I've had few/any complaints since strapping one of these to my cheapo office chair (at the recommendation of a spine/back specialist):

The extra lumbar support is really comfortable, and it sort of subtly nudges you to stay in a healthy position. Even when I'm completely unmindful of my posture, it keeps a healthy arch in my back.

I also take a 20 - 30 minute walk at lunch several days a week.

I agree. Get a good chair.

Years ago, I had to sit in one of those leather OfficeMax chairs. I developed all sorts of back pain. I realized it was the chair when I changed jobs (and chairs) and the back pain went away.

People have a lot of opinions about chairs, but I really like the Aeron chair.

They're worth the price, even new. But if you poke around a little and don't mind being less able to customize than the Herman Miller site makes possible, you can probably find gently used castoffs for half retail price or less.
