• Ergonomics 4 Work

    Over 90 % of jobs involve prolonged sitting and using a computer, and when an individual begins to experience discomfort then an assessment of their working station should be undertaken.

    These assessments are often referred to as Ergonomic or DSE Assessments (Display Screen Equipment) and can, in special cases, be referred to the Access to Work Government initiative for help with funding the correct equipment.

  • Research shows that 60% of adults could benefit from adjusting their work station equipment and invisible issues such as, tired eyes, back ache, headaches or RSI’s are very common.

    If left unresolved, these issues can have a huge impact on performance and morale, resulting in time off work and/or long term mobility issues.

    The key to healthy sitting is to maintain a natural “S” shaped spinal curve. This will minimise uneven compression of the spinal discs and muscular strain whilst improving respiration and circulation.

  • Height

    The height of the chair when sitting is the first priority and it is important to ensure a chair fits the users’ lower leg length in a number of sitting positions.

    Combine the chair with a footrest as well if the user is petite. Chairs come with various height gas lifts allowing for a different range of adjustment on each one. Feet must be firmly placed on the floor or footrest and an angle of just over 90 degrees at the knee is the angle to aim for. Keep adjusting the seat height until this is achieved.

  • Ensure the seat base can be adjusted backwards or forwards to maintain full support to the upper leg i.e between hip and knee joints.

    The aim is to allow for enough room for an unbroken blood supply to the lower limb and yet offer full support to the upper leg and thigh muscles to avoid tension and fatigue.

  • Back Support & Lumbar Control

    The lower back area should be entirely supported using both the back height adjustment to ensure the fixed curve of the chair sits in the small of the back and/or adjusting the lumber control to the correct pressure and curve.

    Taller chair backs should be considered for taller people or where additional shoulder and neck support are preferred, especially if a headrest is required.

  • To avoid repetitive strain injuries especially when using keyboards for extended periods of time, adjustable armrests should be fitted.

    These should be adjusted to ensure a 90 degree angle is created through the elbow but must also be fixed in conjunction with the height of the chair at the desk to ensure the user can get the chair close enough to the workstation to use the arm rests effectively. Wrists should sit level with the forearm and not angled to reach the keyboard, re-adjust the height of the armrest to attain this position.

  • Tilt Mechanism

    In order for a chair to offer support most of the time the user is sitting in it, ideally the chair should move with the user whilst adjusting position.

    Selecting a Synchronised tilting mechanism will allow the chair back and seat to adjust together to ensure the lumbar curve and upper limb support remains even whilst the user is shifting position.

    Being able to move whilst supported encourages blood circulation and therefore reduces fatigue and strains to both the mind and muscle.
