Whiplash NeckrestNeck support is high priority for somone with whiplash.

Whiplash neck rest on the orthopaedic office chair allows resting of the neck muscles and helps ease backache and shoulder pain

For treatment to work it is very important to prevent further strain to the neck.

Whiplash sufferers often need to rest their neck more often.

Balans Correct PostureThe neckrest on the Orthopaedic Office Chair HNW3 extends out an extra 40mm and has a extra curve, so that it can be easily used by the user intermittently as they work.

This is the perfect office chair to relieve neck pain after a car accident.  The HMW3 office chair will help you sit comfortably throughout the day.

Along with extra neck support the HMW3 chair provides dynamic seating with constant back support.  You decide how you sit and this office chair will continue to support your body in all positions.


HM Back Chairs full support in every sitting positionHM chairs offer unrestricted movement when sitting, which means the user can sit upright, stretched out, poised or reclining without touching a single lever.

This makes them ideal for people who split their time between the computer, desk and telephone.

This is made possible by the HM Mechanism which uses three independently moving pivot axles—the seat pan, the rocker action and the back rest.

Back Chairs HM chairs complete back support from KOSThe whiplash neckrest ensures the neck support is within easy assess to the user no matter which seating position they choose

HMW3 chairs adapt to suit the user.

The height and depth of the seat pan and the armrests are all adjustable, giving the user comfort and good support while working.
The rocker mechanism is also adjustable so the backrest gives support without feeling like the chair is rocking backwards or stiff.

Upright posture with full support HM Back Chairs
The height of the seat pan can be raised to a level where you can comfortably sit with a straight back.

HMW3 chairs improve breathing and blood circulation

The HMW3 line allows you to sit stretched out while reclining, with full support for your spine and without your feet being lifted off the ground.

This way you open your body and facilitate breathing and blood circulation.

HMW3 chairs give freedom of movement

HMW3 chairs allow the user to stretch out their body while sitting. The pivot axles tilt the seat pan forward at the same time as the backrest tilts backward.

This gives the user a comfortable position that gives your spine the full support it needs.

When you sit in this orthopaedic office chair you will feel the difference, not only will your feel the constant back support but you will also appreciate the complete neck support.

It will be easier to rest your neck when needed, thus relieving neck strain and avoiding neck pain.  An important part of whiplash treatment is avoiding extra neck strain and damage and that is why the HMW3 office chair is the best chair on the market for those suffering from whiplash.
