Grahl Duo-Back 12

Grahl Duo-Back 12

The Grahl Duo-Back® 12 has a unique, two-part back rest which reduces pressure on the spine by up to 50%. The back rests are independently mounted, moving and flexing with the user. This dynamic movement has positive effects on the back muscles, metabolism, blood circulation and nervous system.


To benefit fully from a specialist chair, you will almost certainly need training to understand the best postures and habits. We recommend that you purchase training and setup when buying this product. This one-off charge (however many units you buy) includes assembly, configuration, full user training and removal of all waste packaging.

  • Streamlined design features a fully upholstered back.
  • Unique, patented back design supports the spine without direct contact.
  • Width-adjustable pads move in 3 dimensions and reduce pressure on the spinal column by up to 50%.  
  • Supplied with swivel-top armrests.
  • These chairs are made to order and delivery may take up to 6 weeks (we do not charge your credit card until we are ready to despatch).
