Why should I choose a mattress of natural materials and not of metal springs?
Mattresses without springs are comparatively superior to those with springs. Natural materials offer even, isometric body support and do not contain noise sources. On the contrary, springs give different support to their points of connection than in the middle of each separately. Also, despite the fact that they are dressed with cotton, it is more possible to produce noise because they are made of steel.
In addition, natural materials last longer. Their resilience through time, not only because of their natural origin but also because of their characteristics (elasticity, reset), it is larger than the resilience of the springs which are artificial.
Finally, natural materials have bigger resilience in heavy and careless use and do not produce magnetic fields. Every kind of metal generates even a minor magnetic field.
