Sit in it and give it a shot. We did this a few jobs ago when we convinced management to buy good chairs for tech. We were surprised to find nobody in the office actually liked the Aerons. Personally, I found I wasn't a fan of the mesh back, but YMMV. We tried a few different chairs at the same shop and we all ended up almost simultaneously agreeing on preferring the HumanScale Freedom (http://humanscale.com/products/product_detail.cfm?group=FreedomTaskChairWithHeadrest http://humanscale.com/products/product_detail.cfm?group=Free...). I liked the chair so much I ended up negotiating to buy it from the company when I left (as they downsized all of tech into oblivion) and I still use it every day, ~3 years hence. The biggest lesson here isn't me saying "I prefer HumanScale" but that it is REALLY important to try chairs before you buy them. They're one of the most important tools for a developer, followed by not using a cheapo keyboard ;)
