New ideas can create both threats and opportunities , once both familiarity  and normalcy biases are overcome.  Creative disruption works.

to architects

For New offices ‘Coolness’ is the word to  excite media interest for both the company and the Architect/Designer.   Most firms aspire to project this cutting edge image.    A 2T chair, or the derived 4M workstation, answers this exactly and in addition reduces LBP and increases productivity by lessened morbidity and stress.  Also see  ☛  PRODUCTIVITY AND WORKPLACE STRESSORS→(Article published in EurOhs, European Occupational Health and Safety Journal, Dec 2002.by Dr HA Sanford)

To office managersAllows an alternative view to the usual hype, often laughably misguided, from manufacturers,

 

 

Spinal bio-mechanics dictates that prolonged sitting should be performed in a reclined position with frequent change of posture.  For a full remediation  a number of requirements are essential.   To be effective these are detailed in the 2T CONCEPT a full solution

This incorporates :-

  1. A reclined mode for prolonged work    ☛2T reclined mode→
  2. An upright mode required for certain short jobs.    ☛2T Upright mode→
  3. An unstable intermediate mode to enable a quick, easy transition between the 2T modes.    ☛2T transition mode→    ☛ dynamic seating→  With the recognition that the transition movement has physiological advantages, this has been upgraded to a ‘mode’.  The 2T now becomes a triple-mode (3M) concept.

‘Sitting disease’

Compared to people who sit the least, those who spend most time in a chair have a 112 % higher risk of developing diabetes, a 147% higher risk of suffering “cardiovascular events” such as strokes and a 49%t increased risk of death from any cause.  (http://www.telegraph.co.uk/wellbeing/fitness/sitting-disease-is-killing-us-and-exercise-doesnt-help/)   Alarming but not entirely an effect of the bio-mechanics and not examined here.  However some posts are relevant.
