DuoBack® Dynamic Movement
 

The perfect backrest has to fulfil two apparently contradictory criteria; It should not only support the upper body and take over the function 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 'DuoBack' 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.

Height adjustable, the backrests correctly support the back of any person.  The space between the pads allows the spine to move freely.  Instead of putting pressure on the spine, support is evenly distributed throughout the back muscles.

 

The backrest are pivotally mounted enabling them to move in all three axes - forwards and backwards; up and down and left to right.  It means that the back is fully supported in all positions.  Uniquely, the mountings provide the back with 'active support'.  The shape and mobility of the backrest ensure that they follow the contours of the back as it moves, varying the support needed and stimulating muscle tone and blood circulation.

DuoBack® is office ergonomics perfectly applied.

Each DuoBack® pad is independently mounted on a firm yet flexible bracket.

They are designed to flex and move as you do, continually adjusting to changes in your posture.  They will 'hug' your back when you are seated and each pad will adjust itself to the unique shape of your back...

... The vertical gap between the DuoBack® pads reduces direct pressure on the spine by up to 50%.  Recommended worldwide by physiotherapists, medical professionals and work place assessors for the support and ergonomic excellence DuoBack® provides.

The DuoBack 11 chair has lateral adjustment of the back rest pads.  The further apart the pads are set, the greater the flexibility.  The DuoBack has earned the nickname 'Hugger' because it does just that.  The further apart the pads are adjusted, the more they will 'Hug' your back.

If you do not wish to have such flexibility in the back rest movement then closing the gap creates a firmer back support.  However, there is still some movement as this is what the DuoBack is designed to do! 

The independently mounted DuoBack back rest pads flex and move with your movements.  This flexibility ensures that when you place pressure on the top of the back rest, however slight, greater lumbar support is achieved as the lower section of the backrest pads push forwards into the lumbar region.

'3D' Armrests adjust in width underneath the seat and also by rotating the offset PU top pads by 180° to bring them closer together.  This combined adjustability means that the armrests will accommodate an elbow to elbow width measurement of between 360mm and 620mm.

Further width adjustment and fine tuning the support for your arms is achieved by rotating the arm top pads to the desired position.  This adjustment ensures that your arms are supported in a natural position, allowing your upper arms to be positioned at the sides of your upper body.
