The whole hierarchy of office chairs has always baffled me. You have three general classifications of chairs (and they're usually labelled as such at the store): Executive, Manager, and Secretary. The Secretary chair always sucks. It's the cheapest model, doesn't usually have arms, has thin or no padding, and it's flimsy. The Manager chair is the most comfortable. It's ergonomic, has adjustable armrests, lumber support, etc. The Executive chair, which should be the most luxurious, is almost always the most uncomfortable but it's always covered in slippery leather. Other than that, it's straight-backed, never high enough for the desk, and heavy.
It makes no sense that the degree of comfortableness that you are allowed to have is actually a class system in a modern office. I get that a business owner wants to control costs and expensive chairs are expensive. But wouldn't you want your employees to be as comfortable and healthy as your budget will allow? Why is a secretary less deserving of arm rests or lumber support than a manager?
