The Best Futon Mattresses

Three different products, one search term

This is the problem with buying a futon mattress and the reason most people end up with the wrong one. "Futon mattress" is used for three unrelated things, and a single search returns all of them mixed together:

• A Western futon-frame mattress. A thick cushion built to sit on a hinged frame that folds between a sofa and a bed. This is what most American buyers mean, and it is what three of the five picks here are.
• A Japanese floor futon, or shikibuton. A thin cotton mat that goes on the floor at night and into a closet in the morning. The original meaning of the word, and a genuinely different product — thinner, firmer, longer, and wrong on a frame.
• A tri-fold guest mattress. Not a futon at all, but half the people searching for one want this: a foam mattress that folds into thirds and stands in a closet until somebody visits.

Decide which of those three you are buying before you compare anything else, because the specs that matter are different for each. Thickness matters most for the frame mattress. Length matters most for the floor futon. Fold geometry and storage matter most for the guest bed.

The sizes do not match, and that is the main thing to know

Here is what the listings on this page actually publish:

• Milliard full-size futon mattress: 71 x 52 x 6 inches
• D&D Japanese floor futon, full size: 80 x 54 x 3 inches
• Milliard trifold, queen size: 78 x 58 inches

Two products both labeled "full" differ by nine inches in length and two in width. That is not a misprint on anyone's part — it is the consequence of three product traditions sharing one set of size names. A futon frame is built for a specific mattress footprint, and a mattress cut nine inches short of the deck will look wrong, slide, and leave a lip of bare frame at the end of the bed.

So: measure the deck of the frame, length and width, write it down, and buy only from a listing that publishes inches. A listing that says "full" and nothing else is not telling you enough to buy safely, which is one of the reasons the pick at the top of this page is the one that publishes its dimensions. Standard bed sizes are a different chart and do not reliably apply here.

Thickness is the comfort decision, and it trades against folding

Everything else about a futon mattress is secondary to how thick it is.

Three to four inches is floor-futon and guest-bed territory. Firm, storable, and thin enough that a side sleeper feels the surface underneath at the hip and shoulder. Correct for its purpose, wrong as a permanent bed for most people.

Six inches is the standard futon-frame thickness: enough to sit on comfortably, enough to sleep on occasionally, still foldable without a fight. This is the right answer if the futon is a sofa that sometimes becomes a bed.

Eight inches is the nightly-sleep thickness, and the point at which the thing stops feeling like a cushion. The same thickness logic that governs bed mattresses applies, compressed into a narrower range. The cost is that folding an eight-inch mattress over a hinge every morning is work, and you will stop doing it.

The fold is what kills these mattresses

A futon mattress does not usually wear out across its surface the way a bed mattress does. It fails at the hinge. Fold the same foam in the same place every morning for two years and that line becomes a permanent crease with less loft than the rest of the mattress, which you then feel across your lower back every night.

Two things help. The first is construction: a tufted mattress — stitched through with ties, like the MAXYOYO pick — handles folding better than a smooth foam slab, because the ties hold the fill in place rather than letting it migrate away from the crease. The second is to stop folding it. If the futon is somebody's actual bed, leave it flat in the bed position and treat the frame as a bed frame. The sofa mode is the feature that destroys the mattress.

How the five compare, from the listings

Three of the five publish exact inches. Two publish a foam certification. Two publish a washable cover. The ranking follows those three columns, because on a shelf this unstandardized, what a seller is willing to put in writing is most of the information available.

Foam, cotton, or something unspecified

Memory foam is the common Western futon fill now. It is comfortable, it conforms, and it is the worst of the three at being folded. CertiPUR-US certification on a foam futon means the foam was tested against a published list of substances it may not contain — worth having, and two picks here state it.

Cotton is the traditional floor-futon fill. It is firm, it breathes, it compresses over years rather than months, and it needs airing to stay dry. If you want the thing a futon originally was, this is it.

Unspecified fill is most of this shelf. A listing that states a thickness and a size and nothing about what is inside is telling you it is a commodity product, which is fine at commodity prices and the reason the budget pick here sits where it does rather than higher.

If it is going on the floor

Cotton floor futons are designed for it. Foam is not, and the reason is moisture rather than comfort: body vapor passes down through foam overnight, meets a cold floor that cannot absorb it, and condenses underneath — which over a season is how a mattress grows mold on the face you never look at. Traditional futons get folded and aired every morning precisely because of this. The full version of that problem applies to any foam mattress on any floor.

If a foam futon mattress is living on the floor, stand it against a wall regularly so both faces dry. If that sounds like a chore you will not do, buy the cotton one.

Can you make a futon more comfortable?

Up to a point, and the honest answer is that a topper fixes softness but not thinness. Adding two inches of foam over a six-inch futon gives you a softer surface and a bit more distance from the deck, which helps a side sleeper at the shoulder — and a topper is a cheap experiment compared with a new mattress. What it cannot fix is a mattress that has bottomed out at the fold line or compressed flat in the middle. At that point the topper is sitting on the problem rather than solving it.

If the futon is a permanent bed for a student or a guest room, the dorm mattress page and the guest room page cover the alternatives that are not futons, which are often cheaper per year of use than replacing a futon mattress twice.

About the prices on this page

We do not type prices into pages. Each button carries a figure read from the live listing by our own price check, stamped with the date it last ran. This shelf prices by size and by cover color on the same listing, and the spread between a twin and a queen is large, so check which variant is selected before you buy.

What we will not tell you

We have not slept on these five and we have no test lab. The ranking is built on what each listing publishes — exact dimensions, thickness, fill and certification, cover removability — and on what those properties do in use: thin mattresses transmit what is underneath them, foam creases where it folds, tufting resists migration, and a cover that comes off gets washed. Our full method is here. Where a listing does not state something, this page says so rather than guessing.
