for the specification detail.
What “tatami” actually means when you place an order
In Japanese building practice, tatami is a construction, not a material. A tatami mat is a rice-straw or wood-chip core wrapped in a woven rush surface mat and bound with a cloth edge. What Western buyers call a “tatami cushion” is usually a much simpler object: a woven natural-fibre shell filled with something soft, sized for one person to sit on.
That gap matters, because it means the word on your purchase order does not tell a factory anything. “Tatami floor cushion” could mean a 5 cm rush mat that folds away, or a 12 cm foam block in a linen cover. Those two products have nothing in common except the keyword, and quoting them against each other is how buyers end up comparing prices that were never comparable.
So we ask three questions before we quote anything. What is the core? How thick is it, measured under load or at rest? And does the cover come off?
The three-layer build
Almost every cushion in this range is three layers, and problems almost always trace back to one of them.
The surface. The woven face — rush, corn husk, seagrass, cotton rope or linen. This is the layer that gets photographed and the layer the customer touches. It takes the abrasion, the spills and the sun.
The core. What holds you up. Sponge, cotton wadding, shredded fibre, or in the traditional mat, compressed straw. The core determines whether the cushion is still comfortable after a season.
The cover and closure. The zip, the seams, the inner liner. In our experience this is the layer that generates the most warranty claims, and the one buyers specify in the least detail.
Core materials: four options, four different products
Here is the comparison we walk buyers through. Read it as “what happens after three months of daily use”, not “what does it feel like in the showroom”.
| Core | Sit feel | How it ages | Weight | Best fit |
|---|---|---|---|---|
| Rush (igusa) mat over straw or board | Firm, flat, cool | Darkens evenly, stays flat for years | Heavy | Traditional interiors, tea rooms, Japanese restaurants |
| Corn husk braid | Firm with give, textured | Softens slightly, holds loft well | Medium | Retail home decor, farmhouse and coastal ranges |
| Sponge / foam block | Soft then supportive | Loses rebound after roughly 6 to 12 months of daily commercial use | Light | Yoga, meditation, kids’ rooms, homestays |
| Cotton rope / braided cotton | Dense, springy, moulds to the body | Slow to flatten, washable as a unit | Medium-heavy | Boutique retail, studios, photo-led brands |
Rush (igusa)
Rush is the material people mean when they say tatami. It is a hollow-stem marsh grass, woven tight and flat, with a faint dry-grass smell when new that most buyers find pleasant and that fades within a few weeks. It is firm. Sitting on a rush cushion is closer to sitting on a low platform than on a pillow, which is exactly right for floor dining and exactly wrong for a 60-minute meditation session.
Rush also does something no other fibre in our range does: it regulates humidity. The hollow structure absorbs moisture when the air is damp and releases it when the air is dry. In a humid dining room that is a real advantage. In a wet climate with poor ventilation it means you must let the cushion dry out, or you will get mildew on the underside.
The trade-off is that rush is not washable. You wipe it, you air it, and you do not submerge it. For any buyer whose end customer expects to throw the cushion in a machine, rush is the wrong answer, and it is better to say so at quoting time than at delivery.
Corn husk
Corn husk is the most underrated fibre in the range. It braids beautifully, it takes dye unevenly in a way that reads as handmade rather than defective, and it sits between rush and sponge on the firmness scale — enough give to be comfortable for an hour, enough structure that you do not sink to the floor.
It is also the most forgiving in production. Corn husk tolerates compression during shipping and recovers with a shake, which matters for e-commerce sellers whose cushions arrive vacuum-packed or folded. Buyers moving volume through online channels should look hard at this material before anything else.
Sponge
Sponge is the cheapest way to get a thick cushion and the fastest way to get a complaint. Not because sponge is bad — it is the right core for yoga and meditation, where the sit has to be soft — but because density is invisible, and it is the first thing an unscrupulous quote cuts.
A low-density sponge cushion feels identical to a high-density one on the first sit. After 200 sessions the cheap one has lost 20 to 30 percent of its thickness and the customer is sitting on the floor. For a home decor retailer whose product gets used weekly, that is acceptable. For a studio using it daily, it is not.
Specify density, not just thickness. “8 cm sponge” is not a specification. “8 cm, 25 kg/m³ high-resilience foam” is.
Cotton rope
Braided or crocheted cotton rope is the premium end of the category. It is dense, it holds shape, it is soft without being squishy, and it survives a washing machine. It is also labour-intensive — a mandala cushion is coiled and stitched by hand, which puts it in a different price bracket entirely.
The reason retailers still buy it is that it photographs exceptionally well and it does not need a cover to look finished. For a brand whose entire channel is visual, that is worth the unit cost. Our crochet mandala cotton rope floor cushion is the reference piece most buyers start from on this material.
Thickness: the number everyone quotes and nobody defines
Two suppliers both offer an “8 cm” cushion. One measures at rest, uncompressed, on a table. The other measures under a 60 kg load. Those two cushions differ by a centimetre or more in real use, and the buyer comparing the quotes has no idea.
Ask which one you are being quoted. Then match thickness to the actual session length:
| Thickness | Comfortable session | Who buys it | Notes |
|---|---|---|---|
| 4 to 5 cm | 20 to 30 minutes | Floor dining, kids, decorative use | Stacks and stores easily; too thin for meditation |
| 7 to 8 cm | 45 to 60 minutes | Yoga, meditation, homestays | The volume sweet spot for most wholesale ranges |
| 10 to 12 cm | 90 minutes plus | Studios, floor-seating restaurants, zaisu chairs | Needs a firmer core or it collapses sideways |
| 15 cm plus | All day | Lounge seating, pouf-cushion hybrids | Heavy to ship; volume weight drives freight |
There is a second rule here that catches people out: above roughly 10 cm, a soft core fails sideways rather than downwards. A thick low-density cushion does not just compress, it spreads, and the sitter rolls off it. If you want a thick cushion you need a firm core — which is why the tall ones in our range are rush or corn husk rather than soft sponge.
Support, rebound and the number that predicts complaints
Rebound is how fast a cushion returns to shape after you stand up. It is the single best predictor of how long a customer stays happy, and almost nobody asks about it.
The test is simple enough to run on a sample. Press your full weight into the centre for ten seconds, stand up, and watch. A good core recovers within two or three seconds and shows no visible dent after a minute. A poor one leaves a crater that fills in slowly, and after a few hundred cycles it stops filling in at all.
Run that test on the sample, in writing, before you approve bulk. It takes thirty seconds and it will tell you more than any spec sheet.
Covers: removable is not the same as washable
A cushion with a zip is not automatically a washable cushion. Three details decide it.
Is there an inner liner? If the cover zips straight onto loose fill, the first wash sends the filling into the machine. A proper build has a separate liner holding the core, and the outer cover comes off over it. This is the single most common corner cut in the category, and it is invisible in photographs.
Where does the zip sit? A zip on the underside is clean but awkward to use. A concealed zip along one side is easier and, on a round cushion, nearly invisible if the tape is matched. Exposed metal zips on a floor cushion scratch wood floors and snag on rugs — worth avoiding regardless of cost.
What is the cover fabric, and has it been pre-shrunk? Cotton canvas and linen both move in the wash. If the cover is cut to the finished cushion size without allowance, it will not go back on after the first wash. Pre-shrinking costs a little and removes an entire category of review.
For hospitality programmes this is non-negotiable. A homestay or a studio will wash these covers weekly, not seasonally. Our round tufted seat cushion with a removable washable cover is built for exactly that duty cycle, in diameters from 40 to 80 cm so a single design can cover a stool, a floor seat and a bench.
Where these actually sell: three very different buyers
The same product page will not serve all three. Here is how the specification changes by channel.
| Buyer | Use pattern | Priority spec | Wrong choice |
|---|---|---|---|
| Yoga and meditation studio | Daily, 60 to 90 min, many users | Foam density and rebound, washable cover | Thin rush mat — too firm, cannot be laundered |
| Homestay, guesthouse, boutique hotel | Daily, short sits, high turnover | Removable cover, stain resistance, spare covers | Sealed cushion — one spill ends its life |
| Japanese restaurant, tea room | Daily, long sits, low tables | Rush surface, firm flat core, uniform colour | Soft sponge — diners sink and cannot rise comfortably |
| Home decor retail | Weekly, decorative first | Look, hand-feel, price point, gift packaging | Over-engineered commercial build — priced out of the shelf |
Note the last column. Almost every disappointing order we have seen was a good product bought by the wrong channel. A restaurant that buys meditation cushions gets unhappy diners. A studio that buys rush mats gets unhappy members. Matching the core to the use pattern is worth more than any negotiation on unit price.
Restaurants: the detail that gets missed
Floor dining has one specific requirement nobody puts on a spec sheet: the sitter has to be able to stand up again. On a very soft cushion, an older guest at a low table cannot rise without help. On a firm one they can. For any venue serving a broad age range, firm wins, and 8 to 10 cm of rush or corn husk over a board core is the specification we recommend.
Colour uniformity matters more here too. Ten cushions in a dining room are seen side by side under warm light; a shade variance that would be invisible in a retail photo reads as a defect in a row. We sort by shade within an order for this reason.
Shapes, sizes and the carry handle question
Round is the default and the easiest to place — it works as a floor seat, a stool top and a decorative object, and 40 to 45 cm is the size that sells across most markets. Square reads more architectural and stacks better in a restaurant. Rectangular zaisu-style cushions with a backrest are a different product again, and a strong upsell for floor-dining venues.
One feature punches above its weight: a carry handle. It sounds trivial. In a studio where 30 cushions are set out and cleared twice a day, or a homestay where guests move them between rooms, a handle is the difference between a product that gets used and one that gets dragged. Our square linen floor cushion with a carry handle and detachable cover exists because commercial buyers kept asking for it.
Custom sizes, colour and private label
Floor cushions are one of the easiest products in our range to customise. Diameter, thickness, cover fabric, colour, handle, piping and print all move without changing the fundamental construction, which means custom work does not carry the engineering cost it would on a more complex item.
Print is the option retailers under-use. A digitally printed linen cover lets a brand run a seasonal pattern or a logo at low minimums, on the same base cushion it already stocks. Our custom printed linen floor cushion is the route most private-label programmes take, and it is the fastest way to make a catalogue page look like your own product rather than a shared one.
The woven home mats category shows the full range of constructions we run — rush, straw, linen, cotton rope — which is the fastest way to see what the same silhouette looks like across materials before you commit.
Sampling, minimums and lead time
Our minimum is 50 pieces per design. Samples take one week. Production runs 30 to 45 days from confirmed specification.
What actually delays these orders is rarely the factory. It is a specification that arrives incomplete — a thickness with no density, a “washable cover” with no liner, a diameter with no tolerance. Each of those adds an email round trip, and three round trips is a month.
We have run handwoven home decor from our own 4,000 m² facility since 2014. The same rush, seagrass, jute, corn husk, water hyacinth and cotton rope fibres used across our basket range go into this category, so a buyer running both is working with one material vocabulary and one quality standard rather than two.
On testing, we arrange inspection and laboratory testing to whatever standard each buyer requires. Tell us the destination market and the standard your retailer or importer works to, and we will build it into the production schedule rather than bolting it on afterwards. On cushions specifically, we suggest confirming the requirement before sampling, so the sample you approve is tested to the same specification as the bulk that follows.
The specification sheet that prevents most disputes
Six fields. Put them on the purchase order and the conversation stays technical.
1. Surface material. Rush, corn husk, seagrass, linen or cotton rope. One answer.
2. Core and density. For foam, the density in kg per cubic metre. For natural fill, the fill weight.
3. Thickness and how it was measured. At rest or under load, and what load.
4. Dimensions and tolerance. Diameter by thickness for round, side by thickness for square, plus an accepted tolerance. Handwoven products move by a centimetre; say so up front and it stops being a defect.
5. Cover construction. Removable or fixed, inner liner yes or no, zip position, fabric, pre-shrunk yes or no.
6. Use case. Studio, homestay, restaurant or retail. This is the field that lets a supplier sanity-check everything above it, and it is the one buyers most often leave out.
Send those six and the quote comes back accurate the first time. Send “tatami cushion, 8 cm” and you will spend three weeks discovering that both parties meant something different.
Care, and what to tell your customer
Natural fibre cushions last years with almost no maintenance, but the instructions are not intuitive. Rush and seagrass should be wiped with a damp cloth and air-dried standing on edge — never left flat on a wet floor, and never submerged. Corn husk can take slightly more moisture but dislikes being saturated. Cotton rope and linen covers go in the machine on a cold cycle, and should be reshaped while damp.
Once or twice a year, flip the cushion. Fill migrates towards wherever people sit, and rotating it evens the wear out. We cover this in more depth in our cleaning and reshaping guide, and the underlying fibre behaviour is set out in the material guide.
Frequently asked questions
What is the minimum order for tatami floor cushions?
50 pieces per design. Custom sizes, colours and printed covers do not raise the minimum, though they do add to the unit cost because each variation carries its own setup.
Which core should I choose for a yoga studio?
High-resilience foam, 7 to 10 cm, with a removable washable cover over an inner liner. Specify the density in kg per cubic metre — thickness alone will not tell you whether the cushion survives a season of daily classes. Rush is the wrong choice here: it is too firm for long seated practice and it cannot be laundered.
Are rush cushions washable?
No, and this should be stated on your product page rather than discovered by the customer. Rush is wiped and air-dried. If your end customer expects machine washing, use a linen or cotton rope cover over a foam or cotton core instead. Buyers who want the tatami look with a washable build usually take a rush-look surface on a removable cover.
How thick should a floor cushion be?
Match it to the session length, not to the price. Four to five centimetres suits floor dining of 20 to 30 minutes. Seven to eight covers an hour of yoga or meditation and is the volume sweet spot. Ten to twelve is right for floor-seating restaurants and all-day use, provided the core is firm — a thick soft cushion spreads sideways and the sitter rolls off it.
Can you match a specific diameter and colour?
Yes. Diameter, thickness, cover fabric, colour, handle and piping are all adjustable on the base designs, and printed linen covers run at the same minimum. Send a physical reference or a Pantone value; a screen image is not reliable enough for a natural fibre that takes dye by batch.
Do these flatten over time?
Every cushion loses some loft. The question is how much and how fast. A rush or corn husk core will settle a few millimetres and then hold for years. Foam depends entirely on density: high-resilience foam recovers within seconds and holds most of its thickness for years of domestic use, while low-density foam can lose a fifth of its height within a year of daily commercial use.
How do you handle quality and compliance testing?
We arrange inspection and laboratory testing to whatever standard each buyer requires. Tell us the destination market and the standard your retailer or importer works to, and we will schedule it into production rather than adding it afterwards. For cushions we recommend confirming this before sampling, so the approved sample is tested to the same specification as the bulk order.
How long does an order take?
Samples take one week. Production runs 30 to 45 days from confirmed specification. The variable that most often delays an order is not production — it is a specification arriving without a density figure or a cover construction, which sends the order back to the buyer before a single cushion is cut.
Building a floor cushion range? Start from the woven home mats category to see the full material spread, then look at individual reference pieces: the handwoven natural rush cushion for the traditional tatami build, and the handwoven straw round pouf if you want height without a soft core. Our floor cushions in bulk guide covers the commercial side, and the wholesale buying guide walks through the order process end to end. For weave terminology to put on a spec sheet, see the weave and construction guide. Send us your thickness, core and cover requirements and we will come back with a quote and a sample schedule.
