Jewellers are horrified at my chair. It is a very old office chair.
Adjustable height but very low and on casters.
It is very hard with no real padding.
I sit on my buttocks with my thighs straight and my feet on the
floor, my back upright and have done so for 40 years.
My bench pin is at about nose height. My saw V is lower and to the
left and my soldering area at a different height to the right.
Also my polishing motor at another height. All carefully chosen.
I have never had back problems caused by my jewellery work.
I am 71, I am thin and stand straight.
Planning heights and sequences of work and positions in the workshop
is vital, as some of my younger plump hunchback jeweller friends are
finding as they visit various back quacks.
