The ERWIN M. Bonnell spring core mattress is designed to provide stable support for your nightly rest, featuring a 90 x 200 x 20 cm build. At its center is an 11 cm Bonnell spring core combined with comfort foam, which works alongside 3.5 cm comfort foam layers on both sides to balance firmness with a soft touch. This specific H3 model is built for those who prefer a harder feel and can support a weight of up to 140 kg. Its cover is crafted from a blend of 63% polyester and 37% Tencel, making the surface gentle on the skin and suitable for people with allergies. To keep the sleeping environment fresh, the material allows for very good aeration, and the removable, divisible cover with a four-side zipper can be washed at 60 °C. The mattress is finished with a jersey cover on the bottom and includes four turning loops to help you rotate it easily. Certified under OEKO-TEX® STANDARD 100, it arrives rolled in a cardboard box for convenient delivery via parcel service.
