For DESIGNERS, Architects & Office Managers


An account of the bio-mechanic (ergonomic) factors, associated with prolonged sitting,  accounting for mechanical spinal pathology (Backache, LBP, IVDisc pathology, CTD) and options for their remediation.

opportunities , once both familiarity  and normalcy biases are overcome.   Creative disruption works.
 A resource  if they wish to improve the ‘ergonomics’ of their models with overwhelming health selling points.      Manufacturers can be reassured that feasibility indicates that existing components can be used , avoiding Screen Shot 2018-06-03 at 14.10.04the expense of retooling, while preserving their brand image.
Prospective manufacturers can be helped to leap ahead of the field once their chair is shown to have optimised ergonomics.  ☛ Manufacturers  →

 

to architects ☛ For ARCHITECTS. ‘Coolness’ is the word to  excite media interest for both the company and the Architect/Designer.      It is very relevant to Interior designers and architects involved with office design.    Most firms aspire to project this cutting edge image.  A 2T chair answers this exactly and in addition reduces LBP and increases productivity by lessened morbidity and stress.(See below).

To office managersAllows an alternative view to the usual hype, often laughably misguided, from manufacturers,  Office managers should consult this blog as a resource (→For OFFICE MANAGERS).

 

To remediationThe scientific evidence identified adverse effects which occur with conventional prolonged mid-upright sitting that required remediation.

Backache & chairs.   A number of partial systems are described.

If configured correctly are of some help.  But these efforts to improve the ergonomics of upright chairs seems to have reached their limits without a great reduction in spinal disorders associated with prolonged sitting work.     Efforts have also been made to sidestep the problem :-

The time has come to move on. 

The reclined, relaxed position.

Screen Shot 2018-06-03 at 13.01.32Spinal bio-mechanics dictates that a full remediation for prolonged sitting that avoids all the adverse effects of prolonged upright sitting, can only be achieved in a  reclined  position .    This conclusion became validated  by independent work using pMRI scanning  (Positional MRI→) (Smith 2007).   ( also this confirmed the 2Tilt (3M) concept. (Reclined mode→).

This involves a number of requirements.   To be effective these are detailed in the 2T CONCEPT a full solution →.    Although originally considered outlandish, recently design is now moving in this direction.  WORK-CHAIRS, a new breed with a reclined mode.→

  • In practice a reclined mode for prolonged work demands:-
  • A fully supportive reclined mode, for prolonged work.
  • An upright mode for certain short tasks.
  • Screen Shot 2018-06-03 at 13.10.25An easy transition mode which is  preferably unstable for additional health benefits.
