UZit is the world's first clinically validated, surgeon-designed, patent-pending under-mattress elevation system. A gentle 5% full-body incline optimizes your circulation, reduces leg swelling, and supports recovery — every single night, while you sleep. No effort. No straps. No lifestyle changes. Just better sleep, better legs, and better mornings.
UZit was designed by a vascular surgeon to solve one of medicine's most overlooked problems: the human body was never meant to sleep flat. Whether you're managing a chronic condition, pushing your physical limits, or recovering from surgery — UZit gives your body what it needs most while you sleep.
Tired, Heavy Legs Keeping You Up at Night? There's a Clinical Solution.
Chronic venous disease affects one in two adults — and most people manage it with compression stockings, wedge pillows, and frustration. UZit is different. Clinically validated at the Faculty of Medicine, University of Porto, it creates a full-body incline that optimizes venous return all night long — the only solution proven to improve quality of life, reduce swelling, and eliminate the back pain caused by every other elevation device on the market.
Your Hardest Training Session Happens While You're Asleep.
While you sleep, your body flushes lactic acid, repairs muscle tissue, and rebuilds for tomorrow. The problem? Lying flat limits the circulatory efficiency needed to do it. UZit's full-body incline puts gravity to work for you — optimizing blood flow, reducing inflammation, and delivering oxygen to fatigued muscles all night long. Wake up fresher. Perform sharper. Recover faster — without adding a single minute to your routine.
Used by competitive triathletes, endurance athletes, and personal trainers across Portugal.
UZit is the only under-mattress elevation system backed by a peer-reviewed clinical study conducted at one of Europe's leading medical institutions. The randomized crossover trial, approved by the Ethics Committee of the Faculty of Medicine, University of Porto, demonstrated measurable improvements in circulation, quality of life, and leg swelling — with zero back pain and zero adverse effects reported.
Remove your UZit from the packaging and let the foam decompress for approximately an hour.
UZit sits completely hidden beneath your existing mattress, creating a precise 5% full-body incline. Your partner won't even know it's there.
While you sleep in any position — back, side, or stomach — UZit works. Circulation optimized. Muscles rebuilding. Zero back pain.
Dr. Sérgio Costa Pinheiro spent over 40 years as a vascular surgeon watching patients struggle with the same problem: every elevation device on the market caused back pain, disrupted sleep, and got abandoned within days. So he invented UZit — an under-mattress system that elevates the entire body, not just the legs, eliminating spinal instability regardless of sleep position. What began as a clinical solution is now available to everyone.
From the moment I started using the UZit device, I felt improvements in my legs. The swelling disappeared completely. My legs feel much lighter, and I sleep much better at night. I notice that when I wake up, I feel lighter and have more energy.
I feel that using the device maximizes nighttime rest, especially in the muscular recovery of the legs.
I woke up with a feeling of lightness, with both my legs and my mind more relaxed. I loved the experience. Thank you.
Daily use of this device significantly improved my day-to-day life, with a clear reduction in the feeling of fatigue I used to have in my legs.
Thank you!
Since I started using the mattress, I no longer have swollen or painful ankles. A whole summer has gone by, and even so my legs have remained in great condition. I am very satisfied.

UZit é compatível com todos os tipos de colchões standard — espuma de memória, molas e híbridos — em todos os tamanhos standard. Desliza por baixo do seu colchão atual sem necessidade de qualquer modificação.
Os participantes do estudo clínico relataram melhorias mensuráveis no inchaço das pernas e na qualidade de vida dentro de duas semanas de uso regular. Muitos utilizadores notam uma diferença na sensação de pernas pesadas pela manhã na primeira semana.
Sim. O UZit foi concebido para uso noturno e contínuo — esta é a sua principal vantagem em relação aos dispositivos de sessão curta. O ensaio clínico não reportou quaisquer efeitos adversos durante todo o período do estudo.
Não. A ausência de dores nas costas foi um resultado especificamente medido no estudo clínico da Universidade do Porto. Zero queixas de dores nas costas foram registadas durante o uso do UZit — em comparação com a dor lombar persistente que leva a maioria dos pacientes a abandonar almofadas em cunha e dispositivos de plataforma.
O estudo clínico incluiu doentes com classificações CEAP C1, C2 e C3 — abrangendo telangiectasia, varizes e edema. Se tiver CVD mais avançada (C4–C6), consulte o seu especialista vascular antes de utilizar. UZit foi concebido para complementar, e não para substituir, o tratamento prescrito por um médico.
A inclinação de 5% é suave e rapidamente se torna natural. Muitos parceiros sem doenças cardiovasculares relatam dormir melhor após um período inicial de ajuste de uma a duas noites. A inclinação de corpo inteiro da UZit afeta ambos os que dormem de forma igual e simétrica.
Sim — e recomendamos. A terapia de compressão e a elevação noturna são intervenções complementares na gestão de doenças cardiovasculares. O UZit proporciona a elevação sustentada que as meias de compressão não conseguem oferecer durante o sono.
A espuma UZit é fabricada em Portugal.
