Duo Basic is a very tough and robust slatted bed base. Its mid-zone springiness can be varied, thus the bed frame can be individually adapted to your body weight and sleeping position. Thanks to the reinforcing belt in the middle, it is suitable for weighty people, too. The most amazing feature about this bed base is that it is completely untreated - no glaze, nor oil, nor wax. Therefore, it is very breathable and pertfectly suits our offer of high-quality natural mattresses.
