The ERWIN M. Hybrid Core All-in-One Advanced is a versatile hybrid mattress designed to adapt to different sleep preferences through its dual-sided firmness. One side offers a medium H2 feel, combining a 2 cm comfort foam layer with 4 cm of gel foam that provides a memory effect to contour to your body. For those who prefer more support, the H3 firm side features 4 cm of cold foam and is built to accommodate body weights up to 140 kg. At its center is a reinforced 7-zone pocket spring core with 12 cm high springs, featuring a density of 480 springs per 2 m² to ensure targeted support across the body. This core is wrapped in a white cover made from a blend of 63% polyester and 37% Lyocell (Tencel®), which is skin-friendly and suitable for allergy sufferers. The design includes a four-sided zipper for easy removal and four grip tabs that make turning the mattress much simpler. Measuring 90 x 200 x 25 cm, this mattress focuses on temperature equalization through high ventilation. It is certified under OEKO-TEX® STANDARD 100, ensuring the materials are safe for your skin. For maintenance, the cover can be washed at 60 °C on a gentle tumble dry setting, though you should avoid chlorine or bleach. The product arrives rolled in a cardboard box for convenient delivery via parcel service.
