Xenium Basic

Despite the name, there is nothing 'basic' about this chair.  It comes with all of the chair adjustments its' big brother Xenium Classic has to offer.  It will comfortably accommodating users between 5'4 - 6'4".  Add a headrest and it will provide perfect support above 6'4" 

The basic element is in the fabric finish.  There are no mesh panels on the Xenium Basic chair, a design feature which is heavily present throughout the full Xenium chair range.

We now offer it in a white edition.  For other chairs in white, take a look at either Xenium or Xilium where white is also an optional finish.

At Home


Whilst it is true that all of our seating is primarily designed for use in a busy modern office, the current climate means many more of us are working from home.  To us, now has never been a better time to stress the importance of ergonomics, especially in the 'office at home'.  Many companies take workplace ergonomics very seriously as they look after their staffs' well being.  So the chances are you have a good quality office chair, at the office.

But what about at home?  We hope that you will consider how and what you sit on away from the office and that you don't just make do!

If you are looking to purchase a quality chair for home, look out for any of our fabric, vinyl or leather finishes marked with the following symbols...

These markings indicate that the finishes have been tested to meet European and British standards in regards to fire and flame resistance and we hope, offer extra peace of mind when used at home.

Xenium Basic Standard Adjustments:

Seat Height Adjustment


Seat Depth Adjustment


Independently Height

Adjustable Back Rest


Multi-Lock Synchronous Action With Weight Tension Adjustment

A clever design feature of all Xilium and Xenium operator chairs is that when the back rest is raised in height, it also travels backwards.  This means that if you are tall more of the seat is exposed for a longer upper leg.  Combined with the depth adjustment of the seat Xilium and Xenium chairs can easily and comfortably accommodate the taller user.  In contrast, by lowering the back rest and reducing the seat slide, it will also adjust to more petit individuals.  This is a perfect ergonomic workplace solution for multiple users of various sizes. 

Xenium Basic options:


A60: 2D Armrests

Height adjustable arm rests.  Slight rotation of the front of the arm.

Height, width and depth adjustable arm rests.

A64: 3D Armrests

Height, width and depth adjustable arm rests.

'3D' Armrests adjust in width

underneath the seat and also by rotating the offset PU top pads by 180° to bring them closer together.


Further width adjustment and fine tuning the support for your arms is achieved by rotating the arm top pads to the desired position. 

Neck Rest:

As an integral part of the aesthetic design of Xenium, the headrest is finished in grey mesh, or black with black edition.


However, if you would prefer the headrest to match the main colour of your chair, it is possible for us to upholster it in a matching colour.  A top tip to consider... is that light colour headrests do not fair well over time! 


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:

Xenium Basic has a contoured back rest cushion to provide lumbar support.  The depth of support can be increased by one of two options.


Finely detailed push button lumbar depth adjustment, integrated into the back upholstery. 


Hand pump pneumatically depth adjustable lumbar support.
