I use a standard Office Depot leather desk chair. I think it cost around $180. It looks good, and more importantly it fits me like a glove. I actually went down to Office Depot and sat in all of their chairs that I thought looked nice, and then just picked the one that felt most comfortable to me.

I can sit in this chair 14 hours a day and never even notice it. I like that because I see my chair as being a productivity booster like using Zend Studio for php coding or Outlook for email. If I can sit comfortably all day (and all night, lol) I can really focus on what needs to be done.

If the Aeron Chair fits your body well go for it, but you can save a couple of bucks at a store like Office Max or Office Depot. They have the mesh chairs too, and you might find that one of these fits you much better than the Aeron.

Yes, I was thinking of doing the same thing this weekend– trying out all the chairs I can find, especially anything mesh. Thanks for reminding me! :)

I use a kneeling char (like Lisa Simpson has). It takes getting used to, but once your back, thighs, and stomach muscles have adjusted it feels really good.

How cool, I've never heard of those. Thanks for the idea, this might allow me to get closer to my desk, but it looks so strange!

Wooden "Captain's Chair" from an "antiques" place but really just junk from a bar. I sanded it to get rid of the nasty laquer and it looks decent now. Unfortunately it is absolutely uncomfortable and completely unsuitable for sitting here for any length of time. So, I am also looking for a new chair...I like the look of the Aeron's but would like to find a lower-priced alternative. Please tell us what you find!

I use the hag capisco. Works well for keeping my energy "upwards": strong firm seat that rotates the hip forwards. I find the aeron too saggy. You can get it with or without a backrest. I don't use a backrest cause that forces me not to slouch.

Cheap office chair from staples/office centre. Works fine, but I did rip off the arm rests so it can get closer to my work table.

Big leather sofa. Reclining. Plenty Cushions.

A Steelcase LEAPV2. Great chair.

A couch in my living room.

Global Airflow Leather Mesh-Back Chair (from Staples ~$200)

I have a standing-height desk and no chair.

Aeron at the office. My company is so 2000.

Bean bag on the floor.

Don't those get uncomfortable being in the same position after a while?
