For ARCHITECTS. ‘Coolness’ is the word.

 Architects & office chairs.   For New offices ‘Coolness’ is the word to  excite media interest for both the company and for  Architects or Designers.   Most firms aspire to project this cutting edge image.    A 2T chair answers this exactly and in addition reduces LBP and increased productivity by lessening stress and morbidity.

Many distinguished architects have tried their hand at chair design.

A few examples are shown.

Screen Shot 2018-12-13 at 16.04.05Great architects, as can be seen from their efforts, have been sorely lacking in knowledge of ergonomics  when it is only ergonomics that determines comfort and avoids harm to the spine.   

See also how they have muddled the ergonomic advantages of the Roorkee chair.   However, bright young  architects already see the point.   This early example by Aaron Chetwynd was much admired.   Deliberately looks traditional so as not to excite Familiarity Bias, and frighten the horses.  With only a few minor design alterations it is ready & suitable for a 3 or 4M model.

Architects play an important part in development.

They are able to dictate requirements for projects.   Ergonomic knowledge  becomes vital to avoid stipulating work chairs with potentially harmful outcomes.

THE RELEVANCE OF THE 2t  (3M, 4M) concept

All the relevant factors are ticked :-

Office ergonomics

Poor seating is a major stressor resulting in reduced performance and absenteeism. (☛OFFICE HEALTH, Stress & Ergonomics ) and is of importance for Architects.   At present I know of no chair in the market that fully remediates this.     New seating concepts are coming forward which will not only revolutionise seating but also impact on office design. In a few decades a chair set before a desk, and arranged in straight lines will be perceived as not only dated but hopelessly inefficient. There is an increasing interest in this direction (☛WORK-CHAIRS, a new breed with a reclined mode. )     Also see Mindjet which with much hype describes GlaxoSmithKline’s purposed “deskless office” below.   ‘Great it ain’t’ but shows the way things are going.Screen Shot 2016-01-15 at 20.22.14

The designers of this layout obviously did not have the benefit of having seen the work of John Jukes described in  ☛OFFICE HEALTH, Stress & Ergonomics⇒ which were tested in the field but has not been universally adopted.  His recommendations for Office Environment Optimisation  achieve lower staff stress levels and higher productivity.    For a discursive account See Office environment stressors→

 Peter Bessey wrote to me  “Desks are rather a thing of the past – Dickensian even. They evolved as tables with storage developed, alongside chairs. The whole combination seems a way of reducing/avoiding the need for floor sitting or squatting and a means to provide a convenient standing/sitting presentation of objects for working with at an ergonomically higher level.  They were there to support and present paper documents and the like. Hardware, since then, was largely developed to be used with/on them and has evolved through typewriters and similar devices to today’s electronics. Once that demand for physical documents has been reduced and even eliminated by ‘paperless’ office tech., then there is once more a blank page to draw on.”

In the home sitting is less prolonged and less stringent ergonomic requirements can be allowed. ☛  EASY CHAIRS  .  It is still advisable for ergonomic adverse chairs be avoided.

Dear Henry
Very good account.
Good environmental design for offices must include ergonomics of the workplace to lessen musculoskeletal problems which are common and cause a high degree of absenteeism as well as low productivity. Field trials have shown how a good chair perhaps costing more initially improves the health of the occupant, increases their productivity and decreases the risk of absenteeism.
