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 decent 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.

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. 

DuoBack®

Each DuoBack® pad is independently mounted on a firm yet flexible bracket.

They are designed to flex and move as you do, continually adjusting to changes in your posture...

... They will 'hug' your back when you are seated and 

each pad will adjust itself to the unique shape of

your back...

... The vertical gap between the DuoBack® pads reduces direct pressure on the spine by up to 50%.  Recommended worldwide by physiotherapists, medical professionals and work place assessors for the support and ergonomic excellence DuoBack® provides.

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 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.  

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.

Pressure relieving memory foam for the seat.

Often overlooked but actually very important!

Soft wheeled castors for hard surfaces such as wooden or

tiled floors.
