Pinpoint dynamic sitting: Sedus black dot stands for long-lasting quality, sophisticated design and numerous feature options. Sitting still for a prolonged period of time takes its toll on the body and on our mental performance. Thanks to the flexibility of the Sedus dorsokinetic mechanism, the user stays mobile and always in balance. This is good for the intervertebral discs, and relaxes the neck and back muscles, allowing the head to move freely.
