Made in Germany, quality guaranteed. The Hyper Air Hybrid upholds the brand's tradition of excellence. Meticulously crafted by German artisans, its exquisite craftsmanship permeates every detail. Combined with world-leading patents and technologies, it is engineered to redefine the standard of quality sleep, achieving unparalleled pressure relief and support. Airline© Self-inflating foam-in-cell technology, combined with a multi-layer pressure relief system featuring Ecolast®, Geltouch®, and Memoline© Viscoelastic technologies, merges sophisticated tech with ultimate quality to provide what can be called perfect comfort, bringing you a pressure-relief effect unique to the market. German-made Ecolast® medical-grade pressure-relief material evenly disperses pressure across all pressure points of the body (such as the head, shoulders, elbows, lumbar spine, hips, heels, etc.), providing relief and effectively preventing the formation of pressure sores, as well as alleviating existing pressure sore issues. The Ecolast® More Open Cell structure is more breathable, offers better pressure relief, and is more durable than traditional foam layers. Superior support capacity, with a weight limit of up to 551.2 lb / 250 kg. Greenline© Ecolast® production technology reduces carbon dioxide emissions by approximately 22% compared to traditional methods, achieving "Environmental Protection 4.0". Two major differences from standard air mattresses: The middle layer of air cells uses self-inflating foam-in-cell technology, eliminating the risk of failure. No external air pump or power supply is required. Suitable For Stage 4 pressure sores (wounds may be deep enough to expose bone). According to the European Pressure Ulcer Advisory Panel (EPUAP). Long-term bedridden individuals at very high risk of developing pressure sores. According to the Norton, Braden, and Waterlow Scale pressure sore risk assessment charts. Pain therapy. Post-surgery recovery. Structure Top Layer: "Ecolast® Foam Layer" Utilizes "breathable open-cell technology" to promote air circulation, achieving an optimal microclimate by maintaining comfortable temperature and humidity. Durable and long-lasting material. More environmentally friendly: The manufacturing process reduces CO2 emissions by approximately 22% compared to traditional foam mattresses and air beds. Super-soft head support to relieve pressure on the head. Sloped heel design to relieve pressure on the heels. Middle Layer: Divided into the following 4 sections The head section features "Geltouch® technology" to maintain temperature. The middle section consists of 8 "self-inflating foam-in-cells" to enhance pressure relief. The foot section is made of "Visco foam" (memory foam) for soft comfort. The sides are made of a higher-density, firmer foam layer to protect the softer middle layers and provide stability by preventing outward bulging under pressure. Bottom Layer: High-density, firm foam layer that provides overall support. PU Protective Cover (Ultrasonically Welded) Breathable (maintains microclimate), anti-bacterial, waterproof, and fire-retardant. 4-way stretch (Bi-elastic) quality reduces shear force to prevent skin damage. 3-sided zipper design for easy removal and changing. Washable at 95°C and autoclavable according to the German Robert Koch Institute (RKI) guidelines to maintain hygiene. Inflation Instructions Pull the blue valve cap backward for about 5 minutes until fully inflated (do not pull the entire cap off). Push the blue valve cap forward to close the valve. Have the user lie down on the mattress. Pull the blue valve cap backward again to release air until the most comfortable level is reached (test by placing a hand, palm up, between the user's buttocks and the mattress; there should be just
