best writing chair

[sukha]

I'm on research leave with a ridiculous amount of writing to do. I need a new desk chair and would like to know the best desk/writing chair you've every had.

I'm vacillating between an eiffel armchair dwell.co.uk/138804
or (more sensibly probably) a desk chair a la www.staples.co.uk/rebel-operator-chair/cbs/404808.html?promoCode=300300666&Effort_Code=WW&Find_Number=404808

Obviously I'm procrastinating ... but any help would be appreciated.

I use a gym ball... Not too expensive as a starting point?

Gym balls are not advised any more if you have back issues. I have a herman Miller. Totally worth the money!

To me it doesn't matter on what I sit while I'm writing. I've been working as an online essay editor for quite some time and never I've thought about such things as writing desk and chair. Well, after reading your post I started thinking about what kind of chair would suit me and I guess I'd go with something like this. Not sure how comfortable it is but it does look awesome.
