- Office managers should consult this blog as a resource (→For OFFICE MANAGERS).

- A combination of the above.
- A full remediation can only be achieved in a relaxed, reclined position that avoids all the adverse effects of prolonged upright sitting. This conclusion became validated by independent work using pMRI scanning (Smith 2007). This confirmed the 2Tilt (3M) concept. (Reclined mode→).
In practice a reclined mode for prolonged work demands:-
- For prolonged work, a fully supportive reclined mode→
- An upright mode for certain short tasks.
- An easy transition mode, preferably unstable for additional health benefits. UPRIGHT MODE & TRANSITION →
This involves a number of requirements. To be effective these are detailed in the (→The 2 TILT CONCEPT.). Although originally considered outlandish, recently design is at last moving in this direction and the 2T concept will inevitably and logically move into the mainstream of chair design.

Some essential reading for designers of ergonomic chairs and retail office chairs if they wish to improve the ‘ergonomics’ of their models with overwhelming health selling points. Chair designers still lose out, often having familiarity bias in recognising the underlying bio-mechanical essentials for a chair that will supersede the existing ‘cool’ models. ☛ Chair DESIGNERS & Low Lumbar Backache→
For MANUFACTURERS of retail office chairs new ideas can create both threats and opportunities.
Manufacturers can be reassured that feasibility indicates that existing components can be used , avoiding the 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 →
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 answers this exactly and in addition reduces LBP and increases productivity by lessened morbidity and stress. Also see
