Thoughts on these types of chairs?
I have a job where I sit at a desk most of the time. The chairs are pretty standard rolly chairs which is fine for like an hour or two, but throughout the day it starts to hurt my back and puts a lot of pressure on my hips. I'm considering something like this maybe but I need in addition still the ability to lean back like a normal chair for some back support on ocassion and if it's possible a way to lean on my sides. I just started searching so I haven't gotten far enough to compare, is this generally the standard or is there something that would fit my needs better? What's been the overall experience with these? Are they really worth it?
Important note: I have arthritis in my knee so I cannot bend into a full crisscross applesauce. I can bend inward about 80% normally but only about 60-70% during a flareup.
