@asawilliams – I also recommend the Herman Miller Aeron. I’m sitting in one now in the home office and have had one at work going on 16 years now. Glorious. Can’t say enough. Beyond classic.
1.) Be sure to get the right size! Up under the back lip there are little brail dots:
– 1 dot = size A
– 2 dots = size B
– 3 dots (in a triangle) = size C

There are some HUGE custom jobbers too. There are also quite a few different arm configurations – maybe ~20. There is also a lumbar support pillow option. So if comparing prices online, you may be comparing apples to, well… sliced apples.
2.) Check out the Herman Miller Mirra too. They are a bit cheaper, crazy colors, and they have some diddly-do about “90%” recycled (if that tickles your fancy.) I have never sat in one, mind you, but they look similar. I was stunned recently by their marvelously not-black colors.
Otherwise the Aeron is a guaranteed slam-dunk.
Good luck!
