Investing in an ergonomic office chair can save your spine (and money) in the long run, even if you spend most of your time standing at your desk. We tested four, then had a chiropractor select the best. After several 'Men's Journal' staffers sat in each chair over a period of two weeks, we called in Dr. Leon Aibinder, a New York City chiropractor and ergonomics expert who focuses on sports-related injuries, so he could take a seat. He evaluated each chair based on overall support, comfort, and ease of use.
The ReGeneration was built with a minimalist's touch and is basically the skeletal structure of a chair. But it's built for a wide array of sitters, with a flexible open-backed plastic frame that cradles comfortably and a slightly padded seat that's supportive without being overstuffed.
Dr. Aibinder says: "This chair has a great controlled recline that keeps your core active. It's not as cradling as the Mirra 2, but it's close." [From $677; knoll.com]
