Grahl Type 11 Duo-back standard chair
Grahl Type 11 Duo-back standard 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.

The resultant 'dynamic sitting' stimulates the muscles, helping to prevent back strain or alleviate existing pain. Just as importantly, this stimulation retards the natural build-up of muscle tension, helping to lessen the effects of tiredness.

The unique split back pads of the 'Duo-Back®©' are positioned halfway between the top and bottom of the spine so that when reclined the lower sections of the pads move forward straightening the spine and pelvic girdle. This is a vital point often stressed by both back specialists and office ergonomists.
