I bought a floor sample model with a full warranty here: www.ultimatebackstore.com/html/aeron/aeronhafloor.htm It was in new condition when it arrived. The person I spoke with was very helpful and friendly.
I have a really bad back. I sit in a recliner with a laptop and a table next to me with another flat screen monitor on it. This set up works best for me. A friend of mine stands when he trades. He finds that the most comfy for his bad back. Hope these tips help.
Another vote for the Aeron chair. Coach makes one in leather for those of you who are extravagant. I also use a hang ups inversion table to stretch out the spine. When my back hurts I use the table and I usually hear a pop in my back, probably freeing up a pinched vertebrae. www.inversiontables.com/inversiontables/hu-inversion.htm
I saw a commercial on TV some weeks ago for an expensive chi trainer machine. Someway I found it too overpraised to be true. Your post causes me to ponder again. Thanks!
I am 6'6" and got the C, it is fine for me. The other thing to do is raise your LCD/monitor with some phone books. I will get the ergotron lcd display stand and vesa lcd monitors next as 8 phone books for my two monitors does not look too pretty in the living room!
I had one of these. Was happy for some weeks with it until one day something happened to my hips while using it. Couldn't walk normal for a week after this. Also my knees felt odd after using it. I think the position is just too abnormal for a human body.
Just got my size "C" Aeron delivered yesterday. Bought it on Ebay for $590. Dang near brand new. I used a knee chair a few years back, and I felt it helped me sit all day doing CAD work. I also have an Inversion Table. It helped with my bad back until I carried a bunch of big monitors up and down my office stairs. I will use it again after I completely recover from my back surgery - undertaken to fix a herniated disc - probably caused by the aforementioned monitors. The Aeron chair seem very comfortable so far. I think it take a few days to get completely used to it.
