I would much rather have a comfortable chair than free lunch everyday. Free lunch would save me some money but a good chair will save health problems down the road and make me feel better while working.

Why don't you trade the free lunch for better chairs?

I recently went ergonomic chair shopping and find it extremely hard to believe you can get a decent chair for $60-80. The price range was 10x that where I looked.

The chairs in this photo - http://dontrepreneur.files.wordpress.com/2009/12/office2.jpg - do not look anywhere near ergonomic. If it only goes up and down, it's not ergonomic.
