Seating models from the original DuoBack® range!  

The unique back rest that is recommended by Physiotherapists, Osteopaths and Health Professionals worldwide

Scientific studies have shown that DuoBack® reduces pressure on the spinal discs by upto 50%.  It has positive effects on the back muscles, metabolism, blood circulation and the nervous system.

The back rest pads are independently mounted and flex and adjust to your back as you make changes to your posture.  They offer continual adaptive support for your back throughout your day.

Many of our clients have had their DuoBack for 10+ years and swear by the design.  If you have damage to your spinal discs, have had a back operation or maybe suffer from scoliosis, the DuoBack® chairs are definately one to consider.
