Read one twice? It's you. Or it's someone who would never buy it for themselves.
A far-infrared warming layer that lies under the fitted sheet and warms the body, not the room — the way ondol floors have warmed sleepers in Korea for three thousand years. It lives under the sheet all year, one button sets it, and it switches itself off. Not an electric blanket: no coil, no hot skin, no kicking it off at 2am.
Litual is the ondol topper we make in Seoul.the sun-warmed rock you stretch out on after an evening swim. The light gone, the air cool, the stone still holding the day.
01 · The stonelowering yourself into a bath that is exactly, precisely right.
02 · The bathfalling asleep warm against someone you love.
03 · 품Your body already knows how to rest. Litual only puts that moment where it belongs — in your bed, every night.
your side
their side
One controller, two sides. On the 150 and 180 cm, the left buttons set the left half of the bed and the right buttons the right — temperature and timer, each on its own. Here, 36 on one side and 50 on the other: one of you at barely-there, the other at deep. The thermostat negotiation ends here.
25–50°C (77–122°F) in single degrees · timer up to 12 hours, each side · 150 and 180 cm
Everything you'd want to ask, answered the way a care label would.
One side is hypoallergenic, breathable and soft to the touch — the side most of us sleep on. Flip it and the other side is fresh and airy, woven with cooling threads, for summer or for the one of you who runs hot. When the season changes, turn it over.
Cloud Sheet: FITI-certified, 0.01 mm pores — dust mites are 0.3 mm. Airy Sheet: OEKO-TEX® cooling threads, breathable. It sits under your fitted sheet, so think of it as a lighter, fresher warmth — not a cooling system.
Hold the button three seconds; it wakes with your last settings. 25–50°C in single degrees, a timer up to 12 hours, then it switches itself off. The 100 cm has a favourite button — your temperature and your hours, one press.
Runs on 24V DC — the low, steady current used in medical and skincare devices, chosen for what touches bare skin. No harmful EMF, from topper or controller. Full power for the first 30–60 minutes, then under 1 watt: a night costs about two slices of toast.
Any mattress — spring, latex, foam, roll-up. Lay it on top, connector at the headboard, fitted sheet over it, duvet on top. Done, once.
Children, new mothers and people in their eighties already sleep on it. Pregnant, or living with a health condition? A two-minute question to your doctor, then stop thinking about it.
Most nights, nothing — it lives under a sheet. Now and then, a wipe. When it needs more: unplug, detach the cap, hand-wash cold, or a gentle machine cycle in a laundry net — a few times over its life is plenty. Reshape while damp, air-dry. The far-infrared yarn is Teflon-coated and waterproof. Off-season, it folds to the size of a bag.
No tumble dryer, iron or bleach.Warmth does the work — not you.
Built like hotel bedding, with a warm secret inside.
FITI-certified hypoallergenic weave, matte and crisp. Keeps dust out of your bed.
Hypoallergenic microfibre. Plush, and even warmth with no hot spots.
2,000+ fine fibres twisted into one flexible thread, Teflon-coated, hand-sewn in Seoul. No adhesive, no plastic. The heart of it.

Two founders, no middlemen. Min runs Kozy from Paris. Miye, with thirty years in textile manufacturing, runs production in Seoul — small batches, on a floor we run ourselves. Stocked by Evezary, Korea's leading bedding retailer, and exported to Japan. Selected by La French Tech; INSEAD Launchpad at Station F.
Meet us →Owners carry it to hotels, to conferences, to a friend's spare room — and pay the airline for the extra bag. The first night in a strange bed is the night they least want to be cold.
Folded, it is the size of a weekend bag. The cable and controller go in the pocket.
Almost no one comes looking for a heated topper. They come because someone who has one wouldn't stop talking about it. Then the same thing happens to them: a week in, they can't remember how they slept before, and they don't want to find out.
We assumed people would fold it away in April. They didn't. Nine in ten keep pressing the button in June — not to get warm, they told us. Because something loosens. The shoulders. The jaw. The breath that finally goes all the way down.

The first night I turned on the topper, I actually cried. It was the first time all day I felt completely held and allowed to just… stop.Elena R. · Milan
솔직히 처음엔 전기장판이랑 뭐가 다른가 싶었는데, 써보니까 차원이 다릅니다. 잠들기까지 1시간 걸리던 게 15분으로 줄었어요.정민수 · 서울
On a tout essayé — mélatonine, magnésium, meditation apps. Le surmatelas a changé nos nuits en une semaine. C'est profond, enveloppant.Amélie D. · Paris
I track everything with my WHOOP. Strain, recovery, deep sleep — you name it. I was doing all the 'right' routines and still waking up destroyed. Within a week of using the pad, my Deep Sleep went from 45min to 1h40. That's insane ROI on something I literally do nothing for.
Sarah M. · ✓ VerifiedI have two herniated discs and sleeping has been absolute hell for years. The far-infrared heat from the heated topper genuinely loosens up my lower back in ways physio sessions don't. I wake up with maybe 30% less stiffness. Over time it's been transformative.
James K. · ✓ Verified어릴 때 할머니 집 온돌방에서 자던 느낌이에요. 그때처럼 바닥에서 올라오는 따뜻함이 아니라 매트리스 위에서 느껴지는 건데, 그 깊은 온기가 정말 비슷해요. 겨울에 특히 최고입니다.
박지영 · ✓ VerifiedI've spent thousands on mattresses, pillows, sleep trackers. The litual did more for my sleep quality in one week than all of those combined. The dual-zone feature is genius — my wife likes it warm, I like it cooler. Everyone's happy.
Marcus L. · ✓ Verified日本の電気毛布を何枚も使ってきましたが、Litualは全く別物です。体の芯から温まる感じで、朝起きた時の体の軽さが違います。特に冬場は手放せません。夫婦で別々の温度に設定できるのも最高です。
田中美咲 · ✓ VerifiedI've been dealing with anxiety-related insomnia for years. After two weeks with Litual, my therapist actually commented that I seemed calmer and more rested. I'm sleeping deeper and waking up without that dread feeling. It's not a cure, but it's a genuine tool in my toolkit.
Charlotte V. · ✓ Verified간호사라 3교대 근무하는데, 낮에 자야 할 때 깊은 잠을 못 자서 항상 피곤했어요. 리추얼 토퍼 깔고 나서는 낮잠 질이 완전히 달라졌습니다. 4시간 자도 6시간 잔 것 같은 느낌이에요.
이준호 · ✓ VerifiedThe science behind this is solid. Took me about 3 nights to find my ideal temperature (settled on 34°C). Once I dialed it in, the difference was night and day. Literally. Only dock one star because the manual could be more detailed for us nerds who want to understand every feature.
David H. · ✓ VerifiedMenopause destroyed my sleep. Hot flashes, night sweats, the works. With the pad set to a lower temp on my side, I'm finally sleeping through the night again. It's been life-changing. My husband keeps his side warmer and we're both happy.
Sophia K. · ✓ VerifiedTengo problemas crónicos de espalda y mi fisioterapeuta me habló del infrarrojo lejano. Después de investigar, elegí Litual. Los resultados son increíbles — me despierto sin rigidez y mi recuperación muscular ha mejorado notablemente. Lo recomiendo a todos mis compañeros de gimnasio.
Carlos M. · ✓ VerifiedFrom the packaging to the stitching to how it feels — you can tell this is a premium product. It's not some cheap heated blanket from Amazon. The fabric, the controller, the way the heat distributes evenly. Worth every penny.
Olivia P. · ✓ Verified추위를 많이 타시는 시어머니께 드렸는데, 전화로 한참 좋다고 하셨어요. 관절도 덜 아프다고 하시고, 밤에 깨는 횟수도 줄었다고 합니다. 효도 선물로 강추합니다.
김태희 · ✓ VerifiedIs it expensive? Yes. Is it worth it? Also yes. I was hesitant about the price but the build quality justifies it. I've had mine for 4 months now and the improvement in my sleep quality is measurable with my Oura ring. Deep sleep up 40%, resting heart rate down.
Maximilian R. · ✓ VerifiedI used to pile on 3 blankets and still feel cold at night. Litual replaced all of them. The warmth is different — it comes from within, not from trapping air. I sleep with just a light duvet now and I'm perfectly comfortable at -15°C outside.
Emma S. · ✓ Verifiedキングサイズを購入しました。妻は38度、私は30度で設定しています。お互い快適な温度で眠れるのが素晴らしいです。以前は妻が暑がりの私に合わせて寒い思いをしていたので、本当に助かっています。
山田健太 · ✓ VerifiedMy boyfriend is a furnace, I'm always freezing. We used to fight about the thermostat every night. Now he has Zone A at 26°C and I have Zone B at 38°C. Peace has been restored in our household. Best relationship investment ever.
Laura B. · ✓ VerifiedIT 개발자라 하루종일 앉아서 일하고 밤에 잠을 잘 못 잤는데, 토퍼 쓰기 시작한 후로 수면의 질이 확 달라졌어요. 아침에 일어날 때 개운한 느낌이 확실히 다릅니다.
최현우 · ✓ VerifiedAfter 3 weeks of sleeping on the heated topper, my chiropractor noticed my back tension had decreased significantly. He actually asked what I'd changed in my routine. The far-infrared warmth genuinely helps with muscle recovery overnight.
Isabella F. · ✓ VerifiedFunctionality is perfect. Sleep quality improved dramatically. My only wish is that it came in different cover colors to match my bedding better. A minor aesthetic thing, but when you're paying premium you notice these details.
Henrik J. · ✓ VerifiedInsomniaque depuis une décennie. J'ai essayé tout — somnifères, ASMR, méditation. Le topper m'a permis de retrouver un sommeil profond et réparateur en moins de deux semaines. Je ne m'endors plus en 2 heures mais en 20 minutes. C'est miraculeux.
Marie-Claire P. · ✓ VerifiedAs a nurse working nights, sleeping during the day was always rubbish. The warmth from the mattress topper helps me fall asleep faster and stay asleep longer during daytime. My recovery between shifts has improved massively.
Oliver T. · ✓ Verified제주도는 습하고 추운 겨울이 길어서 항상 잠자리가 불편했는데, 리추얼 덕분에 편안하게 자고 있어요. 습기가 차는 느낌도 없고, 온기가 깊이 퍼지는 게 일반 전기장판과 완전히 달라요.
박서연 · ✓ VerifiedSufro de fibromialgia hace 5 años y las noches eran terribles. Desde que uso el topper, el dolor nocturno ha disminuido mucho. El calor infrarrojo penetra de una forma que ninguna manta eléctrica convencional puede. Mi reumatóloga está impresionada con la mejora.
Ana G. · ✓ VerifiedI spent €2,000 on a memory foam mattress. It's fine. But this topper, at a fraction of the cost, has improved my sleep more dramatically. Deep sleep went from 1 hour to nearly 2 hours according to my Fitbit.
Benjamin R. · ✓ VerifiedBefore the pad: avg Deep Sleep 48min, HRV 35. After 1 month: avg Deep Sleep 1h22, HRV 52. I didn't change anything else in my routine. The numbers don't lie.
Natasha K. · ✓ Verified효과는 확실합니다. 수면 질이 올라간 건 분명해요. 다만 가격대가 좀 있어서 고민을 많이 했습니다. 결론적으로 산 건 잘한 선택이었지만, 좀 더 합리적인 가격이었으면 하는 아쉬움은 있네요.
김유진 · ✓ VerifiedAs a general practitioner, I'm cautious about recommending products. But the FIR technology is well-researched and the quality of this product is exceptional. I've recommended it to several patients with chronic pain and poor sleep, and the feedback has been universally positive.
Lucy W. · ✓ Verified長年の腰痛で整形外科に通っていましたが、Litualを使い始めてから朝の腰の硬さが劇的に改善しました。遠赤外線の効果を実感しています。妻も冷え性が楽になったと喜んでいます。
鈴木大介 · ✓ VerifiedMy partner got this for me on Valentine's Day. Initially I thought it was an odd gift. Now it's the best thing in our bedroom (after him, of course 😄). We both sleep so much better. The dual-zone feature is genius for couples.
Patricia N. · ✓ VerifiedI used to take 1-2 hours to fall asleep every night. Now I'm out in 15-20 minutes. The gentle warmth creates this cocoon feeling that my nervous system apparently needed. No pills, no apps, no routines. Just warmth.
Sebastian M. · ✓ Verified임신 중 허리 통증이 심했는데, 낮은 온도로 설정해서 사용했더니 정말 편안했어요. 의사에게 확인하고 사용했습니다. EMF 프리라서 안심이 됐고, 24V 저전압이라 더 안전하게 느껴졌어요.
이소영 · ✓ VerifiedProduct is fantastic — sleep quality measurably improved. Knocked one star because delivery took 12 days to Scotland. But the product itself? Absolutely brilliant. Would buy again.
George P. · ✓ VerifiedAprès des années d'insomnie chronique, Litual a changé ma vie. La chaleur infrarouge est douce et profonde, pas comme une couverture chauffante qui surchauffe. Je m'endors en 15 minutes maintenant, contre plus d'une heure avant.
Clara D. · ✓ VerifiedWas worried about international shipping but it arrived in perfect condition. The build quality is outstanding. My chronic shoulder tension is noticeably better in the mornings. My physiotherapist is impressed with my progress.
Ryan O. · ✓ Verified여름에 에어컨 세게 틀고 자면 항상 어깨가 뻣뻣했는데, Litual을 낮은 온도로 설정해놓으니 에어컨 바람에도 체온이 유지돼서 너무 좋아요. 사계절 다 쓸 수 있는 게 최고의 장점입니다.
강다은 · ✓ VerifiedAs a Finn, I love my sauna. The litual extends that deep warmth feeling into my bed. The far-infrared is similar in concept to a sauna but gentle enough for all-night use. My sleep latency dropped from 45min to about 12min.
Nina S. · ✓ VerifiedI'm a data person. After 30 days with the mattress topper, my Apple Watch shows: avg time to fall asleep dropped from 38min to 14min, deep sleep increased 42%. I changed nothing else. This is the only variable. Convinced.
Michael B. · ✓ Verifiedひどい冷え性で冬は眠れない夜が続いていました。Litualを使い始めてから、足先まで温まって朝までぐっすり眠れるようになりました。遠赤外線の温かさは本当に体の中から温まる感じです。もう手放せません。
佐藤麻衣 · ✓ VerifiedHot flashes ruined my sleep for 2 years. Setting the topper to a lower, consistent temperature stabilized my nighttime body temp. No more waking up drenched. I feel like myself again.
Hannah G. · ✓ Verified크로스핏을 하는데, 리추얼 쓰기 시작한 후 다음 날 근육 회복이 확실히 빨라졌어요. WHOOP 데이터로도 회복 점수가 10% 이상 올랐습니다. 운동하는 분들께 강력 추천합니다.
윤서준 · ✓ VerifiedI used to need multiple heavy blankets in Norwegian winter. Now I just use a thin duvet over the pad and I'm perfectly warm. The weight off my chest alone improved my breathing during sleep.
Ingrid K. · ✓ VerifiedAppena aperta la scatola si capisce che è un prodotto di alta qualità. I materiali sono eccellenti, il calore è uniforme e profondo. Dopo un mese il mio mal di schiena cronico è migliorato significativamente. Lo consiglio a tutti.
Roberto F. · ✓ VerifiedI hesitated because of the price. But after 6 weeks, my sleep quality has improved enough that I feel noticeably more productive during the day. The ROI is real. Just wish it was a bit more affordable so more people could access it.
Alex M. · ✓ Verified놀랍게도 남편 코골이가 줄었어요! 아마 수면 자세가 편해지면서 기도가 덜 좁아진 것 같아요. 저도 깊은 잠을 자게 됐고, 아침에 둘 다 개운하게 일어납니다.
장미란 · ✓ VerifiedStarted with one for myself. Mom tried it when she visited, ordered one the next day. Sister followed. Dad is next. It's becoming a family affair. The quality is undeniable.
Eva L. · ✓ VerifiedSceptique au départ, j'ai été convaincu après une semaine. Mon sommeil profond a augmenté de 35% selon mon Oura Ring. La chaleur est douce, enveloppante, et jamais excessive. Un vrai investissement pour la santé.
Pierre M. · ✓ VerifiedI thought I slept fine. Then I got the topper and realized I'd never actually experienced deep, restorative sleep before. The difference in my daytime energy, mood, and focus is remarkable. I'm sharper at work and calmer at home.
Daniel S. · ✓ Verified한의원에서 원적외선 치료를 받다가 원장님이 집에서도 쓸 수 있는 걸로 Litual을 추천해주셨어요. 냉증이 심했는데 확실히 손발이 따뜻해지고 수면 질이 좋아졌습니다.
김하윤 · ✓ VerifiedI've tried melatonin, magnesium, L-theanine, CBD — you name it. None of them produced the consistent results the pad has. It's not a supplement, it's an environment. And environments are more powerful than pills.
Marta W. · ✓ VerifiedAs someone in tech, I appreciate the engineering. The dual-zone system works flawlessly, temp control is precise, and the auto-shutoff gives peace of mind. Minor nit: would love an app for scheduling and tracking. But the hardware alone? Top notch.
William R. · ✓ Verified産後の冷えと体の痛みに悩んでいましたが、Litualのおかげで夜しっかり眠れるようになりました。授乳で何度か起きても、温かいベッドに戻るとすぐにまた眠れます。産後のお母さんにお勧めしたいです。
中村優子 · ✓ VerifiedI run marathons and ultramarathons. Recovery sleep is everything. The litual has noticeably improved my post-race recovery. Muscles feel looser in the morning, and my Garmin shows better sleep scores across the board.
Chris D. · ✓ Verified아이가 겨울에 이불을 잘 차서 걱정이었는데, Litual을 깔고 나니 이불을 차도 따뜻해서 안심이에요. 낮은 온도로 설정해놓으면 아이에게도 안전하고 편안합니다.
이민지 · ✓ VerifiedHard to find premium sleep products in Slovenia. Ordered from the website and it arrived in 5 days. Quality exceeds anything locally available. My rheumatologist was curious about it and is now looking into FIR therapy for her patients.
Katarina V. · ✓ VerifiedYou'd think a heating pad is useless in Dubai. Wrong. Indoor AC is freezing at night. The topper at 28°C creates the perfect microclimate under the covers while the room stays cool. Best purchase of the year.
Ahmed K. · ✓ VerifiedPadezco de artritis reumatoide y las noches son difíciles. This topper me ayuda a despertar con menos rigidez y dolor en las articulaciones. El calor infrarrojo es suave pero penetrante. Mi reumatólogo quedó sorprendido con la mejora en solo un mes.
María T. · ✓ VerifiedSleep quality improved significantly. The heat distribution is even and the dual-zone works well. I'd love to see a slimmer controller and maybe a phone app in the future. But for what it is right now, it's excellent value.
Frank B. · ✓ VerifiedFitbit 수면 점수가 리추얼 사용 전 72점에서 사용 후 89점으로 올랐어요. 특히 깊은 수면 시간이 거의 두 배가 됐습니다. 데이터로 증명되니까 더 확신이 생겨요.
정아름 · ✓ VerifiedI bought my my Litual in early 2023 and it's still going strong. The quality holds up beautifully. I wash it monthly and it looks brand new. Two winters in and my sleep quality remains consistently better than before. This product lasts.
Victoria A. · ✓ VerifiedLong conversations with the people who sleep on Litual — how they found it, what changed, what they'd tell you. Not testimonials. Portraits.
Anyone who sleeps on one can write. A line or a paragraph, a photo if you like — we verify it against a purchase and publish it as you wrote it.
A far-infrared warming layer that lies under your fitted sheet and warms the body, not the room. The name comes from ondol (온돌), Korea's warmed floor: for three thousand years Koreans have slept with cool air above and steady warmth below, and an ondol topper brings that arrangement to any bed. It is not an electric blanket — there is no coil heating the surface. Far-infrared yarn woven into the topper sends warmth about 4 cm into the body, one button sets it, and it switches itself off. Litual is the ondol topper we make in Seoul.
No. Electric blankets heat your skin, which is why they get kicked off at 2am. Litual's warmth goes deeper while your skin stays comfortable. Keep the room cool, warm only the bed. Start around 27°C on the first night, then find your own number.
A blanket is a coil that heats the surface. Litual is far-infrared: it warms the body itself, the way late sun warms a stone. No overheating, no dryness. Touch it with your hand and it may not feel like much — lie on it, and it does.
Most of the time, a wipe. When it needs more: unplug, detach the cap, hand-wash cold, or a gentle machine cycle in a laundry net — a few times over its life is plenty. Reshape, air-dry. No dryer, iron or bleach.
Go by the width of your mattress, not by the name — names change from country to country. 100 cm (39 in) is what other countries call single, twin or super single; 150 cm (59 in) double or queen; 180 cm (71 in) king. All are 200 cm / 79 in long. It doesn't have to match exactly: a little wider than the mattress tucks under the fitted sheet with the edges; a little narrower sits centred with a margin on each side. You won't feel either once you're lying on it. Still unsure? Tell us your mattress when you reserve and we'll choose with you. The 150 and 180 cm warm each side of the bed separately, from one controller.
Those systems pump water through a cover to heat or cool the surface. They need a unit on the floor, an app, and usually a subscription. Litual is the opposite kind of thing: a quiet layer under the sheet, no pump, no app, nothing to pay after the box arrives. And it doesn't try to cool you. It warms the body with far infrared so your core lets go and cools itself — which is what deep sleep actually needs. Cool the room. Warm the bed.
Because of what is inside and who makes it. The far-infrared vein is two thousand fine fibres twisted into one thread and hand-sewn in Seoul, on a floor we run ourselves, in small batches — no factory in between, no warehouse. It carries a 2-year warranty, and the first owners are on their third winter with theirs. Spread across five winters, that is well under fifty cents a night. The 100 nights are there so you can decide with your body, not with the price tag.
Reservations close on the last day of each month for the next month's batch. Within 48 hours of reserving we confirm your size and send the payment link with the confirmation; once it's paid, your Litual goes into the batch and ships from Seoul the following month. The 100 nights start the night it arrives, not the day you pay.
No. For a limited time shipping is free worldwide, and we ship with duties and taxes paid, so the price you see is the price you pay — nothing to settle with the courier. If your country isn't in the region list when you reserve, write to us first and we'll confirm before you commit.
100 nights, no questions asked. Send it back from wherever you are and we refund the full price — the only thing you cover is the return postage. Every Litual carries a 2-year warranty.
Lie down. Press one button. Warmth does the work.
