Twin System®
The Twin System technology is the expression of Dorelan’s excellence, uniqueness, innovation and experience. One coiled metal wire creates a double concentric spring that ensures perfect support for any body shape in any resting position. The external spiral, which is larger and softer, ensures comfort and ergonomics. On the other hand, the internal spiral, which has a smaller diameter, ensures support to heavier bodies, thus bringing the concept of independent spring to another level.
