Xilium Mesh Back

Just when we thought it couldn't get any better, Michael Ballendat, the designer of our Xenium seating range, has come up with another stunning design and range of chairs for our ever growing collection.

There are some truly unique features in the Xilium collection, such as X-Move, a flowing lateral movement of the backrest.

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.

Finished in black or white with black tops.

Do You Need A Forward Tilt?

The following available upgrades are:

You can add a forward tilt to the seat.  It is independent of the rest of the chair and raises the rear of the seat up by +4°

A seat tilt rotates the pelvis forwards, in doing so it creates a natural, healthy 'S' posture to the spine and encourages you to sit upright.

TY47: Basic Tilt

Activated by shifting your body weight forwards and positioning your legs slightly back.  This is a tilt action that adjusts with your posture, unlike a fixed forward tilt which is either on or off..

Available with manual or auto-adjusting weight tension.

SIN-ST: Advanced Knee Tilt 


Our latest, dynamic back rest

adjustment, X-Move, a unique and supportive back rest feature only available on our Xilium operator chairs.

X-Move has no levers or fiddly knobs.

Simply lean to your left or to your right and feel the benefit of the greater level of support to your back.

Head Rest:

Xilium's head rest has plenty of adjustment and support, it can be adjusted in height, depth and angled.

Upholstered to match your choice of fabric or leather.

If you really want to get creative, select one finish for the cushion and another for the edge runner!

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.

Design Features: Make It Yours

Frame Finish:

Xilium's default colour finish for the frame is black.  However, there is a popular and 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.



  • Back rest outer shell

  • Arm rest frames

  • Back rest upper frame

  • Back rest lower frame.

  • 5 star base



  • Back rest outer shell

  • Arm rest frames

  • Back rest upper frame

  • Back rest lower frame.

  • 5 star base


A timeless, classy, classic finish.  You can have both the black frame finish with polished aluminium and the white frame with polished aluminium.

Three key components are available in a polished aluminium finish.

  • 5 star base

  • Back rest lower frame

  • Arm rest frames

Black (Standard)



Mesh Backrest Design:

Choose a mesh finish for your back rest.  The standard mesh finish for Xilium is AX, or you may prefer WX, the alternative.


Both finishes have a colour choice or grey, or black. 

AX - Standard Mesh





WX - Alternative Mesh





Fabrics, Vinyls & Leathers:

Your chair will be upholstered throughout in the fabric, vinyl or leather of your choice.  This means the seat, and where applicable, neck rest, will be finished in your colour throughout.  The seat and neck rest have edge upholstery, or 'Runners' as we call them.  As standard these too are finished in the fabric, vinyl or leather of your choice to match the rest of the upholstery work.

Xilium chairs offer flexibility in the runner finishes.  If you choose Radio or Step as your fabric finish, you may also choose a complimentary or contrasting colour from within the same range for the runners.  Or you can also choose any colour from our Runner 3D fabric range.

For example, this Xilium Mesh chair seat and neck rest is finished in Xtreme fabric XR009 and the seat and neck rest runners are finished to match.  This is the standard finish design.

Whereas here, the client chose Radio fabric RDF8033 for the main colour of the chair but opted for a complementary fabric for the runner edges.  In this case, Radio RDF3094. 

Main: Xtreme fabric XR009

Main: Radio fabric RDF8033.


Xtreme fabric XR009

Runners: Radio fabric RDF3094.

Xtreme: XR009

Radio: RF8033

Radio: RDF3094
