I have the option to work form home the rest of the year.  My current chair isn't doing my back any favors.  I do have back problems from time to time (about 2 times a year I tweak it and I have a hard time walking normally for a few days).  So, investing in a good chair might be good.

I'm not opposed to buying one of those $1,600 chairs (aeron-chair/) if they really work, but I suppose I should just try a modestly priced one first.

Anyone have a chair they love?  Has anyone tried those Purple Cushions?  One for the back in particular: Purple Back Cushion 

Any other options that I should consider?

Thanks!
