Hi bcgirl. I tried one of the kneeling stools and although comfortable I could not spend long in that position and yes, getting in and out can be a bit tricky, especially if we are still.
At home at the computer, I have a therapy-ball chair with locking castor wheels. It helps maintain my core muscles and ensures better posture. I personally like it, but they too, take a bit of getting used to. It can tire you out to begin with, but after a while you don't even think about the fact that theres no backrest to lean against. (I notice now you can also get versions of them with backrests).
I also think it might depend on the fitness of your back and core muscles, if they are weak, maintaining the position could be difficult. I wonder if you could borrow one to "try before you buy" to see if its worthwhile.
Has anyone tried the ergonomic chairs where you sit "back-to-front" - you sit forward and instead of a backrest, there is a chestrest. Not sure if I could work like that, but I'd be interested to hear from anyone who's tried it.
All the best finding a comfortable chair. Let us know what you find works for you in the end. Cheers
