Setu ChairYou spend enough time planted in your office chair that it's worth shelling out some petty cash for a good one. The Setu has a "kinematic" spine that flexes to accommodate your butt. There are no knobs or buttons to adjust. You just sit down and let the tuned elastomers do their flexible thing. Each chair will cost you $600, but that's a lot cheaper than a bunch of trips to the chiropractor. Plus, it's 93% recyclable which makes it as good for the environment as it is for your vertebrae.
