I occasionally have back problems. Sitting in my $129 generic office chair from Office Depot I couldn't sit for more than 10 minutes without having to get up (painfully), take a break and lie down. Go to work and sit in my $600 Aeron and I can go a full day (with intermittent walking breaks) without significant discomfort.
AERON ROCKS!
I had a kneeling chair when I was 18, it worked fine, never had any complaints.
