The patented bridge® technology of Swissflex enables fully automatic and optimal adaptation to the human body, regardless of stature and weight. The free-swinging surface provides pressure relief effectively in problem areas such as the shoulders and supports the body at the same time in the right places and over the entire lying surface. The heart of the bridge® technology is a chain of spring modules, which gives the slat base an exceptional flexibility. Connected by a flexible adapter, these modules provide a connection between the slats. This results in automatic and controlled pressure relief and support along the longitudinal axis.
