As long as I had a good hard chair pad so the casters won't catch in the carpet, it wasn't a problem for me to turn 60-ish degrees from facing my computer to facing my client. But with a cranky low back/hip, it might be more problematic. At very least you'd need to be conscientious about alternating which foot you use to push off. It is worth spending a bit of extra money just so you don't get a rickety one that you're constantly having to tighten the bolts, and it's been a while since I looked at them, so no idea what they might cost these days.
