grahl type 12 chair

Grahl Type 11 and 12 Duo-Back Ergonomic Office Chair

The DuoBack 12 office chair has a fully upholstered outer back. That is the only difference between  these superb little chairs.
The DuoBack Type 11 and DuoBack Type 12 chairs have brought so much relief to so many of our clients.  Post operation, Scoliosis and ‘bad backs’ in general are where these two chairs shine through above the competition.</

They are the Original DuoBack office chairs! which have served many people well over numerous years.
The difference between the two models is the finish of the back rest pads.  The Type 11 has plastic shells, the Type 12 is fully upholstered, that’s it, nothing else changes.

The two flexible Backrest supports move individually to adapt to every movement that your back makes. The Grahl Type 11 supports variation between exertion and relaxation at the work place, so that a relaxed feeling is maintained.

The uniquely designed backrests only come into contact with the musculature. This prevents pressure on the spine, sacrum and invertebral discs by approximately 50% more than standard backrests. The Grahl Type 11 has 3 models available, the standard, the Grahl Type 11 with large seat and the Grahl Type 11 high chair
