A passion for better materials, innovation and craftsmanship. That is what characterizes this original American mattress. With a medium to firm top layer, it not only provides comfort, but also provides solid support (H3). On the inside of this mattress you will find the Firm Advanced Legget Springs. These are individually wrapped pocket coils with a noble size alloy. These springs are known for their very good counter pressure up to 150 kg per berth. The special Ergo Response in the spring of the American mattress ensures that you do not have to turn / turn the mattress. The strong exclusive fabrics used for this mattress are stylish, contemporary and have excellent elastic properties, for an extra enveloping, enclosed feeling. The edge of the mattress offers you a firm surface to sit on and also increases the usable sleeping surface, so that you seem to have more space.
