Term What is it? / Characteristics Properties Benefits
Independent spring block with 4DSpring construction Spring block with 4D Spring construction, where springs are located in textile pouches that are interconnected in the centre, thus the upper and lower part of the spring are free to move in any direction. The springs respond to the slightest movement of the body. Due to this connection, the compression of one spring does not “pull” the compression of the neighbouring springs, which eliminates the “wave” and “hammock” effect. The springs in this block are designed for extreme loads and have no weight limitations. You do not feel your partner’s movements, even if there is a weight difference between two of you. As the springs are connected only in the centre, each spring is a separate zone of the mattress and adapts individually to the body, ensuring a comfortable sleep.
