Grahl Type 11 & 12 Duo-Back Chair


Grahl Type 11 & 12 Duo-Back Chair

The perfect backrest has to fulfil two apparently contradictory criteria:
It should not only support the upper body and take over the functions of the muscles which support the back; but also follow and facilitate the movements of the upper body.

      • Height adjustable back rest.

Despite the name, there is nothing ‘basic’ about this chair.  It comes with all of the chair adjustments its’ big brother Xenium DuoBack® has to offer.

The basic element is in the fabric finish. There are no mesh panels on the Xenium Basic chairs, a design feature which is heavily present throughout the full Xenium chair range.
