DuoBack®

Granted, the name isn't so catchy but these two chairs have been with us for a long while now and DuoBack Type 11 and DuoBack Type 12 is what they are known as. 

They are the Original DuoBack 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.

Neck Rest:

Height and depth adjustable, the neck rest for the Type 11 & 12 DuoBack has a huge amount of adjustment.  It has a broad, plush yet supportive cushion.  It is designed to provide support at the nape of the neck, rather than the back of the head.

Additional Comfort:

Coccyx Relief Zone:

Hidden from view, our coccyx relief zone is a void at the rear of

the seat cushion which is designed to relieve pressure on the coccyx.

Memory Foam:

Pressure relieving memory foam for the seat.

Soft Castors:

Often overlooked but actually very important!

Soft wheeled castors for hard surfaces such as wooden or

tiled floors.

Forward Seat Tilt:

+4º of forward tilt to the seat.  Highly beneficial to maintaining a good posture

as it actively encourages a positive 'S' shape to the spine.

Base Options:

Black: Standard on both Type 11 & Type 12

DuoBack chairs.

Polished Aluminium: Optional on both Type 11 & Type 12 DuoBack chairs.  Looks very smart combined with A12 polished aluminium armrests!
