As an integral part of the aesthetic design of Xenium Freework Classic, the headrest is finished in grey mesh to compliment the mesh upholstery on the back rest and seat edges.


The standard colour for the mesh upholstery is grey.  However, you may choose a different colour from our 'Runner' fabric range.  If you would prefer the neck rest upholstery to be the same as the main colour of the chair, you can have this too.


Chairs finished in leather, have the option of a leather neck rest.  

The neck rest is height adjustable with some depth adjustment.  The mounting

​holder of the neck rest is flexible and moves back and forth when under weight.

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.

Lumbar Support:

Depth adjustable lumbar support.  Height adjustment is achieved in raising or lowering the back rest.  The lumbar

support gives you a firmer support to the small of the back.

Design & Finish Options:

Frame Finish:

All chairs in the Xenium range have the default colour of grey as the frame finish.  However, there is a black edition and a popular, growing demand for white, you can choose this too!  Certain components, such as arm rest tops will still remain black, so as to keep your chair looking clean and fresh.
