The ERWIN M. Bonell spring core mattress provides a stable sleeping surface designed for durability and comfort. Its core consists of an 11 cm Bonell spring system combined with comfort foam, which is further enhanced by 3.5 cm of comfort foam and thermally bonded polyester fleece on both sides. This construction is available in two firmness levels to suit different needs: the H3 version supports a body weight of up to 140 kg, while the H2 option is intended for those up to 110 kg. The exterior is wrapped in a white, skin-friendly cover made from a blend of 63% polyester and 37% Tencel®, ensuring the material is gentle on the skin and allergy-friendly. For practical maintenance, the cover can be removed and divided thanks to a four-side zipper, and it is safe to wash at 60 °C, tumble dry on a gentle cycle, or dry-clean. The mattress also includes four turning loops to make rotating it easier and an additional bottom jersey cover that protects the inner core. Measuring 140 x 200 x 20 cm, this mattress arrives rolled in a cardboard box for convenient delivery via parcel service. It carries the OEKO-TEX® STANDARD 100 certification, confirming that the materials used are safe for your health and environment.
