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.

Soft Castors:

Often overlooked but actually very important!

Soft wheeled castors for hard surfaces such as wooden or tiled floors.

Memory Foam:

Pressure relieving memory foam for the seat.

Depth Adjustable Lumbar Supports:

Xenium Freework Classic comes with contoured cushioning in the back rest as standard.  However, for those that might want greater, adjustable support for the small of your back, there are three options available.
