The dual backrests that make the Duo-Back so unique, conform optimally to the shape of thorax. The dual backrests not only support in the forward and backward motion but also in the side-to-side movement. The padded elbow rests, are so cleverly designed that they can be adjusted to fit any body size. The padded support area makes it possible to sit on this chair and work without putting pressure on the elbows.

Through the combination of the permanent, forward and backward leaning movement, and the new mobile individual backrests, it is possible to work with the back supported in almost any position. Because the backrest hugs the waist, the thorax is lifted. This can lessen the weight on the lumbar vertebra by up to 20 Kg.

The parameters of the Grahl Duo-Back are so variable that it can be adjusted to fit all body shapes and sizes, and the individual needs of the user through the adjustments of seat height, distance between the dual backrests, backrest height, seat angle, height of the arm rests, adjustable elbow supports.
