Designed to Fit Your Needs

Michael Ballendat, the designer of our successful Xenium seating range, has now designed Xilium.  A collection of three task chairs built around a combination of ergonomics and design.   Each chair is fully adjustable with further enhancements to choose from. The design creativity is in your hands, through the many available options, frame colours and beautiful upholstery finishes to play with.

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.

Xilium Classic 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.

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.

Seat 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.

Advanced Knee Tilt 


The human body moves on three planes – frontal, sagittal, and transverse. If a only a chair allowed this kind of movement, looking after the well-being of your spine and the musculoskeletal system whilst seated. Our solution is our patented X-MOVE mechanism.


X-MOVE allows dynamic movement on the frontal plane, or to the sides. In addition, it activates a tiny rotational movement in the lumbar area. A thing to remember is that healthy sitting is dynamic sitting.

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.

Soft Castors:

Often overlooked but actually very important!

Soft wheeled castors for hard surfaces such as wooden or

tiled floors.

Memory Foam:

The use of pneumatic visco-elastic foam in the seat ensures comfort and reduces pressure on the sciatic tumors. This material reacts to body heat increasing its flexibility (regardless of the ambient temperature).

Lumbar Support:

Xilium Classic comes with an integrated lumbar support in the backrest cushion.  For greater depth and firmer support, we recommend this, our depth adjustable lumbar support 

Frame Finish:

Xilium's standard colour finish for the frame is black.  However, there is a popular and growing demand for white and 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.


Fabrics & Finishes

Colours have a great power. They influence our mood,can positively stimulate and be the perfect background for effective work and communication. The finishes we offer have been selected according to the current trends because finishes are not only about colours but also texture, shape and tone which when combined together create a full emotional experience


The finishing touch is the upholstery and we use some of the best, accredited mills, including Camira, Kvadrat, Fidivi & Gabriel®

Colours Are Emotional

Your chair will be upholstered throughout in the fabric, vinyl or leather of your choice.  This means the seat, back and where applicable, neck rest, will be finished in your colour throughout.  The seat, back rest 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 range for the runners.  You can also choose any colour from our Runner 3D fabric range too.

For example, this Xilium DuoBack is finished in Erika fabric ERF6005 and the seat and back rest runners are finished to match.  This is the standard finish.

Whereas here, the client chose Radio fabric RDXF1510 for the main colour of the chair but opted for a complementary fabric for the runner edges.  In this case, Radio RDF1008. 

Erika: ERF6005


Main: Erika fabric ERF6005.

Runners: Erika fabric ERF6005.


Main: Radio fabric RDXF1510.


Runners: Radio fabric RDF1008.
